A Spitz naevus (or Spitz's nevus) is an uncommon type of mole ( melanocytic naevus). A Spitz naevus is a benign skin tumour. However, it may resemble a melanoma clinically and microscopically, so Spitz naevi are often excised as a precaution. Spitz naevi. Classic Spitz naevus Een Spitz naevus is een goedaardige, moedervlek met typische kenmerken zowel qua klinisch beeld als qua microscopisch beeld. Het is van belang om een Spitz naevus te herkennen omdat deze soms sterk kan lijken op een melanoom (= pigmentcelkanker). Om deze reden wordt deze moedervlek soms (onterecht) het benigne juveniel melanoom genoemd A Spitz nevus usually appears pink and is shaped like a dome. Sometimes, the mole contains other colors, such as: red; black; blue; tan; brown; These lesions are often found on the face, neck, or. multipele Spitz naevi - geagmineerde Spitz naevi - Spitz naevus - benigne juveniel melanoom - epitheloïd en spoelcelnaevus Summary We present two cases of young patients who were diagnosed with agminated Spitz nevi (ASN), a rare diagnosis. The etiology of ASN is largely unknown and diagnosis requires clinicopathological correlation Agminated Spitz naevi or metastatic spitzoid melanoma? Australas J Dermatol. 2018;59(3):e234-e235. 5.

.A type of melanocytic nevus, it affects the epidermis and dermis.. It is also known as an epithelioid and spindle-cell nevus, and misleadingly as a benign juvenile melanoma,: 691 and Spitz's juvenile melanoma).The name juvenile melanoma is generally no longer used as it is neither a melanoma, nor does it occur only in children Spitz nevi are acquired melanocytic lesions with a wide histomorphological spectrum; reliable distinction from spitzoid melanoma is often difficult. Misdiagnoses of benign spitzoid tumors as spitzoid melanomas and vice versa are attributable to a frequently disturbing morphology and inconsistent or Spitz nevi are uncommon melanocytic neoplasms found in children. Historically, the diagnosis and management of these tumors has lacked consensus among oncologists, pathologists, plastic surgeons, and dermatologists. Once interpreted and treated as a juvenile melanoma, many have argued for the benignancy of such tumors in certain patient age groups, encouraging a conservative approach Spitz naevi en melanomen kunnen voor elkaar worden aangezien. Daarom worden Spitz naevi soms als voorzorgsmaatregel agressiever behandeld. Foto's van Spitz naevus en melanoom Incidentie. Spitz naevi zijn niet erg gebruikelijk. Sommige schattingen suggereren dat ze ongeveer 7 op de 100.000 mensen treffen Een spitz naevus is een goedaardige moedervlek. Meestal ontstaat een spitz naevus voor de leeftijd van 2 jaar, maar ze komen ook bij volwassenen voor. Het ziet eruit als een rozerood tot bruinrood bol of ovaal gezwelletje, ongeveer 3-5 mm of groter. De diagnose wordt gesteld op 'het blote oog' en bevestigd door weefselonderzoek
Spitz/Reed nevi can be classified according six different dermoscopic appearances, namely, vascular (pink homogenous), globular, starburst, reticular, atypical and homogenous pattern. In their growing phases, Spitz nevi evolve from globular pattern to a starburst pattern with regular streaks at the periphery (finger like or globule like) Spitz nevus growths, or Spitz nevi, were once considered a type of skin cancer.They have since been shown to be benign, or non-cancerous, and relatively harmless Nevus spilus is a melanocytic neoplasm characterized by a tan macular background punctuated by multiple hyperpigmented macules or papules that represent various types of nevi. These include junctional and compound nevi, Spitz nevi, and rarely blue nevi..
Spitz nevi (message) Spitz nevi - participate! Below are dermoscopic features commonly associated with the diagnosis Spitz nevi . The example images have been approved by a panel of experts as representative of each given feature. For a more in-depth discussion of associated features, please see the Dermoscopedia page for Spitz. Spitz nevus are non-cancerous skin lesions that tend to be dome-shaped, red, reddish-brown or dark colored. They usually develop on the face or limbs of young children. They tend to grow quickly initially, but then stabilize or even disappear after a period of time. Spitz nevi can be very difficult to distinguish from melanoma, as a result treatment tends to involve excision of the nevi Spitz nevi were first described in 1948. 1 Spitz 1 originally called these lesions benign juvenile melanoma. She was able to identify and describe a separate class of benign melanocytic neoplasms in children that were previously diagnosed and treated as melanoma. 2 Prior to this discovery, the standard of care was to remove all suspicious pigmented lesions in children prior to adulthood to. Spitz nevus (Epithelioid and Spindle-Cell Nevus) is an uncommon, benign, melanocytic nevus that is usually acquired and has histologic features that overlap with those of melanoma.Spitz nevi were previously diagnosed as melanomas due to their similar appearance under a microscope, until it was found that they did not show malignant behavior
Spitz nevi were most commonly mistaken clinically for common melanocytic nevus, hemangioma, verruca, fibrous histiocytoma, molluscum contagiosum, granuloma pyogenicum, keloid, and melanoma. Histologically, there are various expressions of Spitz nevi, but they are usually compound melanocytic nevi with little pigmentation and typically large spindle- and/or epithelioid melanocytes Spitz nevi are benign melanocytic proliferations and, as such, have no invasive or metastatic potential. If histopathologic confirmation of a benign Spitz nevus has been confirmed, no further evaluation is required. The biological behaviour of atypical Spitzoid tumors is unpredictable, although the majority likely represent benign tumors
Importance Spitz nevi are benign melanocytic neoplasms that classically present in childhood. Isolated Spitz nevi have been associated with oncogenic gene fusions in approximately 50% of cases. The rare agminated variant of Spitz nevi, thought to arise from cutaneous genetic mosaicism, is characterized by development of clusters of multiple lesions in a segmental distribution, which can. Spitz nevus. A Spitz nevus is a type of mole. It also may be called a nevus, Spitz lesion, juvenile melanoma, benign juvenile melanoma, or spindle and epithelioid cell nevus of Reed. It is a group of nevus cells in the layers of the skin. Most people get moles during their life Spitz nevi occur predominantly in children, adolescents, and young adults, accounting for the unfortunate and now obsolete synonym of juvenile melanoma that was applied in the seminal works on these tumors. 570-572 Clinically, Spitz nevi are papulonodular, well-circumscribed lesions that often have a pink-red appearance rather than a pigmented one Melanocytic nevi with features of Spitz nevi and Clark's/dysplastic nevi (Spark's nevi).

Pseudogranulomatous Spitz nevus: a variant of Spitz nevus with heavy inflammatory infiltrate mimicking a granulomatous dermatitis
Spitz (spindle and/or epithelioid cell) tumors/nevi were first described in 1948 by Sophie Spitz as juvenile melanomas. 1,2 The incidence of Spitz tumor is estimated to range from 1.4 to 1.66 per 100 000, affecting all age groups but uncommon beyond the 4th and 5th decades of life. 3,4 Clinically, these lesions appear as well-circumscribed pink, tan, or brown papules or nodules with an. Spitz nevi are typically solitary, but multiple lesions, or even agminated lesions, may occur. • Spitz nevi present as a papule or nodule that may be dome shaped or even pedunculated. • Most Spitz nevi are skin-colored, pink, or red, perhaps with telangiectasia (Figs. 30.5 and 30.6) Spitz nevus is part of a group of skin tumours that are commonly called moles. The tumour is named after Dr. Sophie Spitz, a pathologist who first described Spitz nevi. Spitz nevi tend to grow quickly at first, forming pink or brown coloured bumps on the surface of the skin Spitzoid melanocytic lesions may be broadly categorized into Spitz nevi, ASTs, and spitzoid melanomas. 2-4 Classically, the Spitz nevus presents as a dome-shaped, pink to reddish-brown papule or nodule, usually less than 6 mm in diameter. 4 Spitz nevi commonly arise in childhood but may occur at any age. Lott et al 3 recently studied the clinical features of 484 Spitz nevi in comparison with. The Spitz nevus is a benign melanocytic neoplasm with two peculiar cytological characteristics: its cells are large and they are oval (epithelioid) or spindled in shape. It was initially described as melanoma of childhood, and later as juvenile melanoma and as spindle and epithelioid cell nevus
Spitz nevi are benign, acquired, melanocytic proliferations, which generally develop in children and adolescents, although it also occurs in adults. Spitz nevus was first described by Sophie Spitz in.. Spitz nevi often display at least 1 of the dermoscopic melanoma-specific structures. • The most common melanoma-specific structures seen in Spitz nevi are atypical network, negative network, crystalline structures, atypical dots and globules, streaks, blue-white veil overlying a palpable portion of the lesion, atypical blotch, and atypical vascular structures Kamino Body in Spitz Nevus High-power examination of this case shows a small, densely eosinophilic-staining Kamino body , which is an eosinophilic globule found at the dermal-epidermal junction.These are typical of Spitz nevi but are not seen in most cases
A subset of Spitz nevi poses substantial diagnostic difficulty, even among experts, due to its resemblance to malignant melanoma. These lesions are termed atypical Spitz nevi/tumors and there is. Spitz nevus Een Spitz nevus is een halfbolrond tumortje (roze, rood, bruin) dat ontstaat in weken tot maanden bij kinderen of jonge volwassenenen, 3-5 mm of groter, kan histologisch op een melanoom lijken, klinisch goedaardig (zie onder Spitz naevus) Spitz nevus is an acquired melanocytic lesion, which generally develops in children and adolescents, although it is not rare in adults. It is classically believed to be benign, and conservatively. Intradermal Spitz nevus is a distinctive type of Spitz nevus that sometimes can be difficult to define given the unusual features that these lesions can show; thus, strict application of well-defined histological criteria and awareness of their morphological spectrum will facilitate definitive diagnosis Atypical Spitz nevus. Spitzoid melanoma: asymmetric, irregular lateral borders, uneven base, pagetoid scatter of melanocytes, uneven nests of melanocytes, lack of maturation, spindle cells not perpendicular to surface, epidermal spread, ulcerated surface, most cells appear malignant ( Clin Dermatol 2009;27:545 ) Back to top
The Spitz nevus has long been defined as a benign melanocytic lesion that shares many histologic features with malignant melanoma. Despite the diagnostic criteria established for these two entities, their histologic similarities continue to make their distinction somewhat difficult. Uncertainties also exist with regard to the natural history of. Fig 1. Clinical photographs of Spitz nevi. A, Classical Spitz nevi most frequently occur on the face. B-D, They appear as pink to red, well demarcated, dome-shaped papules that can be ulcerated. E, A minority of Spitz nevi are pigmented. F andG, Dense blue-black pigmentation is characteristic of the pigmented spindle cell nevus of Reed, which some consider a variant of Spitz A conjunctival Spitz nevus is a very rare, benign me-lanocytic lesion, which can be mistaken for a malig-nant melanoma. We present a case of a 28-year old man, who suffered from a rapidly growing, non-pig-mented mass in the left caruncular area, extending to the nasal conjunctiva INTRODUCTION. Spitz nevus (or Spitz tumor) is an uncommon melanocytic lesion composed of large epithelioid and/or spindled cells. It typically presents in childhood or adolescence as a sharply circumscribed, dome-shaped, pink-red papule or plaque most commonly located on the face or lower extremities ().The clinical relevance of Spitz tumor lies in its close histologic resemblance to melanoma
Two nevi, one on the right ear and the other on the right knee, were biopsied and diagnosed as desmoplastic Spitz nevi. Upon targeted next‐generation DNA sequencing, both harbored BRAF fusions. Copy number alterations and fluorescence in situ hybridization (FISH) for BRAF suggested that the fusions arose on the ring chromosome 7 Spitz nevus are rare, benign moles that closely resemble melanoma. They usually appear before the age of 20, however, they can appear on adults as well. Because their appearance closely resembles.
A Spitz Nevus can range from a few millimetres to 1-2 centimetres in diameter. They generally appear on the face or limbs. The growth is usually solitary; however, it is possible to have multiple lesions. They tend to grow quite rapidly and can disappear spontaneously after some time.

Spitz nevus is a benign melanocytic nevus with a characteristic histological appearance. It is otherwise known as benign juvenile melanoma or nevus of spindle/epitheliod cell type. Most lesions are under 1 cm in diameter and the majority are pink to red in colour and may be mistaken for a pyogenic granuloma. Histological examination shows an intense melanocytic activity around the dermo. Plexiform Spitz nevus: Plexiform arrangement of predominantly spindle and epithelioid melanocytes. Desmoplastic Spitz nevus: Variant of a dermal Spitz nevus in which usually a few epithelioid melanocyte nests are located in a fibrosed dermis with broad, tangled collagenous fibre strands. Differential diagnosis Spitz nevi usually involve both the epidermis and dermis (i.e. compound Spitz nevi), although occasionally they may be located entirely at the epidermal-dermal junction (junctional Spitz nevi) or within the dermis (intradermal). They are symmetrical, well-circumscribed and wedge-shaped,. . Spitz nevus and melanoma share these large spindle and epithelioid cells, but the following list shows the particular features that drives the diagnosis towards Spitz nevus instead of melanoma: . Sharp lateral circumscription; Maturation from the top to the bottom; Absence of deep mitotic figures; Reed nevus (or pigmented spindle cell nevus of Reed
. They usually develop on the face or limbs of young children. They tend to grow quickly initially, but then stabilize or even disappear after a period of time. Spitz nevi can be very difficult to distinguish from melanoma, as a result treatment tends to involve excision of the nevi Spitz nevi have been found to be associated with a low percentage of mutations in the H-RAS gene; however, the mutational profile of H-RAS in Spitzoid melanoma is unknown. METHODS. The authors evaluated a unique series of melanomas occurring in prepubescent children that showed Spitz nevus-like histopathology (Spitzoid melanoma) Spitz Nevus. Photos - click on tab labeled Spitz nevus. Children and occasionally adults can develop a melanotic neoplasm called a Spitz nevus, named for Sophie Spitz, a pathologist. This lesion is typically a rapidly growing pink nodule, but the lesion can sometimes be pigmented. Histologically this benign lesion can be easily confused with.

Reed nevus is characterized by a dark brown or black papule or plaque, often affecting the lower limbs of young women around the third decade of life; however, it can occur in children and young adults of both sexes (Figure 2).11,14,16,21 It is usually smaller than Spitz nevus. 16 It can grow fast. Less frequently, it may present as hypo-or amelanotic. 13.21 Pathologists occasionally find. Other Tests. Histopathologic evaluation of a suspected Spitz nevus is indicated. The value of including individual proliferation index and histopathological parameters (eg, Ki-67, Pi-21, fatty acid synthetase) into models of predictive probabilities is uncertain, but a panel of markers including Ki-67, HMB-45, and S100A6 can be helpful in establishing a histologic diagnosis A nevus (plural nevi) is a mole on the skin that can occur on any part of the body. A Spitz Nevus is an uncommon, benign condition that occurs as a pigmented skin lesion. The lesion is usually a well-defined nodule, less than 1 cm in size. It can be present anywhere in the body, though often they are seen in the head and neck region
Wat Is Spitz Nevus? Een Spitz naevus is een goedaardige groei huid die meestal wordt gezien bij mensen die minder dan 20 jaar oud. Het is ook bekend onder de termen goedaardige juveniel melanoom of epithelioid en spindel-cel nevus. Deze laesies verschijnen als pijnloos The Spitz nevus, also known as benign juvenile melanoma or a nevus of epitheloid and spindle cells 2, was first described by Sophie Spitz in 1948 1 and is most common in children and adolescents. 3 They can present in three different ways: solitary nodular, multiple grouped, and multiple disseminated. 3 The great majority of lesions are solitary, nodular, and are present in children and. Nevus Spitz is a benign melanocytic proliferation, first described in 1948 by Sophie Spitz as a childhood melanoma. Initially, it was described as an erythematous papule or node, but further studies of the Spitz nevus proved that in 71-92% cases i Spitz Nevus in a Hispanic Population: A Clinicopathological Study of 130 Cases.

Spitz nevi are benign moles. WHAT DOES A SPITZ NEVUS LOOK LIKE? A Spitz nevus often looks like a pink, raised bump. It can also be a blue, brown, or black flat mark or raised bump. When a Spitz nevus first appears, it will typically grow for a few months. After that time, the Spitz nevus should stop growing and stay the same size, shape, and color Histopathologic evaluation of a suspected Spitz nevus is indicated. The value of including individual proliferation index and histopathological parameters (eg, Ki-67, Pi-21, fatty acid synthetase) into models of predictive probabilities is uncertain, but a panel of markers including Ki-67, HMB-45, and S100A6 can be helpful in establishing a histologic diagnosis Junctional, compound or dermal nevus, composed of epithelioid melanocytes (large, with broad, pink cytoplasm, sometimes multinuclear). Compound Spitz nevi show often mitotic activity. Intraepidermal melanocytes are organized in nests and in single units and often epidermal scatter is present. Melanocytes are (at least focally) spindle-shaped. Spitz Nevus return to: Melanoma (Evaluation and Management) see also: Case Example Atypical Spitz Nevus Affirmed at Melanoma Tumor Board on 1-24-11 by Hoffman H, Swick B, Liu V, and Stone M. I. Definition of Spitz Nevus. A benign melanociytic proliferation that in some cases (atypical spitzoid lesions) can exhibit clinical and histologic features that resemble melanoma
A Spitz nevus is a benign lesion that most commonly develops in pediatric patients. A Spitz nevus classically present as a rapidly growing pink papule or nodule, and it can be challenging to distinguish it clinically and histologically from melanoma, resulting in significant controversy about the best management approach Nevus is a general term that refers of any kind of skin lesion appearing after birth. Every epidermal and dermal component has the potential to proliferate in an abnormal fashion forming a nevi. Spitz nevus is a member of the melanocytic nevi group, which are benign collections of melanocytes in the skin.Although rare, there is theoretically a risk of transformation into melanoma Spitz nevus: Spitz nevus or epithelioid cell nevus is a pink (classic Spitz) or brown (pigmented Spitz) dome-shaped mole that arises in children and young adults. Reed nevus: Reed or spindle cell nevus is a very dark-colored mole with spindle-shaped dermal melanocytes, usually found on the limbs Spitz nevus (spindle and epithelial cell nevus) is a benign melanocytic nevus that classically appears as a < 5-6 mm dome-shaped, symmetric, smooth, pink to red papule on the head, neck, or extremities. In adults, these lesions may appear as deeply pigmented, red-brown, or dark brown in color
