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
A Spitz nevus is a type of noncancerous growth. In this article, learn about the types, diagnosis, and when to see a doctor to check for melanoma Spitz naevus. Spitz naevus may pose great diagnostic difficulty due to clinical, dermatoscopic and histologic features resembling melanoma.Though usually seen in children, Spitz naevi may arise in adults. The typical or classic lesion is a pink papule or nodule, which appears suddenly and grows rapidly for a few months.There is a pigmented variant.. The majority of Spitz naevi are compound or. Introduction . In 1948, Sophie Spitz described a group of melanocytic lesions of children, first considered as melanomas of childhood, and subsequently histologically categorized as benign melanocytic proliferations, then renamed as Spitz nevi. The majority of Spitz nevi occur in patients younger than 20 years and are less common in adulthood and elderly

Spitz naevus used to be called juvenile melanoma, but it's not really accurate to call it this
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 . Tumours are usually symmetrical and sharply defined. Hyperplastic epidermis with orthokeratosis, hyperkeratosis, hypergranulose and acanthosis. Typical cleavage between melanocyte nests and surrounding keratinocytes Spitz nevi usually arise de novo, but rarely can arise within a pre-existing melanocytic nevus or nevus spilus. What is the Cause of the Disease? Etiology. Spitz nevi are benign melanocytic proliferations; atypical Spitzoid tumors are melanocytic proliferations of indeterminate biological behaviour. Pathophysiolog
Spitz nevus, also known as epithelioid and spindle cell nevus, is an uncommon melanocytic lesion that can be difficult to differentiate from malignant melanoma 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). Less often, the lesions are pigmented or resemble other. Evidence-Based Clinical Decision Support at the Point of.
Dermoscopically, Spitz naevi are typified by three main patterns: starburst pattern (51%), a pattern of regularly distributed dotted vessels (19%) and globular pattern with reticular depigmentation (17%).

Background: There is no consensus concerning management of Spitz nevi. Objective: This study was carried out to ascertain how dermatologists manage Spitz nevi. Methods: A questionnaire was sent to 997 fellows of the American Academy of Dermatology, 284 pediatric dermatologists, and 27 directors of pigmented-lesion clinics. The results are based on the 381 questionnaires returned 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.

There are two main types of spitz naevi: 1) Classical spitz naevus is a rapidly growing pink papule/nodule on the face or limbs of a child or young adult. 2) Pigmented spitz (including spindle cell naevus of Reed) is again a rapidly growing brown or black papule or macule on the limbs of young adults. **Some melanomas can mimic spitz naevi and so most are managed with surgical excision** 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.

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 Nevus (plural nevi) is a nonspecific medical term for a visible, circumscribed, chronic lesion of the skin or mucosa. The term originates from nævus, which is Latin for birthmark; however, a nevus can be either congenital (present at birth) or acquired.Common terms, including mole, birthmark, and beauty mark, are used to describe nevi, but these terms do not distinguish specific types of.
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 Claim to Fame: Spitz Naevus Spitz naevus (also known as spindle and epithelioid cell naevus or juvenile melanoma) is a benign melanocytic compound naevus variant which is seen most commonly in children and which has distinctive histological features.. An uncommon lesion, accounting for less than 1% of all melanocytic naevi in children, it is usually seen in the first two decades of life.

The typical mole is a brown spot. But moles come in a wide variety of colors, shapes, and sizes Spitz nevus is named after Dr. Sophie Spitz, who in 1948 reported a case series of melanomas of childhood. [1, 2] Nearly all of Spitz's original series of 13 cases are now regarded as representing Spitz nevi, only 1 case having proved to be a melanoma resulting in metastasis and death.Historically, Spitz nevus has also been described under the headings of juvenile melanoma, benign juvenile.
Introduction. A Spitz nevus is a melanocytic neoplasm formed of epithelioid or spindle cells described for the first time by Darier and Civatte. 1 It was characterized in 1948 by Spitz using the term juvenile melanoma as a melanocytic tumor, present in childhood, with clinical and pathologic features similar to melanoma but with benign behavior. 2 Subsequently, it was found to affect all age. Spitzoid melanoma is the Scarlet Pimpernel of the melanoma tribe. It is elusive and histologically appears indistinguishable to benign skin lesions - Spitz Naevus, Haemangioma or Basal Cell Carcinoma. First catalogued in 1910 by Darrier and Civatte, they acquired their current name when Sophie Spitz, an America

It is frequently mistaken for a naevus undergoing malignant change
Abstract. The histological distinction between Spitz naevus (Spitz 1948) and a small group of melanomas which resemble Spitz naevus and which are therefore often referred to colloquially as Spitzoid melanomas (Smith et al. 1989; Chan et al. 1999) is notoriously difficult and may occasionally be impossible.In the past decades, the recognition of variants of Spitz naevus has resulted in a. 1.

Spitz naevus is an uncommon, benign melanocytic neoplasm that shares many clinical and histological features with melanoma. While Spitz naevi typically occur in children and melanomas typically occur in adults, either tumour can occur in a patient of any age. In cases displaying all or most of the classical histological features, particularly when occurring in a young patient, it is possible. Spitz naevus was first described by Sophie Spitz in 1948 (1). It is a variant of benign melanocytic naevus composed of spindled and epithelioid melanocytes, found predominantly in children and adolescents. A number of histopathological variants have been reported, such as desmoplastic, hyalinized, angiomatous, granulomatous, pagetoid, myxoid.
