Dermoscopic classification of Spitz/Reed nevi
Section snippets
Clinical and histopathologic features
Clinical features consist in most cases of a solitary, asymptomatic, round to oval, dome-shaped papule or, less frequently, a plaque, a nodule, or a papillated polyp. The surface is commonly smooth or verrucous, and a scaly, crusted, or eroded surface is sometimes evident. There may be slow or rapid growth, color change, and rarely, bleeding or localized pruritus. The duration of the lesions ranges from weeks to years. A rapidly growing, pink-colored or reddish papule on the head and neck
Dermoscopic features
Clinical differential diagnosis of Spitz/Reed nevi may include either benign or malignant neoplasms, such as Clark nevus, dermatofibroma, angioma, granuloma pyogenicum, primary adnexal tumor, solitary mastocytoma, pseudolymphoma, and melanoma. In such instances, dermoscopic analysis has been shown to represent a useful technique to establish in most cases a definite diagnosis.15, 16, 17, 18, 19, 20, 21, 22, 23 An improvement of diagnostic accuracy of PSNs from 46% to 93% has been reported by

2014, Current Problems in SurgeryCitation Excerpt :Dermoscopy is a noninvasive form of in vivo microscopy and is helpful in distinguishing nonpigmented and pigmented SN from other entities in the differential diagnosis.17,66-71 The introduction of dermoscopy into clinical practice has improved the recognition of the morphologic spectrum of melanocytic tumors.59,60,72 Its use in children is ideal because it is painless and provides important information to the clinician for formulating appropriate management decisions.54
Problematic Lesions in Children
2013, Dermatologic ClinicsCitation Excerpt :However, a clinicopathologic evaluation of a large case series showed that the histopathologic distinction between these 2 diagnostic categories is often a matter of great debate.27 On dermoscopy, Spitz/Reed nevi can display 6 main dermoscopic patterns: vascular, globular, starburst, reticular, homogeneous, and atypical.27,31 The vascular pattern is mainly composed of dotted vessels,32,33 which are monomorphic, regularly distributed throughout the lesion, and surrounded by regularly intersecting white lines, the so-called “reticular depigmentation.”34

2011, Journal of the American Academy of DermatologyCitation Excerpt :The first is characterized by diffuse blue to black pigmentation that extends into radial streaks at the periphery, contributing to a stellate appearance. The second pattern consists of prominent brown to grey-blue pigmentation bordered by a peripheral rim of discrete pigment globules.31,32 Lesions may present an evolving dermatoscopic pattern from globular to starburst, and some may further change by losing the starburst pattern in favor of a homogeneous blue-brown pigmentation with or without central reticular pigmentation.33,34
