Nevus definition, types, diagnosis & nevus treatment

The histopathologic distinction between Spitz nevus and Reed nevus is often matter of great debate. Nowadays, we distinguish two clinical variants of SN, the classical and the pigmented types, the latter include Reed nevus. The most important issue of SN is their propensity to mimic melanoma clinically, dermatoscopically and histopathologicallly.


Reed Nevus (Pigmented Spindle Cell Nevus) in an 11MonthOld Japanese Infant

Pigmented spindle cell nevus (PSCN) of Reed is a morphologic variant of Spitz and may be very diagnostically challenging, having histologic features concerning for melanoma. Their occurrence in younger patients, lack of association to sun exposure, and rapid early growth phase similar to Spitz nevi suggest fusions may also play a significant.


Dermoscopy Made Simple Reed Nevus

The Reed Nevus or pigmented spindle cell nevus (PSCN) was first described by Reed et al. in 1975 . Its designation as a separate entity vs. a SN variant remains controversial, but is currently considered by the 2018 WHO Classification to be a "distinct variant of Spitz naevus.".

Pigmented spindle cell nevus is a benign melanocytic lesion that was initially described in 1975 by Reed et al. It is generally found on the trunk or lower extremities of young women. Most authors consider it to be a variant of Spitz nevus. The main concern with these lesions remains their propensity to mimic melanoma both clinically and histologically.

Differential diagnosis of Spitz and Reed naevi. The differential diagnosis of Spitz and Reed naevi includes acquired melanocytic naevi, blue naevi and melanoma.. Spitz tumours with kinase fusions. It has recently been shown that spitzoid neoplasms harbour kinase fusions of ROS1 (17%), NTRK1 (16%), ALK (10%), BRAF (5%) and RET (3%) in a mutually exclusive pattern.


Pigmented Spindle Cell Nevus of Reed Dermatopathology

Reed naevus; Meyerson naevus is a naevus affected by a halo of eczema / dermatitis. Halo naevus or Sutton naevus has a white halo around the mole. The mole gradually fades away over several years. Spitz naevus or epithelioid cell naevus is a pink (classic Spitz) or brown (pigmented Spitz) dome-shaped mole that arises in children and young adults.


Pigmented Spindle Cell Nevus of Reed Dermatopathology

Reed nevus is composed histologically of elongated spindle-shaped and nevoid cells with a benign biologic behavior. Histopathological features in common with Spitz nevi and in contrast with malignant melanoma include a relatively small size, lesion symmetry, uniformity of cell type, good circumscription, and maturation of cells from superficial.

The Spitz naevus (syn. spindle cell naevus, epithelioid cell naevus, juvenile melanoma) is a variant of a compound naevus and is most commonly seen in children . The pigmented spindle cell naevus of Reed (PSCNOR) is a variant of a compound or occasionally a junctional naevus. There is debate as to whether the PSCNOR is an entity in its own.


Starburst dermoscopic pattern of Reed nevus Download Scientific Diagram

Clinically, pigmented Spitz/Reed nevi are brown to black, flat to slightly elevated, symmetrical lesions showing a relative preference for certain locations, including face, limbs and buttocks. The most relevant and peculiar feature is the starburst pattern seen by dermoscopy. This is typified by multiple streaks of pigmentation or large.


Dermpath Made Simple Neoplastic Spitz Nevus and Reed Nevus

Reed nevus is considered a pigmented variant of Spitz nevus. It usually appears during childhood, adolescence or early adulthood, and commonly appears on the lower limbs of female patients. After 6 months of rapid growth, Reed nevus tends to show no more enlargements over time. The starburst pattern is the dermatoscopic hallmark of Reed nevus.


Dermpath Made Simple Neoplastic Spitz Nevus and Reed Nevus

Spitz naevus is classified as classic, pigmented, or spindle cell tumour of Reed. The classic Spitz naevus is typically a dome-shaped red, reddish-brown papule. A pigmented Spitz naevus is a tan or brown papule or nodule. A pigmented spindle cell tumour of Reed is a bluish or black papule. There are clinical features in common for all three.

Symmetric with cytologic maturation. Nests and fascicles of spindled melanocytes along dermoepidermal junction and within dermal papillae. May be junctional or compound. Expansive, not infiltrative growth pattern. Extends no deeper than reticular dermis. Nevus cells typically contain abundant melanin pigment, may be associated with melanophages.

In contrast to Spitz nevus, the indicators of a congenital origin of Reed nevus are poor. The outstanding reports on agminated or systematized Reed nevi, or Reed nevus as constituent of a combined nevus, rather suggest a histogenetic event compatible with what is regarded to be a truly acquired melanocytic nevus and might represent another clue.


Naevus van Reed (pigmented spindle cell nevus)

A Reed naevus is a very dark pigmented melanocytic naevus with spindle-shaped dermal melanocytes on histology. It was first reported by dermatologist Richard Reed in 1975. It is also known as a spindle cell naevus. Reed naevus is sometimes classified as a kind of Spitz naevus; the spindle-shaped cells of the Reed naevus may coexist with the.
