Dermoscopy of Pigmented Spitz and Reed Nevi Dermatology JAMA Dermatology The JAMA Network
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.
Pigmented Spindle Cell Nevus of Reed Dermatopathology
Reed nevus (also known as pigmented spindle cell nevus of Reed) is an acquired, benign, melanocytic lesion most frequently classified as a variant of a Spitz nevus. A Reed nevus typically presents as an asymptomatic, single, 2-8 mm, dark brown to black macule or papule on the lower extremities of young adults. The lesion may also be found in.
Dermpath Made Simple Neoplastic Spitz Nevus and Reed Nevus
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.
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.
Dermoscopy of Pigmented Spitz and Reed Nevi The Starburst Pattern Dermatology JAMA
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.

However, to date, many textbooks or atlases of dermatology or histopathology assert that Reed nevus is a variant of Spitz nevus [4,6,21-25]. According to Argenziano et al, a dermatopathologic distinction between pigmented Spitz and Reed nevus is difficult, not reproducible and maybe clinically useless.
Reed Nevus (Pigmented Spindle Cell Nevus) in an 11MonthOld Japanese Infant
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.
Dermoscopy of Pigmented Spitz and Reed Nevi The Starburst Pattern Dermatology JAMA
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.

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.
Dermoscopy Made Simple Reed Nevus
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.
Starburst dermoscopic pattern of Reed nevus Download Scientific Diagram
The clinical-dermatoscopic-histological correlation of excised Spitz/Reed nevi revealed overlapping histopathological features among lesions displaying distinct dermatoscopic patterns ( Figures 1 - 3 ). Among lesions with histopathological atypia (16/47, 34.0%), all dermatoscopic patterns were represented, although the atypical/multicomponent.
Pigmented Spindle Cell Nevus of Reed Dermatopathology
A Reed nevus is a dark brown or black, raised, dome-shaped mole that most often affects women. These moles can grow quickly and may be mistaken for melanoma. These moles can grow quickly and may.

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 (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.
Nevus definition, types, diagnosis & nevus treatment
'Nevus, Reed' published in 'Dermatopathology' Pigmented spindle cell nevus is a sharply demarcated and symmetrical melanocytic lesion characterized by a florid and cellular junctional component and marked melanin pigmentation (Fig. 1).The junctional aspect is composed of large and prominent nests containing uniform, spindled melanocytes arranged in fascicles with a characteristic vertical.
