Reed nevus or pigmented spindle-cell nevus was first described by Reed in 1975. Pigmented spindle cell nevus is regarded as a distinct entity and not part of spindle cell variant of Spitz nevus. Clinically, these lesions present as symmetrical, sharply circumscribed, darkly pigmented nodule or papule (usually less than 0.6 cm in diameter).

Reed Nevus With Junctional Nests Showing Bridging Higher magnification shows bridging across rete ridges by junctional nests of streaming pigmented spindle-shaped cells. 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. Reed nevus or pigmented spindle-cell nevus was first described by Reed in 1975.

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 role in these lesions. Pigmented spindle cell naevus of Reed. The pigmented spindle cell naevus of Reed (PSCNOR) is a variant of a benign melanocytic naevus. There is debate as to whether the PSCNOR is an entity in its own right or whether it is a variation of a Spitz naevus. 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, also pigmented spindle cell nevus of Reed and Reed nevus, is an uncommon benign melanocytic lesion. 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.

Show diagnosis & comments. Diagnosis: Pigmented spindle cell naevus (Reed at the edge of a given pigmented skin lesion. Diagnostic significance. The starburst pattern is stereotypical for Reed nevus, although a certain variability of this.

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. Reed or spindle cell naevus is a very dark-coloured mole with spindle-shaped dermal melanocytes, usually found on the limbs. ABSTRACT Background/Objectives: The Reed naevus or pigmented spindle cell naevus of Reed (PSCN) was previously considered a pigmented variant of the spindle cell‐type of Spitz naevus. It is now co Spitz and Reed nevi, also called spindle and/or epithelioid cell nevi, are a special group of melanocytic lesions due to their peculiar clinical, dermoscopic and histopathological features.
