Pigmented Spindled cell nevus of Reed Reed Nevus 2 Reed Nevus This nevus is typically very dark with characteristic lines radial peripheral or streaks around the periphery under the dermatoscope. It is a worrying looking lesion clinically, often seen in younger individuals in their teens or twenties but is reasonably easy to diagnose under the microscope.

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. Nevus cells typically contain abundant melanin pigment, may be associated with melanophages. Nuclei are monotonous, resemble normal keratinocytes and may have small nucleoli. Often has architectural or cytologic atypia ( Hum Pathol 1991;22:52 ) Variable lymphocytic infiltrate at base of lesion. Pigmented Spindle Cell Nevus (Reed) is a benign, darkly-pigmented skin lesion that chiefly forms on the upper and lower limbs.

Pigmented spindle cell nevus Many dermatopathologists believe the pigmented spindle cell nevus (PSCN) of Reed, or Reed’s nevus, represents one end of the spectrum of Spitz nevi, composed exclusively of spindled cells with the aforementioned spitzoid cytomorphology. These lesions

They’re sometimes called 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.

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 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.

Reed Nevus at Low Magnification Histologic examination of a Reed nevus shows fusion of rete ridges by a proliferation of junctional pigmented spindle cells, which show a characteristic streaming together pattern. 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.
