Barcaui Medicine 2018-12-13 pigmented spindle cell nevus (reed nevus) Pigmented spindle cell nevus, a benign, heavily pigmented lesion, is considered a variant of Spitz nevus. It is more commonly seen in young adults (average age 22–years; range 3–5–years), has a female predominance (male-to-female ratio 1:4.5), and typically presents on the lower extremities and trunk. In Reed nevus, junctional cells are thin, elongated, pigmented and fusiform.
