Abstract

|
Pigmented spindle cell nevus (PSCN) is a solitary heavily pigmented macule or papule that usually occurs on the lower legs of women in the second decade of life. Histologically, fascicles of uniform, elongated, pigmented nevoid cells at the dermo-epidermal junction tend to fuse with neighboring nests. PSCN should be differentiated from Spitz nevus, dysplastic nevus, and malignant melanoma. For making the differential diagnosis of PSCN from malignant melanoma of nevoid cells, the overall symmetry, relative uniformity, maturation with depth and no nuclear atypia are important clues. A 3-year-old girl presented with a black papule on the anterior aspect of the ankle. We diagnosed PSCN by the histologic findings and the specific “starburst” dermoscopic pattern.
