A 10‐year‐old boy had multiple papules after surgery on a primary lesion on his left ear. The papules were pink and showed a linear arrangement around the helix. Histopathological examination of two separate lesions showed proliferation of epithelioid cells in the dermis and some of them formed nests. No melanin was found in the epithelioid cells, and immunohistochemistry staining with S100, HMB45 and Melan‐A were positive in the neoplasm cells. According to the clinical and histopathological characteristics, it was diagnosed as hypopigmented Spitz nevi with linear arrangement after trauma.
