Abstract:
A 6-year-old boy presented with a fast-growing, 0.8x0.7 cm-sized, dome-shaped, erythematous nodule on the back. Histopathologically, the lesion showed a spitzoid melanocytic proliferation from the dermo-epidermal junction to the reticular dermis. Melanocytes arranged in nests were epithelioid and spindle-shaped with abundant eosinophilic cytoplasm. The histopathological and clinical features were consistent with atypical Spitz nevus in that they showed no Kamino body, prominent cellular density, more than three mitoses per high power field, a high Ki-67 level, large size, and the lesion was located at an unusual location. Herein, we report a case of an atypical Spitz nevus on the back of a 6-year-old boy.
