Abstract

We report a case of amelanotic melanoma(AMM) in a 53-year-old man who presented a single, 1.5×1.5cm sized, well-demarcated, bright red nodule with erosion on the right heel for 9 months. Histopathologic findings showed irregular junctional activity in the epidermal-dermal junction and alveolar formation in the dermis. The majority of the tumor cells were seen as bizarre and giant cell of epithelioid type with atypical mitotic figure. We could not find melanin pigment in H & E stain.
