Epidermotropic metastatic melanoma with perilesional depigmentation in an Indian male

Abstract

Melanoma is a rare form of cutaneous malignancy encountered in the dark skin population. Epidermotropic metastatic melanoma is a rare form of cutaneous metastatic melanoma which can mimic primary melanoma on histopathology. Hence its differentiation is of immense prognostic importance. The occurrence of rim of depigmentation around the primary cutaneous melanoma has previously been reported to portend a bad prognosis. The occurrence of vitiligo like lesions in patients with metastatic melanoma in comparison has a better prognosis. However the occurrence of depigmentation around the secondaries is rare and its importance is not well known. Hence we wish to report a case of epidermotropic metastatic melanoma with perilesional depigmentation in a 78 year old Indian male.
