A clinicopathological and immunohistochemical profile of primary extra mammary paget's Disease in skin of colour: A case series

Abstract

Extramammary Paget's disease is an intraepithelial neoplasm, usually found in areas rich in apocrine gland concentration. The clinical features, histopathology, immunohistochemistry and management details of five patients (F = 3, M = 2) have been described here. While a well-defined persistent plaque with crusting and erosion was the most common presentation, hyperpigmentation, hypopigmentation and depigmentation were also observed in two patients. Characteristic Paget's cells with cytokeratin 7 and EMA positivity were seen on histopathology examination. Authors conclude that pigmentary alterations may be under-reported in extra mammary Paget's disease in the skin of colour.
