Malignant Nodular Hidradenoma- A Distinctly Rare and Diagnostically Challenging Sweat Gland Tumor

Abstract

Malignant Nodular Hidradenoma otherwise designated as Hidradenocarcinoma is a malignant sweat gland tumor which mandates attention due to its rarity and its increased potential for local destruction and metastasis. Though it was first reported in 1954, only 70 cases have been documented till date as per review of literature. The tumor possesses distinctive histological and immunohistochemical features with definitive criteria designed for detection of malignancy. This case report describes the occurrence of malignant nodular hidradenoma in a 40 year old male on the dorsum of the left foot.
