Eccrine spiradenoma: A rare adnexal tumor

Abstract

Eccrine spiradenoma is one of the rare adnexal tumors with eccrine differentiation; however, it is considered to have apocrine differentiation. Around 50 cases of eccrine spiradenoma have been reported in the literature. Due to vascularity and painful symptoms, it is often confused with the painful lesions of skin such as glomus tumor and angioleiomyoma. Surgical excision is considered the gold standard for the treatment of these cases, with low rates of recurrence. Here, we present a 52-year-old male who presented with a nodular lesion in the left side of chest for the past 4 years. Surgical excision was performed and the tissue was sent for histopathological examination. Eccrine Spiradenoma may present congenitally or spontaneously as tumor of the sweat glands with unclear etiology. Early accurate diagnosis is very important in preventing chances of recurrence and more importantly identifying onset of malignant transformation.
