Nodular hidradenoma: A worrisome mass lesion

Nodular hidradenoma is a benign neoplastic lesion of the sweat gland which is rare in its occurrence. It commonly occurs in the upper trunk and extremities. Complete excision is the only surgical treatment and avoids recurrence. We herein report a case of nodular hidradenoma that presented as a right shoulder lump in a middle-aged woman. Clinical and radiological struggles were futile to establish a definitive diagnosis of this lesion. However, histopathology of the excised tumor unveiled the diagnosis of nodular hidradenoma.
