Nodular hidradenoma: an eccrine sweat gland analog of pleomorphic adenomas of salivary gland origin.
A tumor of eccrine sweat gland origin is described that bears a striking resemblance to pleomorphic adenomas of salivary gland. Upon closer examination, the tumor contained areas of apocrine decapitation secretory activity, primitive hair follicles, and melanin pigmentation, indicating cutaneous rather than mucosal origin. Six-month follow-up examination has revealed no evidence of recurrence.
