Hidradenoma is a term that refers to a type of benign tumor that grows in the sweat gland. While this term is widely used in the medical field, there are a few other synonyms that can be used to refer to this condition. These synonyms include clear cell hidradenoma, eccrine acrospiroma, and nodular hidradenoma. These terms are all used to describe the same condition, although they may be used interchangeably depending on the preference of the healthcare professional. Patients with hidradenoma may experience a range of symptoms, including the appearance of small, painless lumps, which can be treated through surgical removal.
