Bilateral multiple axillary apocrine hidrocystomas accompanied by apocrine hyperplasia: a rare presentation.

Apocrine hidrocystomas (AHC) are uncommon cystic lesions of apocrine glands and are most often solitary. They are usually found in the head and neck region. Multiple AHC have been rarely reported in the literature usually in the eyelids and face. On extensive search of literature, we came across only a single case report of multiple axillary AHC. We report a case of a 31-year-old female who presented with fullness and discomfort in bilateral axillae, so a clinical diagnosis of bilateral accessory breast was made. However on histopathological examination, it turned out to be bilateral multiple AHC associated with apocrine hyperplasia.
