AbstractAdenolipoma of the breast is a rare tumor classified as a hamartomatous lesion. It is a well-circumscribed lesion composed of adipocytes and other breast tissues. The characteristic feature is a well-circumscribed mass containing radiolucent fat admixed with dense fibrous connective tissue surrounded by a thin radiopaque pseudo capsule. Microscopically, there is a mixture of ducts and lobules with adipose tissue. Ductal hyperplasia, adenosis, calcification, and apocrine metaplasia may occur within the hamartoma. These are rarely associated with malignancies and excision is considered curative. If these lesions are not detected clinically or radiologically, these remain unrecognized. Awareness of this poorly recognized benign entity would help avoid an incorrect diagnosis and unnecessary intervention. Here we present a case of a 35-year-old female diagnosed histologically as adenolipoma of the breast.
