Phyllodes tumors are an uncommon differential diagnosis of axillary mass

AbstractPhyllodes tumors are rare fibroepithelial neoplasm that account for less than 0.5% of all breast tumors and presentation in ectopic breast tissue is even rarer. In this paper, we describe a case of a phyllodes tumor in the ectopic breast tissue of the axilla. A 40-year-old woman presented with a well-circumscribed, firm, and freely mobile mass in the left axilla from 1  year ago. Ultrasound revealed a 5.5 × 4.5 × 4.5 cm homogenous and hypoecho lesion. The histopathologic analysis revealed that it was a benign phyllodes tumor. Phyllodes tumors in ectopic breast tissue may be confirmed to be a diagnostic difficulty, and this concept must be kept in mind whil e dealing with an axillary mass.
