title: Invasive papillary carcinoma of the breast presenting as post-traumatic recurrent hemorrhagic cysts.
abstract: We report the sonographic features of an intracystic papillary carcinoma of the breast presenting as recurrent hemorrhagic cysts following trauma. A 56-year-old woman presented with palpable breast masses after a traumatic event; sonography showed multiple, well-defined, hemorrhagic cysts. Hemorrhagic fluid was evacuated by fine needle aspiration with no residual lesions. Cytology was negative for malignancy. Five months later, the mass reappeared; sonography demonstrated multiple cysts with solid nodules. US-guided core biopsy and surgery revealed invasive papillary carcinoma. We suggest close follow-up of cystic masses, even with negative cytology, and performance of surgical excisional biopsy in cases of rapid refilling after aspiration.
