An Intracystic Papillary Carcinoma of the Breast

Abstract intracystic carcinoma of the breast is a rare form of breast carcinoma. among all malignant breast tumors, this lesion has an incidence of 0.2-0.5%. these neoplasms have certain characteristic imaging findings which help to differentiate these lesions from other focal breast abnormalities.this report is on the case of a 48-year-old woman with a palpable, painless lump in her right breast. mammography demonstrated an oval well-circumscribed mass without calcification. breast ultrasonography showed a cystic lesion with an intracystic solid component projecting from its posterior wall. cyst aspiration revealed a hemorrhagic fluid and a suspicious cytology. excisional biopsy revealed papillary carcinoma suggesting of intracystic papillary carcinoma.
