Intracystic papillary carcinoma of the breast: report of two cases.
ABSTRACT Intracystic papillary carcinoma (IPC) of the breast has traditionally been considered to be a variant of ductal carcinoma in-situ (DCIS). It is an uncommon tumor accounting for less than 3% of all breast cancers and predominantly affects elderly women. IPC is extremely rare in men and only few cases have been reported in the literature. The tumor has excellent prognosis regardless of whether it is in-situ or invasive. Hence an accurate diagnosis plays a crucial role in the management of patients with IPC. We report two cases of IPC, one in a 68-year-old woman and the other one in a 70-year-old man. The diagnosis was suspected on fine needle aspiration cytology (FNAC) and was confirmed by histopathology.
