Unusual presentation of a case of intra cystic papillary carcinoma of breast

The term “intra cystic papillary ductal carcinoma in situ”, has recently changed and is now more appropriately referred to as “intra cystic papillary carcinoma'' constituting only 0.5% to 1% of all breast cancers. Herein, we discuss an unusual case of intra cystic in situ papillary carcinoma of breast in a postmenopausal woman, the diagnosis of which was made on histopathology. So careful histopathological evaluation is the mainstay to arrive at the correct diagnosis to avoid untoward complications related to under diagnosis and/ over diagnosis.
