title: The cytology of micropapillary variant of colloid carcinoma of breast: A report of two cases.
abstract: Colloid carcinoma (pure mucinous carcinoma) is an uncommon variant of breast carcinoma with distinctive cytological and histological features. These tumors are characterised by islands of tumor cells floating in a sea of abundant extracellular mucin. We present the cytology of two cases of colloid carcinoma occurring in 80-year-old and 45-year-old females. The fine-needle aspiration cytology helps to subcategorize the tumor type, thereby enhancing the knowledge about the distinctive cytological features of special and uncommon variants of breast carcinoma, their course and prognosis. A distinctive micropapillary variant of pure mucinous carcinoma which is rarely described, is represented in one of the cases. Also we report, here, colloid carcinoma in a female of reproductive age, a relatively uncommon occurrence.
