Cystic breast mass is one of the common conditions seen presented in any breast clinic. Evaluating such cystic breast lesions is very important. Malignant cystic tumors like mucinous carcinomas and papillary carcinomas have to be differentiated from common benign cystic lesions of the breast like fibrocystic lesions and papillomas. Malignant breast cancers that present as cystic lesions are seen to have a good prognosis regardless of histologic type. Among other malignant breast lesions that present as cystic masses, mucinous carcinomas are quite rare. Diagnosing cystic mucinous tumors is essential because of its prognostic significance.
