RESUMO
Warthin tumor is a well-recognized benign salivary gland neoplasm consisting of an epithelial as well as a lymphoid component. Malignant transformation in Warthin tumor is rare and its reported incidence is up to 1%. The more common types of carcinomas described in Warthin tumor are the squamous and mucoepidermoid types, with high-grade adenocarcinoma being extremely rare. A high-grade adenocarcinoma (ductal type) arising in the Warthin tumor in a 72-year-old man is presented for its rarity and diagnostic difficulties.

Primary hepatic carcinosarcoma is a rare tumor comprised of a mixture of carcinomatous and sarcomatous elements. Less than 20 adequately documented cases have been reported, however the imaging features of two cases were briefly described. We present here a case of carcinosarcoma of the liver in a 46-year-old woman, which was confirmed based on pathology. Imaging showed a large mass with large necrotic portions, small cystic portions, calcifications and bone formations.
