Malignant mixed tumor (carcinosarcoma) of parotid gland diagnosed by fine-needle aspiration biopsy.
True malignant mixed tumor (carcinosarcoma) of salivary gland is a very rare neoplasm. Only one brief account of the Fine-Needle Aspiration Biopsy (FNAB) cytologic findings of this tumor was found in the literature. The authors report a case of malignant mixed tumor (chondrosarcoma and epidermoid carcinoma) arising from the left parotid gland in an 84-yr-old man, which was definitely diagnosed by FNAB. The cytologic findings and differential diagnosis are discussed.
