title: Malignant mixed tumor of the gallbladder.
abstract: Multimorphic malignant tumors containing elements of two or more germ layers presenting as mixed tumors are rarely encountered in the gallbladder. A review of the literature revealed a report of a single case in which the histologic appearance was similar to that of the case reported herein. The malignant mixed tumor of the gallbladder appears to be a highly anaplastic and rapidly fatal neoplasm. It may be suspected by the presence of chondroid or myxoid tissue, or both, on gross examination.
