Abstract

We report here on a rare case of sarcomatoid carcinoma that contained an epithelial component of squamous cell carcinoma. A 77-year-old woman was found to have a gallbladder mass. The gallbladder showed a diffuse infiltrative wall mass with a polypoid lesion, and the mass measured 8x7x3 cm. There were no gallstones. Histologically, the tumor was composed of two components of squamous cell carcinoma and spindle cell malignancy. The tumor extended to the perimuscular connective tissue and one regional lymph node. The postoperative course was uneventful and the patient was well without tumor recurrence at one and a half months after surgery.
