A small cell carcinoma associated with an ordinary adenocarcinoma (mixed type tumor) of the gallbladder in a 49-year-old man is presented herein. Macroscopically, the gallbladder showed an annular, diffuse thickening of the body and fundus. The commonbile duct distal to the cystic duct was also segmentally constricted by infiltration of carcinoma. Microscopically, the tumor of the gallbladder was composed of two neoplastc components; an ordinary adenocarcinoma and a small cell carcinoma. The ordinary adenocarcinoma replaced the mucosa with invasion to the muscularis, while the small cell carcinoma revealed extensive spread with vascular invasion into the commonbile duct. Both tumors were partially intermingled with occasional transitional zones. Following pancreaticoduodenectomy, the patient had been placed on adjuvant chemotherapy, however expired with clinical manifestations of recurrence of carcinoma five months after surgery.
