Combined small cell carcinoma and clear cell carcinoma of the gallbladder: report of a case and review of the literature.
We report a case of an incidental combined carcinoma of the gallbladder in a 66-year-old woman who underwent cholecistectomy for gallstones. The neoplasm was mainly constituted by a clear cell component and a small cell, chromogranin-positive one; it also showed some areas of conventional adenocarcinoma and foci of vascular invasion. The patient died after 3 years following treatment with combination chemotherapy. The histologic and immunohistochemical profile of the lesion is described, together with a brief review of the pertinent bibliography.
