Adenosquamous carcinoma of the gallbladder

Between 1976 and 1987, 49 patients with cancer of the gallbladder were treated. In three specimens, histologic characteristics of adenosquamous carcinoma were detected, namely blasts deriving from both squamous and glandular epithelium. These carcinomas, relatively rare, are usually found in the gastrointestinal tract, the thyroid, the breast and the female genital apparatus.
