Gallbladder and extrahepatic biliary tract


Definition

A malignant neoplasm composed of glandular epithelial clear cells. Various architectural patterns may be seen, including papillary, tubulocystic, and solid.

Clear cell adenocarcinoma of the gallbladder
This rare malignant neoplasm is composed predominantly of glycogen-rich clear cells with well-defined cytoplasmic borders and central hyperchromatic nuclei arranged in glandular or other growth patterns

. Some cells contain eosinophilic granular cytoplasm. Foci of conventional adenocarcinoma with mucin production are usually found and can distinguish primary carcinomas from metastatic clear cell carcinomas of the kidney. Exclusion of renal cell carcinoma is also accomplished by immunohistochemical labelling for PAX8 and RCC

. In some clear cell adenocarcinomas, the columnar cells contain subnuclear and supranuclear vacuoles similar to those seen in secretory endometrium. Production of α-fetoprotein has been documented in clear cell carcinomas with or without hepatoid differentiation
