Clear cell neoplasms of the abdominal organs are represented by a variety of epithelial and mesenchymal neoplasms, of varying malignant potential. Several varieties of clear cell carcinomas, including those with tubulopapillary, hepatoid, colloid, or neuroendocrine features, have been described, as well as several benign epithelial neoplasms. These epithelial tumors have been reported in the gastrointestinal hollow viscera, as well as the liver, pancreas, and billary tract. A second major consideration is the mesenchymal-derived gastrointestinal stromal tumors which also may feature clear cells, and comprise a spectrum of biological behavior. Miscellaneous los OhS include clear cell variants of melanoma and mesothelioma. This review includes histological details of the various entities, as well as important histochemical, immunohistological, and ultrastructural features. Pertinent differential diagnostic points are stressed, including distinction of the primary clear lesions from relevant metastatic neoplasms.
