RESUMO
Clear cell basal cell carcinoma is an uncommon histologic type, which is characterized by various vacuoles filled with glycogen in a clear cell mass. Vacuoles often cause peripheral displacement of the nucleus. We report a case of clear cell basal cell carcinoma in an 81-year-old woman who had suffered from 0.5cmx0.5cm solitary hemorrhagic ulcerative nodule for 1 year. Surgical excision was done and no recurrences were found.

Clear cell basal cell carcinoma(BCC) is an unusual variant of BCC which is characterized by a variable component of large clear cells. Clear cell changes were displayed trichilemmal differentiation but recently are more consistent with degenerative phenomenon than that. We describe a case which clinically looked like superficial type BCC or Bowen's disease, presenting as a crusted eruption on the abdomen and histologically showed mixed clear cell BCC with distinct pagetoid infiltration of clear cells in the overlying epidermis.

Clear cell basal cell carcinoma (clear cell BCC) is a rare variant of BCC, which is characterized by variable proliferation of clear cells within the mass. We herein report three cases of clear cell BCC. Three old Korean men presented lesions as a solitary nodule on their face. Histologic examination showed multiple dermal tumor lobules composed of basophilic cells, clear cells and peripheral palisading with surrounding retraction spaces. The clear cells showed either a clear cytoplasm or eosinophilic granular cytoplasm, and contained glycogen. There were no recurrences after surgical excision.
