Clear-cell carcinoma of the anal canal: a variant of anal transitional zone carcinoma.
Optically clear cytoplasm in tumor cells in the absence of mucin is most often associated with renal cell carcinoma. However it is important to recognize the rare occurrence of "clear-cell" variants among tumors arising in other sites. This report describes a clear-cell carcinoma arising in the transitional zone of the anal canal.
