RARE CASE OF TRANSITIONAL-CELL CARCINOMA ORIGINATING IN BARTHOLINS-GLAND DUCT

We report a rare case of papillary invasive transitional cell carcinoma (TCC) that originated in Bartholin's gland duct. It resulted in differentiation into low-grade dysplasia and grade-ill invasive TCC. Because invasive lesions within the lamina propria developed from flat dysplasia, the invasive TCC had presumably progressed from low-grade dysplasia. To our knowledge, 6 cases of TCC originating in Bartholin's gland have been reported previously, but our report is the first to describe TCC associated with dysplasia. The progressive course of this rare carcinoma is discussed.
