A case of labial adhesion due to lichen sclerosus et atrophicus.

A 67-year-old Japanese woman first visited to the hospital in regard to episodes of a 6 months history of difficulty on urination. Her perineum was mild whitish, and labia majorae were all adhered with only a pinhole-sized opening. A labial incision was performed under a spinal anesthesia. Pathological finding of the skin biopsy specimen was lichen sclerosus et atrophicus (LSA). In view of that LSA occasionally develops into squamous cell carcinoma, urologists should be care of LSA in labial adhesion case.
