Vulval lymphangiectasia.

Three cases of lymphangiectasia of the vulva are reported. One case followed Wertheim's hysterectomy for carcinoma of the cervix; two other cases had Crohn's disease with perineal involvement. Lymphangiectasia is a secondary phenomenon resulting from obstruction of previously normal lymphatics. This is in contrast with lymphangioma which is an anatomical abnormality. A review of the literature suggests that the vulval skin may be particularly susceptible to the formation of lymphangiectasia, and our patients' experiences suggest that they are easily mis-diagnosed.
