Sixty-five patients with carcinoma in situ of the vulva were reviewed. Attention was focused upon the epidemiology, duration of symptoms, and location of lesions. The vulva and perineum were divided diagrammatically into 16 geographic compartments; lesion location and percentage of occurrence in each area were calculated. The most common site was the inferior border of the right labium majus. Eighty-four percent of patients under the age of 40 had multifocal disease. Sixty-five percent of patients over 40 had unifocal disease.
