A case of carcinoma of the vulva arising in condylomata acuminata is presented. The patient was much younger than is classically reported for carcinoma of the vulva. The vulvar growth was first noted during pregnancy, and it continued to grow and enlarge following delivery. Malignancy appeared to develop after a relatively short time. It is sometimes difficult to distinguish vulvar condylomata acuminata from carcinoma from clinical evidence alone. It is, therefore, mandatory in doubtful cases to take multiple biopsies from the lesion before treatment is instituted.
