A woman in her early 20s presented with a huge pedunculated tumour of the vulva which had progressively increased in size over the course of 10 years. Clinical examination revealed a pedunculated solid mass arising from the right labia majora measuring 15×15 cm. CT scan showed a multilobulated mass arising from the right round ligament suggestive of an extrauterine fibroid. Tumour excision, vulvoplasty and inguinal repair were performed, and histopathological examination confirmed fibroid of lipoleiomyoma variant. This article reports a rare case of round ligament fibroid presenting as a huge pedunculated vulvar tumour.
