Abstract
We reported a newborn case of vaginal polyp with imperforate anus. After histological diagnosis of the vaginal polyp by biopsy the polyp was removed at second day. The tumor was botryoid shape and dark-red so that it diagnosed as sarcoma botryoides. The size of the polyp was 1.7×3.2×1.5cm and histological findings showed hamartomatous lesions which consisted of squamous epithelium, stromal fibrous tissue, hemangiomatous portions, scattered young muscle fibers with striations and so on. For six months after resection the baby has been well without recurrence.
