Numerous mature squamous cells are not found in the ascites. There have been no reported cases in which mature squamous cells were found in the ascites at laparotomy. We have experienced a case of immature teratoma associated with endodermal sinus tumor of the ovary which had numerous mature squamous cells in the ascites.<BR>The patient, a 14 year-old girl, was admitted to our hospital because of abdominal distension. Upon opening the abdomen, intraperitoneal cavity was filled with a giant left ovarian tumor and 300ml of yellowish ascitic fluid was aspirated. Cytological examination of the ascitic fluid disclosed numerous superficial, intermediate and parabasal squamous cells which had no atypia among small numbers of neutrophils in a clean background. There were no other tumor cells. Histologically, most of the mass was mature teratoma but partially immature neural tissue and endodermal sinus tumor. After chemotherapy for nine months, a second look operation was performed. Gliomatosis peritonei was only found in the peritoneal cavity. There was no evidence of recurrence and no squamous cells in the washing cytology.<BR>We concluded that the numerous mature squamous cells were derived from the ruptured immature teratoma, in particular parts of mature squamous tissue. These cells were not found at the second look operation.
