An unusual presentation of a severely calcified parasitic leiomyoma in a postmenopausal woman.

We report the case of a calcified parasitic leiomyoma in a 51-year-old postmenopausal woman with lower abdominal discomfort. She had no history of surgery. Workup confirmed a calcified leiomyoma. On laparoscopy, the mass was separate from the uterus and adhered to the bowel and bladder. Histopathological examination confirmed a calcified leiomyoma. A calcified parasitic leiomyoma in a postmenopausal woman is rare. Most prior cases were in persons with a history of a laparoscopic myomectomy. The diagnosis can be made by radiological findings. Laparoscopic excision is the treatment of choice in such cases.

Borderline-like mucinous tumor arising in mature cystic teratoma of the ovary associated with pseudomyxoma peritonei.

SUMMARY: Pseudomyxoma peritonei (PMP) is now considered to originate from appendiceal mucinous neoplasms in almost all cases. However, a mucinous neoplasm arising in a mature cystic teratoma is rarely responsible for PMP. We herein report 2 cases of PMP associated with borderline mucinous tumors arising in mature cystic teratoma. Both ovarian borderline mucinous tumors were morphologically and immunohistochemically similar to the secondary tumors from appendiceal origin, and PMP was histologically similar to peritoneal adenomucinosis.
