Cystic mesothelioma of the peritoneum is a rare benign neoplasm that occurs predominantly in young to middle-aged women and tends to recur locally. Pelvic viscera is the most common predilection site of cystic mesothelioma. Authors report a case of multicystic mesothelioma of the pelvic pelvic peritoneum. The pelvic ultrasonography showed a large, confluent, and thin-walled multilocular cystic mass occupying the pelvic cavity and lower abdomen. The cystic mass was flattened and elongated. Each cyst of variable size was separated by thin septa and filled with translucent fluid. Cystic mesothelioma should be included in the differential diagnosis of the cystic peritoneal masses, especially in reproductive-aged women.

Arteriovenous Malformations*

Arteriovenous malformation of the pelvic organ is a very rare cause of massive uterine bleeding. But, it is important to consider in the assessment of a patient with abnormal uterine bleeding because accurate diagnosis can allow appropriate treatment to be planned and avoid hysterectomy in women who wish to retain their reproductive capacity. This malformation may be congenital or acquired. In the past, the diagnosis is usually made retrospecively after hysterectomy, however, recently it may be made before management by ultrasound, doppler ultrasound, pelvic angiography, magnetic resonance imaging, etc. We have experienced two cases of arteriovenous malformation of the uterus, which is presented with a brief review of the literatures.

Mature cystic teratoma of the ovary is the most common ovarian germ cell tumor and almost benign, but malignant transformation occurs in less than 2% of benign mature teratoma. Of the malignancies arising in teratomas, squamous cell carcinoma is the most common (70-80%). The presentation in stage I disease dose not differ from that of benign cystic teratoma. In the early stage, the treatment is possible through surgical intervention alone. We experienced a case of squamous cell carcinoma of the ovary arising in mature cystic teratoma, which is presented with a brief review of literature.
