- Leiomyoma is commonly found in the female genital tract, but occurrence in the urinary bladder is very rare with only 235 cases reported in the literature. These tumors have been classified as intravesical (63%), intramural (7%) and extravesical (30%) depending on the direction of the growth.
We report a case of intravesical leiomyoma of the urinary bladder in a 36 year-old woman who exhibited dysuria and urinary retention. The gross and microscopical findings of leiomyoma of the bladder are similar to those of the uterus.
Immunohistochemical stains for estrogen receptor (ER) and progesterone receptor (PR) revealed diffuse nuclear staining in smooth muscle cells, supporting the hypothesis of hormonal influence in tumorigenesis.

Abstract
PDF
- Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman.
Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter.
On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials.
Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.
