We diagnosed a 2-cm, large cystic adenomyoma after complete abortion without transcervical curettage, based on symptoms of dysmenorrhea, time of onset, and sonographic findings. The cystic adenomyoma was treated successfully with laparoscopic mass excision.

Adenomyoma is a benign tumor composed of smooth muscle and benign endometrium. These tumors typically originate within the uterus. An extrauterine adenomyoma is a rare entity. Cystic degeneration of adenomyoma is also very rare case. We report a case of huge extrauterine endometrioid-type adenomyoma with cystic change with brief review of literature.

The clinical and pathological features of an apparently unique case of an adenomyoitc cyst of the uterus are reported. The cyst was located within the myometrium of a 30-year-old woman suffering from vaginal bleeding for 6 months. Saline infusion sonohysterography revealed uterine cyst. After excision of the cyst, patient's symptoms improved. On histological examination, the cyst most closely resembled an adenomyotic cyst.

Adenomyoma is a nonneoplastic lesion that can be found anywhere in the gastrointestinal tract, but it's rarely found in the ampulla of Vater. To the best of our knowledge, it is a benign lesion, but most cases are misdiagnosed as carcinoma or adenoma by a preoperative endoscopic or radiologic procedure, and this leads to unnecessarily extensive surgical resection. We report here on a case of ampulla of Vater adenomyoma that resulted in biliary and pancreatic duct dilatation. The tumor was diagnosed by endoscopic papillectomy.

Adenomyosis is a common disease of middle-aged women and adenomyoma is a variety of adenomyosis that formed localized tumor. Cystic degeneration of an adenomyoma is a rare clinical manifestation. A 30-year-old parous woman suffered from severe dysmenorrhea and menorrhagia for about 5 months, was operated under the impression of endometriosis of the pelvis. Following the operation, cystic degeneration of an adenomyoma was found incidentally. The authors experienced a case of adenomyosis that formed cystic tumor of uterus and presented with a pertinent literatures.

A uterus-like mass (ULM) is a central cavity lined by endometrial glands and stroma and surrounded by thick-walled smooth muscles. To date, 31 cases of ULM have been reported in the English literature. ULM typically presents as a single mass and is located in the pelvic cavity. We report here a very rare case of multiple extrapelvic ULMs involving the cecum, descending colon, and mesocolon. After extensive literature research, our case appears to be the first case of multiple ULMs found in extrapelvic sites and the first case of ULM in the colon. The present case suggests that ULM should be included in the differential diagnosis of colonic submucosal tumors in female patients with chronic abdominal pain or menstruation-associated symptoms.

Adenomyoma, a benign tumor generally considered to be a form of pancreatic heterotopia, is composed of smooth muscle and undifferentiated columnar epithelium. A 62-year-old female was admitted with melena. Small bowel enteroscopy using a pediatric colonoscope revealed a small sized nodular mass with active bleeding in the proximal jejunum. After a endoscopic resection of the tumor, the bleeding ceased. Histologic examination disclosed an adenomyoma. We report a case of the adenom-yoma causing jejunal bleeding with a review of the literature.

Solid hamartoma of the pancreas is very rare, and only 3 cases have been reported thus far. A patient underwent pancreaticoduodenectomy due to a mass in the head of the pancreas which was suspected to be a borderline malignant tumor, but the histologic diagnosis turned out to be myoepithelial hamartoma (MEH) or adenomyoma. It was characterized by benign duct and glandular structures surrounded by proliferating smooth muscle, and acinus formation was not observed. Immunohistochemical stain for smooth muscle actin (SMA) was positive in spindle cells, and CD34 was negative, differentiating it from the three previously reported cases of solid hamartoma of the pancreas. MEH is an entity that is on the same spectrum as heterotopic pancreas. MEH is rare and has usually been reported in the gastrointestinal tract. To the best of our knowledge, MEH has never been reported in the pancreas. Therefore we report the world's first documented case of MEH of the pancreas.

Uterus-like masses, such as cavities lined by endometrium-type mucosa surrounded by bundles of smooth muscle cells, may strikingly resemble the uterus. In this report, we describe a case of a uterus-like mass with features of an extrauterine adenomyoma in a 42-year-old woman. The first uterine-like mass was documented by Cozzutto in 1981 and to date, 13 such cases have been reported. Three theories have been offered to explain their etiology: 1) the uterine/Mullerian duct fusion defect theory, which is based on a developmental abnormality occurring during the formation of the female genital tract, 2) the metaplastic theory, which is based on the fact that a uterus-like mass may arise from subperitoneal mesenchymal cells that retain the ability to duplicate Mullerian duct structures, and 3) the heterotopia theory. We consider that the metaplastic theory best fits with our observations in the present case as both glandular and stromal smooth muscle cells proliferated as a true neoplasm rather than as an anomaly.
