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.

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.

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.

PURPOSE: A laparoscopic cholecystectomy is now the gold standard for the treatment of gallstone disease. While the widespread use of ultrasonography has increased the frequency of the diagnosis of polypoid lesions of the gallbladder (PLG), no optimal strategies for evaluating and treating these lesions have been established. The aims of this study were to identify the risk factors for malignancy, and evaluate the usefulness of laparoscopic cholecystectomy for PLG. METHODS: The clinical and histopathological data from ninety PLG patients, who received a laparoscopic cholecystectomy, between January 1998 and December 2005, were retrospectively analyzed. Data were evaluated using a multiple logistical regression analysis. RESULTS: There were 82 benign PLG, including 38 cholesterol polyps, 22 adenomas, 18 hyperplastic polyps and 4 adenomyomas, and 8 malignant PLG. The average age of the patients with malignant PLG was significantly older than that of those with benign PLG (P=0.001). The average malignant PLG diameter was significantly larger than that of the benign PLG (P=0.000). The malignant PLG were mostly a single lesion; whereas, half of the benign PLG were multiple lesions. In the multiple logistical regression analysis, polyp sizes greater than 1.5 cm and an age over 50 years were the two most important factors for predicting malignancy of PLG. Seven of eight patients with malignant PLG are still alive at a mean of 43.8 months after surgery, and without any recurrence. CONCLUSION: The risk factors for malignancy were found to be the polyp size and patient age. A laparoscopic cholecystectomy can be considered an adequate treatment for patients with a stage I gallbladder carcinoma.

Adenomyoma is a non-neoplastic tumor-like lesion that frequently occurs in the gallbladder (GB), but it is very rarely seen in the Vaterian ampulla. The pathological findings of adenomyoma are characterized by the lobule containing hyperplasia of the smooth muscle cells and ductal or glandular structures. This tumor is clearly a benign disease. However, when it develops in the Vaterian ampulla, it may be mistaken for a periampullary malignancy and could be treated with extensive surgery such as pancreaticoduodenectomy (PD). We have experienced a case of adenomyoma of the Vaterian ampulla. The patient was a 69-year-old male who developed mild hyperbilirubinemia as an initial symptom. The preoperative radiologic and endoscopic findings suggested a periampullary mass, but we could not differentiate whether it was benign or malignant. PD was performed and adenomyoma was diagnosed by pathological examination after the surgery.
