Biliary adenofibroma is a rare tumor with a bile duct origin characterized by a complex tubulocystic non-mucin secreting biliary epithelium with abundant fibrous stroma. The MRI features of biliary adenofibroma are not well established. The authors encountered two patients with biliary adenofibroma and reviewed the literature focusing on the MRI findings. A well-circumscribed multicystic tumor with septal enhancement and no intrahepatic bile duct communication may be the characteristic MRI findings of biliary adenofibroma.

Ovarian clear cell adenocarcinomas (CCACs) are frequently associated with endometriosis and, less often with clear cell adenofibromas (CCAFs). We encountered a case of ovarian CCAC arising from benign and borderline adenofibromas of the clear cell and endometrioid types with endometriosis in a 53-year-old woman. Regions of the adenofibromas showed transformation to CCAC and regions of the endometriosis showed atypical endometriotic cysts. This case demonstrates that CCAC can arise from CCAF or endometriosis.

OBJECTIVETo study the clinicopathologic features and differential diagnosis of recurrent Müllerian adenofibroma (MAF) of the uterus.

METHODSClinicopathologic information of 7 cases of recurrent MAF of uterus was retrieved from January 1992 to April 2006 and compared with 12 cases of MAF without recurrence and 14 cases of low-grade Müllerian adenosarcoma (MAS). EnVision immunohistochemistry of estrogen receptor (ER), progesterone receptor (PR), smooth muscle actin (SMA), CD10, Ki-67 and p53 were performed in all cases.

RESULTSAll cases of recurrent MAF of the uterus were polypoid, lobulated, and broad based mass arising from the corpus or cervix. Microscopically, the tumor consisted of benign epithelial and mesenchymal components with low mitotic activity ( ≤ 1/10 HPF). The clinical and pathologic features of 3 recurrent tumors were similar to their primary tumors, while 4 cases of recurrent tumor presented with focally higher cellularity and mitotic activity, meeting the diagnostic criteria of adenosarcoma. The stromal expression patterns of ER, PR, SMA and p53 in recurrent MAF were similar to those of clinically benign MAF and low-grade MAS. Negative or focally positive stromal cell expression of CD10 was seen infrequently in recurrent MAF (1/7) and clinically benign MAF (1/12). In contrast, a moderate to strong CD10 staining was frequently seen in MAS (9/14, P < 0.05). The difference of Ki-67-labeling index between MAF and MAS did not reach a statistical significance (P > 0.05). Ki-67-labeling index increased in areas of periglandular stromal cuffing as compared with interglandular areas in all MAS cases, but it was not observed in either recurrent MAF or clinically benign MAF cases.

CONCLUSIONSRecurrent MAF may be associated with aggressive behavior. It is difficult to distinguish MAF from low-grade MAS. CD10 and Ki-67 staining pattern in stromal cells may be helpful for the differential diagnosis.

Adenofibroma is an extremely rare benign mullerian mixed tumor composed of epithelium and mesenchymal cells. Most uterine adenofibromas occur in the endometrium, but they rarely protrude into the vagina. To date, only a few such cases with the imaging findings have been reported. Therefore, we report here on the sonographic and magnetic resonance (MR) imaging findings of a case of endometrial adenofibroma protruding into the vaginal cavity in a 28-year-old woman. The uterine adenofibroma appeared as a large intracavitary echogenic mass containing multiple small internal cysts, and it was distending the vaginal cavity on transrectal sonography. T2- weighted MR images showed a large intracavitary mass with heterogeneous high signal intensity protruding into the vaginal cavity. On gadolinium-enhanced T1-weighted MR images, heterogeneous septa-like enhancement was noted in the mass. Although uterine adenofibroma is extremely rare, adenofibroma can be suggested as a possible diagnosis when an intracavitary uterine mass, with multiple internal small cystic components and enhancing septa-like structures, is protruding into the vaginal cavity on imaging.

Toremifene is an anti-estrogen which has been shown to be effective in the treatment of breast cancer, and is thought to be a less uterotrophic agent than tamoxifen. The risk assessment concerning endometrial cancer has been inconclusive because of its rare use up to the mid-1990s. We report a case of an adenosarcoma, which is a very rare type of uterine malignancy, after toremifene treatment for 5 years in a breast cancer patient. After 1 year of toremifene use, the patient had a benign Mullerian adenofibroma. After an additional 4 years of toremifene treatment, the endometrial polypoid lesion was transformed into a Mullerian adenosarcoma. Although toremifene is a promising anti-estrogenic agent in the treatment of breast cancer patients, clinicians should not neglect the possibility of a uterine malignancy.

OBJECTIVE: To evaluate the feasibility and effectiveness of laparoscopic adnexal surgery in posthysterectomy patients and review clinical characteristics including comparison of the adhesion score of left with that of right adnexal mass. METHODS: From February 2004 to January 2007, we reviewed the medical records of 23 post-hysterectomy patients who received laparoscopic adnexal surgery including age, parity, type of hysterectomy, operative indications, histopathological diagnosis, operating time, size of the adnexal mass, adhesion score, change in the hemoglobin level, hospital stay, and any complications. RESULTS: The median age of patients was 48 years (range 35-69 years), and median parity was 2 (0-3). The median operating time was 100 minutes (range 35-180 minutes), and the median size of the adnexal mass was 7.1 cm (range 4-12 cm). The median change in hemoglobin level was 1.8 g/dL (range 0.6-4.1 g/dL). The median hospital stay was 4 days (range 3-19 days). The adhesion score was significantly higher in the left adnexal mass than in the right adnexal mass. Histopathological diagnosis included 6 cases of mucinous cystadenoma, 6 cases of functional cyst, 4 cases of hydrosalpinx, 3 cases of serous cystadenoma, 1 case of fibrothecoma, 1 case of mucinous adenofibroma, 1 case of endometrioma, and 1 case of tubo-ovarian abscess. There were no intraoperative complications or conversion to laparotomy. One case of postoperative ileus was noted. CONCLUSION: The skilled laparoscopic surgeon is capable of achieving successful result by performing laparoscopic surgery primarily to patients with adnexal mass for posthysterectomy patients who are expected to suffer severe adhesion. In posthysterectomy patients, left adnexal mass has more extensive adhesion than right adnexal mass, and these finding was represented as a high adhesion score of left adnexal mass.

Adenofibromas of the uterine cervix, which are classified as benign tumors of mixed epithelium and mesenchymal cells, are extremely rare. Most common symptom is usually abnormal genital bleeding. It is very difficult to diagnose preoperatively. Recommended method of treatment is total hysterectomy, because it usually recurs. We experienced a case of adenofibroma of the uterine cervix with increased CA125, so report it with a review of the literature.
