The accessory ovary can be defined as an extraovarian tissue that is located near the normal ovaries and is connected to the broad ligament, infundibulopelvic ligament or utero-ovarian ligament. It has very rarely been reported. The majority was found during abdominopelvic surgeries for any other purposes, because they were usually small and less than 1 cm in diameter adn gave no particular symptoms related simply to their presence. We reported a case of accessory ovary in which developed a simple cyst of a largest diameter of 12 cm, and discussed the significance of the accessory ovary in clinical and pathological aspects.

The purpose of this study is to evaluate the prognostic significance of argyrophilic nucleoalr organizer regions (AgNORs) and proliferating cell nuclear antigen (PCNA) by using DMBA hamster buccal pouch carcinogenesis which provides a good experimental model in reproducing steps from precancerous lesions to invasive squamous cell carcinomas. The buccal pouches of 50 Syrian hamsters were applied with 0.5% DMBA in mineral oil three times a week to reproduce various lesions from precancerous ones such as hyperkeratosis or epithelial dysplasia to invasive squamous cell carcinomas. Their sections were stained with H & E, and silver colloid, and processed immunohistochemically by being applied with monoclonal antibody to PCNA. The histopathologic examainations were done and the counts of AgNORs were evaluated. The PCNA labelling indices on each lesions were evaluated. The correlation between histopathological grades and counts of AgNORs or PCNA labelling indices were evaluated. The number of AgNORs was 2.22+/-0.22 in control group, 3.46+/-0.72 in carcinoma in situ (CIS), 3.78+/-0.63 in squamous cell carcinoma (SCC), respectively. AgNORs significantly increased in severe epithelial dysplasia, CIS, and SCC compared with normal tissue (P<0.05). The PCNA Labeling Index (LI) was 39.47+/-6.68% in control group, 79.61+/-4.14% in CIS, and 85.43+/-6.25% in SCC, respectively. PCNA LI also significantly increased in epithelial dysplasia, CIS, and SCC compared with normal tissue (P<0.05). The number of AgNORs, AgNOR area, and PCNA LI slightly increased in the advancing front than in the center of SCC, but, it was not statistically significant. It appeared that there were a good correlation between the number of AgNORs and PCNA LI (Pierson correlation coefficient : 0.649, P<0.001). These results suggested that the number of AgNORs and the PCNA LI could be useful markers for evaluating the risk of malignant transformation and prognosis of SCC. It was thought that the clinical usefulness of these markers should be verified by using human tissue specimens.

STUDY DESIGN: A retrospective analysis of the patients who had cauda equina syndrome caused by a herniated lumbar disc. OBJECTIVES: To assess the clinical debates concerning the diagnosis, treatment, and results of treatment. SUMMARY OF LITERATURE REVIEW: This syndrome has been considered as an absolute indication of surgical treatment in the herniated lumbar disc and poor prognosis after surgery were reported. Although there are debates on the timing of surgery, early recognition early surgical treatment are recommended for a better results of treatment. MATERIALS AND METHODS: 23 consecutive patients having a cauda equina syndrome caused by herniated lumbar disc were reviewed retrospectively. They were 14 males and 9 females having ages of 41.6 in average. The incidence of this syndrome was 3.8% of the patients who had surgical treatment of herniated lumbar disc. RESULTS: All patients had bladder dysfunction in addition to the low back pain and radicular pain in the leg, but five patient did not recognize their urinary retention which were shaded by severe leg pain. A surgical treatment were performed for all patients at 6.8 days in average after onset of the bladder dysfunction. At follow-up of 3 years and 3 months in average after surgery, 20 patients(86.9%) had satisfactory resolution of the low back pain and leg pain, and all patients had complete recovery of motor weakness except one patients who had residual foot drop. Bladder function recovered satisfactorily in 18 patients (78.3%), but 4 patients had some difficulty of urination and one patient needed a sphinterotomy for urination. CONCLUSIONS: The cauda equine syndrome in herniated lumbar disc was often not recognized early and a poor result of treatment was not rare, particularly in the patients who had acute onset and severe bladder dysfunction. So, early diagnosis and active surgical treatment are recommended for a better results of treatment.

We report our experience of renal polyomavirus infection after renal allograft leading to graft dysfunction. A fourty seven-years-old male patient, has been on Tacrolimus based dual immunosuppression, showed graft dysfunction with rising serum creatinine at post-transplant day 140. His graft function had been good without any acute rejection episode. A tentative diagnosis of acute rejection was rendered and core needle biopsy was performed. Viral infection was initially suggested by the occurrence of markedly enlarged tubular epithelial cells containing large nuclei with smudgy chromatin pattern. Confirmatory diagnosis of human polyomavirus induced interstitial nephritis was obtained by electron microscopy, which showed viral particles in the nuclei of tubular epithelial cells. After Tacrolimus was converted to cyclosporine, renal function was stabilized. A review of the literature indicates that asymptomatic infection, ureteric stricture, and hemorrhagic cystitis are other possible manifestations of polyomavirus in the human urogenital tract. According to some prior reports, polyomavirus induced interstitial nephritis might be a cause of graft loss. But our patient has retained a stable graft function with a chnange of immunosuppression.
