INTRODUCTION: Fibrous-osseous lesions of the jaws are difficult to diagnose precisely until excised biopsy results are found, so they might be confused with malignant lesions. This clinical study focused on the diagnostic aids of lesions that demonstrate different clinical, radiologic, and histological findings. MATERIALS AND METHODS: A total of 16 patients with benign fibrous-osseous lesions on the jaws (6 fibrous dysplasias, 6 ossifying fibromas, 3 cemental dysplasias, and one osteoblastoma) were reviewed. Nine patients with malignant fibrous-osseous lesions (8 osteosarcomas and one Ewing's sarcoma) were also retrospectively reviewed. RESULTS: Osteosarcoma patients complained of facial swelling and tooth mobility. The radiographic findings showed the irregular resorption of cortical bone and periosteal reactions. Histological features included cellular pleomorphism and atypical mitosis. An Ewing's sarcoma patient complained of tooth mobility and facial swelling. Onion-skin appearance and irregular expansile marginal bony radiolucency were seen in the radiography. Fibrous dysplasia patients complained of facial swelling and asymmetry. The radiographic features were mostly ground-glass radiopacity. Histological findings showed a bony trabeculae pattern surrounded by fibrous ground substances. Ossifying fibroma patients complained of buccal swelling and jaw pains, showing expanded cortical radiolucent lesions with a radiopaque margin. Histological findings were revealed as cellular fibrous stroma with immature woven bones. In cemental dysplasia, most of their lesions were found in a routine dental exam. Well-circumscribed radiopaque lesions were observed in the radiography, and cementum-like ossicles with fibrous stroma were seen in the microscopy. An osteoblastoma patient complained of jaw pain and facial swelling. Radiographic findings were mottled, dense radiopacity with osteolytic margin. Trabeculae of the osteoid with a vascular network and numerous osteoblasts with woven bone were predominantly found in the microscopy. CONCLUSION: Our study showed similar results as other studies. We suggest the clinical parameters of diagnosis and treatment for malignant and benign fibrous-osseous lesions of the jaws.

The aim of this study was to identify the usefulness of pelviscopy in treatment besides its diagnostic value. The advantages of pelviscopic surgery are low cost, rapid recovery, good cosmetic effect, low incidence of complication and postoperative adhesion. So most of the pelvic exploration in gynecologic patients are replaced by the pelviscopic surgery these days. Pelviscopic surgery was performed on 136 patients at the Department of Obstetrics and Gynecology, College of Medicine, Yenungnam University from May 1991 to July 1993. The results obtained were as follows : The age distribution of the patients was from 19 to 55 with age of 31.2 years, and the mean parity was 0.96, the most common indication of pelviscopic surgery was tubal pregnancy(66.9%), the second most common indications was ovarian cyst(10.3%) and the other indications were endometriosis, corpus iuteum cyst rupture, parovarian cyst, foreign body, tubal ligation, hydrosalpinx, uterine myoma and in 16.3%. The mean duration of hospitalization was 2.1 days without specific complications. According to these results, it was postulated that the pelviscopic surgery was a useful operative tool in gynecologic treatment and its application could be extended to many other areas of gynecology with safety by the development of surgical techniques and instruments.

Primary ovarian pregnancy is one of the rerest types of extrauterine pregnancy. But an increase in the reported prevalence of ovarian pregnancies was published in recent years. Three cases of ovarian pregnancy which have Spiegelberg criteria are presented with a brief review of literatures.
