Immature teratoma accounts for less than I percent of all ovarian teratomas and occurs commonly in young individuals, the peak incidence being in the second decade. It contains a variable mixture of mature and immature tissues in which neuroectodermal elements almost always predominate. Gliomatosis peritonei, miliary implants of mature glial tissues on the peritoneum or omentum, is an infrequently reported complication of mature or immature ovarian teratomas. We describe the first case in Korea of a 12-year-old girl with an immature teratoma and numerous glial peritoneal implants.

This report describes a case of ileal obstruction in a 31-year-old male with acute abdominal pain. A plain film of the abdomen showed segmental obstruction of small intestine. The patient underwent laparoscopic resection of the segment. Microscopic examination demonstrated foci of ulceration, submucosal edema, transmural inflammation, mural and neural hyperplasia and noncaseating granulomas, mimicking Crohn's disease. However, there were microabscesses predominantly composed of eosinophils. Furthermore, a section of an adult heterophyid trematode was identified in the crypt. Heterophydiasis usually causes diffuse enteritis. Therefore, this case with intestinal obstruction seems to be a rare manifestation of intestinal heterophydiasis.

In order to evaluate the effect on nimodipine on the cerebral vasospasm, twelve adult mongrel dogs were studied in this experiment. This animals were divided into 2 groups ; Intracisternal injection of autogenous blood(Group I : no treatment group) and intravenous nimodipine administration after intracisternal injection of autogenous blood(Group II : treatment group). Nimodipine was administered 12 hours after intracisternal injection of autogenous blood for 7 days. Dogs were sacrificed at 8th day after intracisternal injection of autogenous blood and the unltrastructual changes were studied. The results were as follows : In Group I basilar artery showed endothelial cell swelling with distruption of intercellular junction, subendothelial edema and thickening of the internal elastic lamina with marked edematous change. The pathologic changes of arteries in Group II were considered more favorable than that of Group I. These results suggest that early intravenous treatment with nimodipine is beneficial in the treatment of vasospasm of this models.

Leiomyomas are benign tumors of smooth muscle origin and are very rare in the female genital tract. To date, approximately 35 cases of urethral leiomyoma have been reported in the literature. A 34-year-old woman presented with a 3-year history of a mass at the urethral meatus. Physical examination showed 2 x 1.5 cm lump at the urethral meatus, posterior lip. Histologically the tumor was mainly composed of benign cigar shaped smooth muscle izells which were arranged in interlacing fascicles without cellular atypia or mitosis. Immunohistochemistry confirmed leiomyoma with positive staining for vimentin, desmin and muscle specific actin.

A 2-month-old female infant presented with a bluish-black, flat, hairy patch, 1.2cm in diameter, on the posterior aspect of her neck since birth. Histologic sections from the lesion showed numerous diffusely scattered dermal melanocytes throughout the dermis. The histopathologic and clinical findings were not fully oonsistent with any other known dermal melanocytosis. The diagnosis of “hairy blue nevus” was proposed for this unique lesion.

In general, soft tissue and bone tumors are diagnosed clinically by physical findings, laboratory data, and X-ray findings with only limited reliability, and a definite diagnosis must be supported by histopathological evidence. For this purpose, open biopsy routinely has been carried out, but there have been many disadvantages and sometimes followed by surgical complications. The present study was undertaken to compare the cytologic findings of soft tissue and bone lesions with the histological findings. The specimen were obtained by fine needle aspiration and Franklin-Silverman needle. For cytodiagnosis Stormby's cell block of aspirates were utilized. For histological diagnosis small tissue fragments obtained by the Franklin-Silvermans cutting needle were used. Then, the diagnostic accuracy of 3 different methods were compared, and the clinical applicability of those methods as adjunctive diagnostic procedures in the diagnosis of the soft tissue and bone tumors were assessed. The results obtained were as follows: l. In 15 out of the 20 cases (75%) in which clinically and roentgenologically the soft tissue and bone tumors were suspected, sufficient material was aspirated to enable detailed cytological diagnosis possible by fine needle aspiration. ln 13 out of the 15 cases, diagnosis could be made by cytologic findings, which was similar to histologic findings of tissue obtained by Franklin-Silverman needle. 2. In 6 out of the 20 cases, sufficient tissue fluid for cell block preparation were obtained from the tumor tissues. In 5 cases, cytologic findings of cell blocks were consistent with that ot the tissue obtained by Silverman needle. But in one case malignancy was susupected by cytodiagnostic method, and definite diagnosis could not be made. Finally the lesion was found to be malignant schwannoma through the histological study of tissue specimen obtained by Franklin-Silverman needle biopsy. 3. In 19 out of the 20 cases, diagnosis could be made by Franklin-Silverman needle biopsy. 4. Diagnostic accuracy of the lesions by clinical and roentgenological method was 75%, which overall diagnostic accuracy of 3 methods were 86.7% in aspiration cytology, 83.3% in cytodiagosis of cell block and 95% of histodiagnosis of tissue specimen obtained by Franklin-Silverman needle. Through this study it is found that cytodiagnostic method of aspirates and histodiagnosis of the small tissue specimen by Franklin-Silverman needle are very useful adjunctive methods in enhancing the diagnostic accuracy of the soft tissue and bone lesion prior to open biopsy trial.

Island flaps have been widely used for the management of soft tissue defects in reconstructive surgery. The necrosis of the flap has been a catastrophe in clinical fields. It is well known that revascularization to the flap after ligation of its pedicle comes from the recipient bed and flap margins. The authors investigated the effects of the ischemic recipient bed on island flap survival after the ligation of its pedicle in the rats. One hundred and thirty inferior epigastric island flaps were divided into three groups (Group I, Group II, and Group III) according to the degree (0%,20%, and 60%) of interruption of contact of flap with the recipient bed, respectively. In Group I,the vascular pedicles were ligated before and on the 0, 2nd, 3rd, 4th and 5th days after flap elevation, and in Group II & III, the vascular pedicles were ligated on the 2nd, 3rd, 4th and 5th days after flap elevation. Flap survival was assessed on the 3rd day after pedicle ligation. Microangiographic studies were also performed on the 3rd day after pedicle ligation to study revascularization within the flap and the change of blood vessels around the flap margins. The results were as follows: 1. Flap survival was increased significantly in the flaps with pedicle ligation on the 4th and 5th postoperative days compared to those at the 2nd and 3rd postoperative days. 2. From the 3rd postoperative day, flap survival was not influenced significantly by the degree of limited bed contact and the date of pedicle ligation. 3. In spite of limited bed contact, the flap will likely survive with abundant revascularization from the flap margins. In conclusion, the flaps with limited bed contact were revascularized significantly from the flap margin by the 3rd postoperative day.
