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.

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.

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.

We report herein a case of lymphomatoid papulosis in a 23-year-old female who had recurrent erythematous pinhead to pea sized papules and nodules on the both inner thighs and forearms for 4 years. Some lesions showed central hemorrhagic necrosis or scale formation. Individual lesions persisted for several months and showed spontaneous regression leaving pigmentation or depigmented atrophic scar. Histopathologically, there was marked cell infiltration, especially in the dermoepiderrnal junction and perivascular area. Infiltraled cells consisted of sorne ncutrophils and numerous atypical cells that had variable sized and irregular shaped nuclei. Electronmicroscopically, some atypical cells had cerebriform nuclei with marked peripheral condensation of chromatin and cytoplasm contained a few organelles, many polyribosomes and some dense bodies.

BACKGROUND: Several studies about myelodysplastic syndromes (MDS) have demonstrated that patients with high score of erythrocytic and total dysplasia showed a significantly lower degree of acute myeloid leukemia (AML) development. We analyzed correlation between bone marrow dysplasia and peripheral blood indices, and estimated the value of peripheral blood indices substituted for bone marrow examination to predict the progress of MDS to AML. METHODS: RBC count, MCV, RDW, WBC count, platelet count, MPV, and PDW were measured by Coulter Counter STKS (USA). We calculated the granulation score (G-score), percentage of peudo-pelger polymorphs (PPP) in the peripheral blood film, and examined the dysplasia in bone marrow aspirates. The reticulocyte survival study was performed with the venous blood collected in CPDA-1 under sterile conditions which was incubated immediately after collection at 37degrees C. RESULTS: G-score was inversly correlated with granulocytic and total dysplasia, but highly scored PPP showed a significantly lower degree granulocytic and total dysplasia. Reticulocyte survival curves showed variable pattern according to degree of erythrocytic and total dysplasia. Patients with a high degree of erythrocytic and total dysplasia showed significant difference compared with normal control group. MPV was increased in accordance with increase in megakaryocytic and total dysplasia. A lower score for erythrocytic and total dysplasia was observed in RAEB-t than in RA and RAEB. CONCLUSIONS: It is suggested that G-score, PPP, and MPV in peripheral blood as well as reticulocyte survival curve may be good markers for bone marrow dysplasia, and erythrocytic and total dysplasia in RAEB-t is lower than in RA and RAEB. Therefore, peripheral blood indices can be used to predict the progress of MDS to AML
