Clinical analysis of 170 patients with childhood leukemia was made, who were admitted to the department of Pediatrics, Pusan Paik Hospital, Inje University, College of Medicine during 10 years from 1981 to 1990. The results were as follows: 1) The annual number of the patients with childhood leukemia was in the range of 6~25 cases. And the annual rate of the number of the patients in the department of the Pediatrics was 0.37~1.60% with the average of 1.06%. 2) Of the 170 patients, 72 cases(42.3%) were in the range of 0~5 years of age, which was the largest age group. In male, of the 97 patients, the largest age group was the age group of 0~5 years, which included 45 cases (46.4%), while in female, the largest was that of 6~10 years, which included 29 cases of 73 patients (39.8%). 3) Of the 170 patients, sex ratio was 1.33:1 with male dominance in all age groups except 1:1.6 with female dominance in the age group of 6~10 years. 4) Of the 170 patients, 113 cases were ALL (66.5%), 50 cases AML (29.4%), and 7 cases CML (4.1%). 5) In ALL, 51 cases of the 113 patients (45.1%), were in the age group of 0~5 years, 35 cases (31%) in the age group of 6~10 years, and 27 cases (23.9%) in the age group of 11~15 years. In AML, 19 cases of the 50 patients (38.0%) were in the age group of 0~5 years, 17 cases (34%) in the age group of 6~10 years, and 14 cases (28%) in the age group of 11~15 years. 6) In ALL, the sex ratio of male: female was 1.21:1, 1,50:1 in AML, and 2.5:1 in CML. 7) According to the FAB classification in ALL, of the 113 patients, 72 cases (63,7%) were in L1 type, 34 cases (30.0%) in L2 type, and only 3 cases in L3 type.

The multiple lentigines syndrome or LEOPARD syndrome is an autosomal dominantly inherited disorder with a variety of abnormalities and a familial occurrence. This syndrome is characterized by the presence of numerous dark brown macules on the skin but not the mucous surface, and by a marked increase in the number of lentigines from birth to puberty. The eponym LEOPARD stands for lentigines, EKG abnormalities, ocular hypertelorism, pulmonary stenosis, abnormalities of the genitalia, retardation of growth and deafness. We report a case of multiple lentigines syndrome in 7-year-old boy. He had numerous pinhead to pea sized, dark brownish macules scattered on the entire body and also had pulmonary stenosis, EKG abnormality, ocular hypertelorism and right exotropia. Interestingly, he also had a labial melanotic macule on the lower lip, which is usually spared in the multiple lentigines syndrome. Histologically, the biopsy specimen taken from the macule revealed an elongation of rete ridges, an increase of melanin pigments in the basal layer and mild inflammatory infiltrates intermingled with the melanophages in the upper dermis.

The firat caae of hemangioma originating in the skeletal muscle was reported by Linton in 1843. Hemangiama involving the skeletal muscle ia less common and the correct preoperative diagnosis is often not made even tbough they attain considerable size. These tumors have remained asymptamatic and undetected by their hosta. We experienced 5 cases of hemangiama in the skeletal muscle for 2 years since 1979 and the diagnosis were confirmed clinicopathologically.

PURPOSE: Dysembryoplastic neuroepithelial tumor (DNET) is a newly described, pathologically benign tumor arising within the supratentorial cortex. We reviewed the MR appearance of five patients with DNET, emphasizing the clinical and radiologic features. MATERIALS AND METHODS: MR images in the five patients (three male and two female) with a history of epileptic seizure and pathologically-proven DNET were retrospectively reviewed. We analyzed the location, configuration, signal intensity, contrast enhancement, vasogenic edema and calcifications of these tomors. RESULTS: The tumors were located mainly in the cortical to subcortical area with very little perifocal mass effect on MR imaging. They were essentially hypointense on T1-weighted imaging, and showed a hyperintense well circumscribed mass on T2-weighted imaging and a thick gyrus-like configuration was retained within the lesions. On contrast enhanced study, focal nodular enhancement was seen in one patient, and multifocal nodular enhancement in two. CONCLUSION: DNET is rare benign tumor resulting in often medically intractable epileptic seizure and shows a characteristic gyriform configuration, well-described lobular tumor margins and sometimes multifocal nodular enhancement. These radiologic features may aid in differentiating DNET from ganglioglioma and other gliomas.

To examine AZT resistance of HIV-1 isolates from AZT treated or untreated Korean, several biological characteristics such as syncytium formation, HIV-1 reverse transcriptase activity and the p24 antigen production in MT-2 cells infected with 4 HRT_1 isolates were determined. As controls, we tested HIV-1 HTLV-IIIB and pre-drug isolate as AZT susceptible strains, in addition to HIV-1 RTMC/MT-2 and post-drug isolate as AZT resistant strains. When the inoculum size of HIV-1 was 300 TCID50well and 100 TCID50/well, the AZT susceptibility of AZT untreated HIV-1 isolates 8806 and 9571 were similar to that of HIV-1 HTLV-IIIB and AZT-susceptible HIV-1 strains. When we evaluated AZT resistance of isolates HRs-1 8812 and 9113 treated with AZT for 36 months by observation of syncytium formation, HIV-1 8812 showed resistance simillar to that of HIV-1 RTMC/MT-2 strain forming syncytium up to AZT 1microgram/ml, and HIV-1 9113 showed resistance identical with that of AZT-resistant HIV-1 strain which formed syncytium up to AZT 10 microgram/ml. Especially, when we evaluated AZT resistance by HIV-1 reverse transcriptase activty and the p24 antigen production, HIV-1 isolates 8812 and 9113 showed much higher resistance (>10 - 200 fold) compared with HN-1 RTMC/MT-2 and AZT-resistant HIV-1 strain.
