6.Pyelocaliceal Diverticulum.
Korean Journal of Urology 1978;19(5):441-450
Pyelocaliceal diverticulum is a well recognized uncommon entity, usually noted incidentally on excretory urography by lack of clinical symptoms, About 500 cases had been reported with similar entity till 1975. We report 6 cases of stone-containing pyelocaliceal diverticula and additional one case and the literature has been reviewed briefly.

8.Acute Leukemias with Unusual Immunophenotypes.
Korean Journal of Clinical Pathology 1997;17(1):1-9
BACKGROUND: Although immunophenotyping of leukemias has improved diagnostic accuracy and reproducibility, it has also caused diagnostic confusion regarding the lineage of leukemic cells. So far, lots of papers about acute leukemias with coexpression of another lineage markers with different technical methodologies and different criteria have been published in Korea and other countries. The authors investigated the frequency and immunophenotypic characteristics of the leukemias with aberrant lineage markers from data obtained at Korea University Hospital by a retrospective study. METHODS: From Jan. 1993 to Feb. 1996, 179 leukemias had been requested for immunophenotypig and 28 cases among them with unusual immunophenotypes were retrieved according to their immunophenotyping results. For the final diagnosis all the slides stained with Wright-Giemsa, peroxidase, Periodic-Acid Schiff, Sudan black B, and nonspecific esterase were re-examined, and all the flow cytometric results were reanalyzed. RESULTS: Among 28 cases, 3 cases(10%) were acute biphenotypic leukemias(BP) one with B lymphoid and myeloid markers and the other two with T lymphoid and myeloid markers. One case of intralineage bilinear acute leukemia(ILBL) with two separate populations of megakaryocytic cells and monocytic cells was noted. 6 cases(21%) were acute myeloblastic leukemias expressing lymphoid associated markers(Ly+AMLs; CD19) and 8 cases(28%) were myeloid antigen-positive acute lymphoblastic leukemias(My+ALLs, four with CD13+ and three with CD33+ and one with blastic transformation of chronic myelogeneous leukemia). Because of the change in diagnostic criteria, lymphocyte contamination, or low setting of negative control, 10 cases (36%) were not included to be of unusual immunophenotypes. CONCLUSIONS: Frequency of acute hybrid leukemia was 2.2 % of all leukemias. Ly+AMLs was 3.4%, and My+ALL was 4.4%. In conclusion, first, quality control of the flow cytometry and careful interpretation especially in terms of positive cut-off value and gating, are needed. Secondly, national guidelines for the criteria of the hybrid leukemia and My+ALLs and Ly+AMLs are necessary for the elucidation of the prognostic implication of those leukemias.

9.A Case of 5 alpha-reductase Deficiency in Infancy.
Journal of Korean Society of Pediatric Endocrinology 1998;3(1):96-101
5 alpha-reductase deficiency resulting in male pseudohermaphroditism is a rare disease characterized by clitoral-like phallus, bifid scrotum, urogenital sinus, testis cited in labioscrotal folds. Evaluation of plasma T/DHT ratios in infancy, particularly after hCG stimulation of the testes and elevated urinary tetrahydrocortisol (THF) to 5 alpha-tetrahydrocortisol(5 alpha-THF) ratios provide a valuable dianostic test for 5 alpha-reductase deficiency. We report one case of 5 alpha-reductase deficiency who were presented with ambiguous genitalia and elevated T/DHT ratio before and after hCG stimulation.
