We describe a case of polyposis coli, which was followed by development of desmoid in the rectus adbominis muscle and fibromas in the mesentery during an interval of two years. This case supports the hypothesis that, in Garder's syndrome, the traumatic injury by colectomy triggers an unusual fibrous proliferation in the peritoneal cavity and incision site under the possible genetic basis.

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.

Two cases of malignant histiocytosis, in which skin involvement was a prominent finding at initial clinical presentation, are reported. 1nteresting histopathologic findings, including Langerhans granule in one case and numerous eosinophils in another, were observed. In one case remission was achieved with BACOP chemotherapy (Bleomycin, Adriamycin, Cyclophosphamide, Vincristine, and Prednisone). In the other case, the patient died nine months after the onset of the disease without any treatment.

BACKGROUND: The prevalence of pulmonary tuberculosis among the elderly is increasing in Korea and in the developed countries due to the increased elderly population and their predispositions to chronic disease, poverty and decreased immunity. To define the characteristics of pulmonary tuberculosis in the elderly, we evaluated the clinical spectrum of pulmonary tuberculosis. METHODS: We analyzed 92 patients retrospectively that were diagnosed as active pulmonary tuberculosis over the age of 65. The analysis involved patient's profiles, clinical manifestations, coexisting diseases, diagnostic methods, anti-TB medications and their side effects, and treatment outcomes. RESULTS: The results were as follows:- 1) The ratio of male to female was 2.1:1(62:30 cases) 2) Chief complaints were a cough (47.8%),dyspnea(40.2%), sputum(38.0%), chest pain(12.0%), anorexia(10.9%), and fever(9.8%). 3) 38(41.3%) of cases had a past history of pulmonary tuberculosis. 4) The coexisting diseases were:-COPD, 25 cases(27.2%);pneumonia, 17 cases(18.5%);DM, 13 cases(14.1%);and malignancy, 10 cases(10.9%). 5) The positivity of Mantoux test(5 TU, PPD-S) was 82.7%. 6) Pulmonary tuberculosis was diagnosed using the following methods : sputum AFB (Acid Fast Bacillus) smear 42.4%, sputum TB(M.Tuberculosis) culture 15.2%, sputum TB PCR (Polymerase Chain Reaction) 10.9%, bronchial washing AFB smear 2.1%, chest radiology only 25.0%. 7) Locations of radiologic lesions were RULF, 50 cases;RLLF, 50 cases, mostly, then LLLF;26 cases were leastly involved. 8) The coexisting tuberculosis were endobronchial TB(8.7%), TB pleurisy(7.6%) miliary TB(5.4%), intestinal TB(2.2%), renal TB(1.1%) 9) The proportion of treatment regimen with 1st line drug and 2nd line drug were 92.3% and 7.6%, respectively. 10) The outcome of treatment were as follows:cured 31.5%, expired 13.0%, no return 47.8%, follow-up now 7.6%. CONCLUSION: The pulmonary tuberculosis in the elderly has atypical patterns with chronic coexisting diseases. Therefore, the possibility of pulmonary tuberculosis should be considered in elderly patients with pulmonary symptoms.
