OBJECT: Pre-ALL is a very rare preteukemic state, which percedes acute lymphocytic leukemia, while MDS(pre-ANLL), usually the well-known type of preleukemic state, precedes acute non-lymphocytic leukemia. Initially it shows transient pancytopenia without any evidence of leukemia in bone marrow findings, followed by acute lymphocytic leukemia after recovery from pancytopenia of a short period within weeks or months. We report a case with pre-ALL in childhood. CASE: A 15-month-old male baby was admitted with the complaints of fever and cough for 5 days and pallor for 2 weeks prior to admission. On admission, CBC showed pancytopenia without any evidence of leukemia, which was recovered spontaneously in a short period, and then was followed by acute lymphocytic leukemia of CALLA negative, early pre-B cell type. During antileukemic chemotherapy, he had suffered from severe bacterial infections and was finally died of sepsis 8 months after first admission. CONCLUSION: We report a case of pre-ALL in childhood, which was preceded by CALLA negative, early pre-B cell ALL, with a review of the literatures, briefly.

Multidrug resistance(MDR) phenotype is frequently observed in animal and human cancer cell lines selected for in vitro resistance to a single chemotherapeutic agent. It is characterized by the diminished j drug accumulation and is related to the drug efflux mechanism in resistant cells. In the present study, adriamycin resistant cells(L1210-AdR6 : 10-6M adriamycin, -AdR5: 10-5M) and vincristine resistant cells (L1210-VcR7: 10-7M vincristine, -VcR6: 10-6M) were produced from mouse lymphoblastic leukemia cell line L1210. Growth profiles of survived cells were observed for 5 days with MTT(thiazolyl blue) assay and resistance was compared with IWdrug concentration of 50% survival reduction in absorbance). Resisrant cells proliferated more slowly than sensitive cell. Doubling times were 29.7hr in L1210, 68.7hr in L1210-AdR5 and 58.2hr in -VcR6. MDRs expressed as resistance factor were as follows, L1210-AdR5 was 76.4 times for vincristine, L1210-VcR6 was 96.4 times for adriamycin. The cell membrane proteins with three different M.W. were recognized to be related resistance, 220, 158, and 88 kd in L1210-AdR5, 158, 140 and 88 kd in L1210-VcR6 by SDS-PAG electrophoresis. Cell surface membrane proteins were identified by radio-iodination and autoradiogram. their molecular! weights were 158, 72.8. and 42.4 Kd in L1210-VcR6.

Before surgery for hemorrhoid, patients always have a worry of postoperative recurrence. The exact incidence and risk factors of recurrent hemorrhoid have not yet been delineated up to now. Therefore, the aim of this study was to assess the etiology of the recurrence after surgery. MATERIAL AND METHODS: Between March, 1997 and Feburary 1998, all patients who visited the Dept. of Surgery, Korea Veteran Hosipital, due to the recurrent hemorroid after surgical managememt including sclerotherapy(Group II: GII, n=60) were compared to the age and sex mathed(1:2) with primary hemorroid patients(group I: GI, n=120). The risk factors which might be related with the recurrence such as 1) hemorroidal factor(duration of symtom, symtom, associated perinial disease) 2) patient factor (constipation, incontience, cardiovascular disease, pulmonary and hepatic disease) 3) anorectal physiologic factors 4) surgical factors were evaluated. Stastical analysis were performed by a chi-square-test or Mann-Whitney U test and set the significance at p<0.05. RESULTS: There were no differences between the two groups in terms of age(GI 58.1+/-8.5, GII 60.9+/-3.3 years), gender(M:F, GI; 97:23, GII; 56:4 ). The ratio of having a contipation before surgery was 41% in GI, 55% in GII. It was not statistically significant. However, the other factors related with constipation such as duration of constipation(GI; 9.85+/-7.73 years, GII; 14.62+/-7.38 years: p<0.05), duration of straining during defecation(GI; 5.82+/-2.34, GII; 7.32+/-5.6 minutes, p<0.05) number of laxative use(GI; 29, GII; 28) were significantly different between the two groups. The fecal incontince are 5% in group Iand 13% in group II. There were no differences in patient's subject symtoms related with hemorrhoid, and comorbid perianal disease between the two groups. In anorectal manometric findings, rectal complince was significantly lower in GII than that of GI(25.1+/-50.04 cc/cmH20 vs 16.0+/-25.2 cc/cmH20 p<0.05). GII has a significant number of preopertive hypertension than GI(6.7% vs. 21.6%, p<0.05). CONCLUSION: When a patient with hemorrhoid has a constipation or hypertension, and lower compliance in manometric findings, it would be related with the postoperative recurrence after treatment. Therefore, we surgeons should correct these comorbid conditions before surgery, otherwise give an information to the patient of high chance of postoperative recurrence after management.

Hyalinizing trabecular adenoma is an uncommon benign thyroid tumor that is recently described in the literature. This tumor is easily confused with medullary carcinoma on surgical specimens and with papillay carcinoma on cytologic specimens. Herein we report the cytologic characteristics of a case of histologically proven hyalinizing trabecular adenoma of the thyroid gland. Cytologically, the aspirate showed trabecular or individually dispersed polygonal cells with finely stippled chromatin pattern, nuclear grooves, and eosinophilic nuclear pseudoinclusions. No colloid materials were noted in the background.

The cytologic findings in fine needle aspiration of a case of myxoid liposarcoma of the mediastinum are described. The smear and cell block of the aspirate revealed solid clusters with background of amorphous material and scattered single tumor cells. The clusters were moderately cellular and consisted of atypical lipoblasts in varying stages of differentiation and delicate plexiform capillaries. Good correlation was found between the histologic and cytologic findings in the fine needle aspirates. The differential diagnosis between myxoid liposarcoma and other myxoid soft tissue tumors is discussed,
