A simple and convenient management system in coding and storage of the pathologic diagnoses was developed by generating the dBASE III with IBM-PC microcomputer. The program named "Pathology Slide Bank" can store about 3,600 data according to the SNOP coding in a standard 51/4 inch floppy disk and retrieve the data within two minutes.

BACKGROUND: Pachydermoperiostosis(PDP) is a rare genetic disease characterized by pachydermia, periostosis, arthralgia and finger clubbing. The pathogenesis of this disease is still unknown, but the concept that platelets and endothelial cells may play a major role in the developement of pachydermia is widely accepted nowadays, It is also suspected that several serum growth factors stimulate proliferation of soft tissue. OBJECTIVE: The purpose of this study was to investigate the pathogenesis of pachydermia in patients with pachydermoperiostosis through evaluating whether the fibroblasts from these patients have a higher proliferation rate than those from controls or whether the proliferation rate of those cells are affected by certain serum growth factors. METHOD: At first, we evaluated the proliferation rate of fibroblasts from patients and corntrols by the MTT colorimetric assay, and then the proliferation rate of fibroblasts from the prepuce of newborn infants under several conditions of media containing uncentrifuged patients serum, centrifuged patients serum, uncentrifuged control serum, or centrifuged control serum. RESULTS: The proliferation of fibroblasts from patients skin was slower than the control fibroblasts and fibroblasts derived from uninvolved skin of patients. The statistically significant highest proliferation rate was observed when fibroblasts were cultured in the uncentrifuged patients serum contained media and the order of proliferation was as follows: centrifuged patients serum, uncentrifuged control serum and centrifuged control serum condition at 20%, 10%, and 1% respectively. CONCLUSION: These results suggest that patients fibroblasts do not proliferate in vitro at a higher rate than control firoblasts. Fibroblasts in PDP may only play a role as target cells and certain serum factors are responsible for the pathogenesis of PDP.

A total of 53 gastric adenomas from endoscopically biopsied gastric mucosa were examined histopathologically. The average age at the time of endoscopic biopsy was 59 years, and gastric adenomas were found to be more frequent in the aged, particularly above the age of 50. The majority of adenomas occurred at the antrum. Concerning the shape of the adenomas, Yamada type II was more frequent (55%). All adenomas were accompanied by varying degree of intestinal metaplasia, and this findings suggest that gastric adenoma develops from intestinal metaplasia. In adenomas with severe atypia (grade III), endocrine cells (argyrophil and argentaffin cells) were markedly decreased or absent. Gastric adenocarcinomas coexistent with adenoma were seen in 5 (9.4%) out of 53 cases, and were more frequent in male than female patients (sex ratio, 4:1) and the average age was 61.4 years. It is suggested that there is a necessity of thorough follow-up study for definitive correlation between gastric adenoma and adenocarcinoma.

Specific cutaneous infiltrates in chronic lymphocytic leukemia(CLL) presenting as tumor and large nodule on face, scalp and upper trunk and involvement of oral mucsa is extremly rare. In 7% of cases, leukemic infiltrates of the skin precede the diagnosis of Leuke. We report herein leukemic macrocheilia which occured 3 years before a diagnosis of CLL.

Papillary carcinoma of the thyroid is a well differentiated neoplasm and usually has a good prognosis. However, a subset of morphologically distinct papillary carcinoma has bad prognoses. The tall cell variant of papillary carcinoma (TCPC), characterized by tall columnar cells with a height at least twice the width, is the one of these. In order to differentiate TCPC from usual papillary carcinoma (UPC) in terms of prognosis, we performed immunohistochemical studies for the expression of p53, bcl-2 and Leu-M1 proteins in 25 cases of TCPC, 26 cases of UPC and 14 cases of poorly differentiated, solid type papillary carcinoma (SPC) with an analysis of clinical parameters. The nuclear expression of p53 was noted in one case each of UPC and TCPC. The cytoplasmic p53 expression of TCPC, UPC, and SPC was observed in 17/25 cases (68%), 14/26 cases (54%), 3/14 cases (21%), respectively. bcl-2 expression was 19/25 cases (76%), 18/26 cases (69%), 5/14 cases (36%), and that of Leu-M1 was 21/25 cases (84%), 18/26 cases (69%), 4/14 cases(29%), respectively. There were no statistical significance in the expression of those immunoproteins among these three groups (p>0.05). The p53 protein was consistently expressed in the cytoplasm rather than nucleus in this study and was very well correlated to bcl-2 positivity (p<0.01). There were no statistical significance in any clinical parameters examined among these three groups (p>0.05). In conclusion, TCPC can not be separated from UPC as a distinct entity in this study and the cytoplasmic expression of p53 protein provides another mechanism of p53 inactivation in tumorigenesis of the thyroid papillary carcinoma, possibly by bcl-2 related mechanism.
