BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

BACKGROUND: The risk of squamous cell carcinoma (SCC) is significantly increased in chronic cutaneous ulcers. Moreover, if the proliferating epithelium of the ulcer margin shows pseudoepitheliomatous hyperplasia, it can be very difficult to discriminate between the two diseases. Enzymes such as matrix metalloproteinases (MMPs) are thought to be implicated at all stages of tumorigenesis. OBJECTIVE: We investigated the expression patterns of epithelial MMP-7 and MMP-13 in chronic ulcers and SCCs by an immunohistochemical technique and the usefulness in differentiating these two entities. METHODS: Formalin-fixed and paraffin-embedded tissues obtained from 16 chronic ulcers and 12 SCC patients were studied using an immunohistochemical staining method for MMP-7 and MMP-13. RESULTS: MMP-7 and MMP-13 were expressed by the malignant tumor cells of 4 (33.3%) and 9 SCC samples (75%), respectively, while they were absent from the proliferating epithelium of chronic ulcers. CONCLUSION: Our results suggest that epithelial expression of both MMP-7 and MMP-13 have a specificity in differentiating the benign epithelial proliferation of chronic ulcer from malignant tumor cells, but MMP-13 seems to be a more sensitive and useful marker due to the lower sensitivity of MMP-7 in SCCs.

Lymphomatoid papulosis is a strange disease; clinically benign, histologically malignant. Clinically, it may simulate pityriasis lichenoides et varioliformis acuta. The diagnosis is based on the typical histopathological features suggestive of malignant lymphoma, due to the presence of polymorphous lymphoid infiltrate consisting of small lymphocytes intermingled with conspicuous large atypical cells. We experienced a case of lymphomastoid papulosis in 35-year-old woman. Initially, her skin lesions developed as erythematous papules on the extremities, gradually spreading centrifugally with a tendency to involute slowly without treatment, leaving brown wrinkled surface and shallow ulceration. These skin lesions tended to become worse in warm weather and better in cold weather. At first visit, multiple erythematous grouped, ulcerated papules and nodules are seen. 18 months after first visit, most skin lesions are regressed except 5 erythematous pinhead sized papules on right leg in spite of no treatrnent. Labcratory examiniations of CBC, VDRL, urinatlysis, blood chemistry and chest X-ray were all within normal limits. Histopathologically there were hygerkeratosis, mild acanthosis, exocytosis in epidermis, and numerous lymphoid cells were infiltrated especially on perivascular and periappendegeal area, and many atypical cells showing hyperchromatic nuclei, kidney-shaped nuclei and mitotic figures in dermis.
