[Clinical analysis of 6 cases of pyoderma gangrenosum].
This article reports 6 cases of pyoderma gangrenosum of either acute or chronic clinical type. Etiologically, we found that minor local trauma could induce ulcerative and destructive lesions, with typical pyoderma gangrenosum features following in 4 cases. All the patients responded well to systemic corticosteroids. In comparison with cases reported in other countries, no systemic diseases (including ulcerative colitis, Crohn's disease and polyarthritis) were found in our series. Cultures taken from early pustular lesions were sterile. Histopathological examination showed heavy neutrophilic infiltration in the dermis, and no evidence of vasculitis was found in the biopsies. Immunological investigations revealed no specific reactions in our cases.
