Pyoderma gangrenosum on the finger.
A case of pyoderma gangrenosum on the dorsal aspect of the right second and third fingers of a 50-year-old woman is reported. The patient had been wounded at the above-mentioned site by a cutter. This wound developed into a painful ulcer which enlarged rapidly. No bacterial infections were detected. Histologically, an inflammatory infiltrate of lymphocytes mixed with neutrophils and nucleodusts was seen throughout the entire dermis, but there was no evidence of vasculitis. Based on this data, the case was diagnosed as pyoderma gangrenosum. The patient responded to treatment with systemic corticosteroids. Pyoderma gangrenosum at this site of the fingers seems to be rare.
