Childhood pyoderma gangrenosum: A case report
並列摘要
Introduction: Pyoderma gangrenosum is a rare neutrophilic dermatosis in childhood, of unknown etiology, characterized by ulcerations. Case Report: We report a case of a boy of 5 years, hospitalized for extensive phagedenic ulcers with a characteristic centrifugal extension for 30 months. The parents had consulted several health institutions without success. The lesions were localized on the left lower limb, to the medial aspect of the right leg and the right clavicular hollow. There was ankyloses of the right knee. The hemogram showed severe anemia. Bacteriological, mycological, viral samples were negative. Histology showed a rich infiltrate of polymorphonuclear neutrophils. No other underlying pathology was identified. The child was treated with prednisone 1 mg/kg/day in digressive manner over a period of two months with a full recovery at the end of this period. He received a blood transfusion and orthopedic surgery of his right knee, followed by rehabilitation sessions. The evolution was good leaving unsightly scars from the ulcers and a recovery of walking. Conclusion: The peculiarity of this case lies in the extensiveness of the lesions, the intensity of the anemia and the diagnostic difficulties due to the large and chronic cutaneous ulcerations of the child in Africa. This results in delay of diagnosis and threatens functionality in life.
