Аннотация
INTRODUCTION: Pyoderma gangrenosum (PG) is a rare sterile neutrophilic dermatosis characterized by painful recurrent ulcerations. It is frequently associated with inflammatory bowel disease, rheumatoid arthritis, or malignancies. PG is a diagnosis of exclusion, and it is based on clinical presentation, histology, history of an underlying disease, and exclusion of other causes of ulceration.
CASE REPORT: The authors report a 62-year-old male who developed a nonhealing ulcer at the site of incision following nephrectomy for renal cell carcinoma. Past medical history included chronic lymphocytic leukemia treated with rituximab. Histology of the skin lesion showed a phlegmonous nonspecific inflammation without being able to differentiate between a necrotizing wound infection and PG. The patient's condition was initially diagnosed as an infectious process and treated accordingly. After unsuccessful results with systemic antibiotics, high-dose corticosteroids induced prompt healing of the wound. On these bases, the diagnosis of postoperative PG within chronic lymphocytic leukemia and renal cell carcinoma was made.
CONCLUSION: Faced with postoperative necrotizing ulceration resistant to correctly administered antibiotics, PG must be considered. In such condition, the diagnosis must not be guided primarily by histology and early advice of a dermatologist is recommended.
