Abstract
IntroductionPyoderma gangrenosum is a rare, idiopathic, inflammatory, neutrophilic dermatitis characterized by sterile skin ulceration. It can be associated with an underlying pathology, especially inflammatory bowel disease and hematological malignancies. Its association with a malignant pathology in the context of a paraneoplastic syndrome is more commonly described in hematological malignancies, with solid tumors being rare.Case reportWe report a case of a 39-year-old West African man with pyoderma gangrenosum that developed 6 months before the clinical expression of rectosigmoid junction cancer. The removal of the cancer resulted in the patient’s recovery.ConclusionRecurrent pyoderma gangrenosum lesions may be the expression of colonic adenocarcinoma in paraneoplastic syndrome and require colonoscopy, especially in at-risk patients.

Summary
Pyoderma gangrenosum (PG) is a rare, idiopathic, inflammatory, neutrophilic dermatosis that is generally characterized by recurrent sterile skin ulceration, with rare extracutaneous involvement [1,2,3]. This case is peculiar because of the occurrence of PG lesions 6 months before the onset of rectosigmoid junction cancer symptoms and their disappearance after tumor removal This shows that PG may be the first manifestation of colorectal adenocarcinoma in paraneoplastic syndrome. The patient had recurrent skin lesions of different ages on the lower limbs that had started to appear 6 months before the onset of abdominal pain. These lesions began with an inflammatory nodule that resolved within a few days with a pustule that ruptured quickly and spontaneously gave way to an ulceration whose diameter quickly reached several centimeters. Thirteen months after the operation, all the skin lesions had healed without reemergence of new lesions, and the patient did not have metastases or tumor recurrence
