Description

<p> A 53-year-old male presented to our emergency center with the chief complaint of an abscess involving the anus and extending to the scrotum. Computed tomography revealed fat stranding, edema, and inflammatory changes extending from the buttocks to the scrotum. The patient underwent emergency incisional drainage and colostomy. We performed several debridement procedures, but his anemia persisted. Thereafter, he underwent lower endoscopy to investigate the cause of his anemia. We found an elevated, semi-circular lesion in the lower rectum. Pathological examination revealed a stage IIIb (pT3 N2a cM0) moderately differentiated tubular adenocarcinoma, and he was diagnosed with Fournier's gangrene secondary to rectal cancer. Fournier's gangrene is defined as a necrotizing soft tissue infection that occurs mainly in the perineal area. Although rectal cancer is a relatively uncommon cause of Fournier's gangrene, lower endoscopy serves as a valuable technique for investigating suspected cases of rectal cancer.</p>
