Systemic lupus erythematosus (SLE) related gastrointestinal vasculitis is a rare condition limited to case studies within the literature however, no cases of rectal gangrene and perforation have been previously described.
A 32-year-old male presented with abdominal pain, vomiting and fevers. CT demonstrated free gas and free fluid around the rectum indicative of a perforation. He proceeded to urgent laparotomy, confirming a diagnosis of rectal infarction and perforation. Uniquely, the involved segment of gangrene extended from the rectosigmoid to the anorectal junction. A Hartmann's procedure was performed. Histopathology confirmed underlying stenosis of the rectal arteries secondary to chronic vasculitis related to the affected areas. The current case is a unique presentation of SLE-related vasculitis. It highlights the need to judiciously investigate SLE patients presenting with surgical acute abdomen.
