title: [A case of lupus erythematosus profundus followed by systemic lupus erythematosus presenting with severe intestinal involvement].
abstract: A 52-year-old female visited the outpatient department of Sapporo Medical University hospital in 1984 due to a refractory rash on the skin of the trunk. Histological findings of a skin biopsy specimen indicated a diagnosis of lupus erythematosus profundus (LEP). The eruption remained quiescent with moderate doses of prednisolone. In October 2003, she was suddenly admitted to our hospital with abdominal pain, fever and bloody stool. Lupus enteritis was diagnosed based on an elevated level of anti-DNA antibody, low complementemia and diffuse edematous change of the intestinal walls on CT scans. Although high doses of corticosteroids resulted in transient improvement, melena developed again on the 24th hospital day. Colonoscopy revealed deep ulceration at the rectum and a gastrografin enema indicated perforation. Accordingly, the involved rectum was resected and an artificial anus was constructed on the 50th hospital day. Examination of the resected specimen by microscopy showed that the ulceration approached at the depth of the subserosal layer with intense infiltration of inflammatory cells around the vessels. The pathogenesis of the rectal lesion might have been due to vasculitis associated with systemic lupus erythematosus (SLE). The disease did not recur under the administration of 10 mg of prednisolone daily until November 2004. Colonic function made a remarkably untroubled recovery after the artificial anus was closed in February 2005. The LEP was generally accompanied by a mild form of SLE. This case seemed to be rare in that SLE was associated with severe lupus enteritis and a refractory rectal ulcer developed from LEP. Patients with SLE and intestinal involvement should be carefully monitored in cooperation with a surgeon.
