Acute onset of systemic lupus erythematosus with extensive gastrointestinal and genitourinary involvement.

Lupus enteritis may occur as an acute presentation of systemic lupus erythematosus (SLE), and is not uncommonly associated with acute uretero-cystitis and/or hydronephrosis. Extensive involvement of the gastrointestinal tract from the stomach to the rectum in acute SLE is uncommon. We describe a 22-year-old Chinese female who presented with acute extensive gastrointestinal and genitourinary involvement who recovered following pulse intravenous methylprednisolone and cyclophosphamide. A high index of clinical suspicion is required to arrive at the diagnosis of SLE where only acute gastrointestinal and genitourinary manifestations are predominant, and other clinical, haematological and biochemical features of SLE are absent.
