ABSTRACT
INTRODUCTION: Due to heterogeneity in the organs involved and a variety of influencing factors, a wide range of clinical manifestations are possible in systemic lupus erythematosus (SLE). In our knowledge, a combination of leg ulcer and dysentery as presenting symptoms of SLE has never been reported previously. PATIENT CONCERNS: A 13-year-old female child presented with a chronic wound over right medial malleolus for 6 months, and passing of watery stool, later mixed with blood, for 4 days. On examination, she had a fever of 38.5°C. Lab reports revealed anemia, thrombocytopenia, proteinuria, and features of urinary tract infection. Renal biopsy showed membranous glomerulonephropathy. She was positive for antinuclear antibodies (ANA) and antidouble stranded DNA (anti-dsDNA). Immunofluorescence revealed reduced C4 and C3 levels. Abdominal ultrasound showed symmetrical circumscribed thickening, and edematous cecum and ascending colon. DIAGNOSIS: The patient was diagnosed with SLE based on the Systemic Lupus International Collaborating Clinics classification criteria. INTERVENTIONS: The patient was treated with prednisolone, hydroxychloroquine, metronidazole, ciprofloxacin, trypsin-chymotrypsin, zinc, calcium, and calcitriol tablets. OUTCOMES: Fever subsided within 3 days of treatment. Gastrointestinal symptoms subsided within 1 week of treatment. On 31 day of treatment, the wound had been reduced and showed features of healing. CONCLUSION: Dysentery and leg ulcers can be the manifestations of SLE. Therefore, SLE should also be considered when a patient presents with such symptoms. Any suspicion of infection in SLE should be treated aggressively with antibiotics.
