Systemic lupus erythematosus (SLE) is a multi-system inflammatory disorder that has many symptoms. Gastrointestinal symptoms are common, while colonic involvement in the form of ischemic colitis or a colonic ulcer is rare in SLE. The differential diagnosis of ischemic proctitis with ulceration includes an infected ulcer, ulcerative colitis, Crohn's disease, solitary rectal ulcer colitis, malignant tumor, and lupus colitis. Here, we report a 22-year-old male with abdominal pain and diarrhea, who had a huge rectal ulcer that nearly obstructed the rectosigmoid junction. This turned out to be a rare gastrointestinal manifestation of lupus. He recovered after being treated with high-dose oral steroids. Our case demonstrates that a rectal ulcer is a rare, but important, complication of SLE and can be the initial clinical manifestation of the disease.

Sweet's syndrome is a neutrophilic dermatoses characterized by the abrupt onset of fever, leukocytosis and skin lesions that are infiltrated by neutrophils. Most skin lesions are in the form of erythematous tender papules or nodules, usually affecting the upper limbs, face or neck and histologically a dense perivascular infiltrate of neutrophils without vasculitis. Sweet's syndrome can be associated with several disorders, such as inflammatory bowel disease, malignant tumors, and autoimmune diseases including rheumatoid arthritis. We report a case of Sweet's syndrome with associated rheumatoid arthritis. The patient had multiple skin lesions in her face, neck, both upper and lower extremities except trunk, and complained fever, chills and arthralgia. The result of skin biopsy showed mature neutriphil infiltration and leukocytoclasia of dermis without vasculitis, which was compatible with Sweet's syndrome.

Wegener's granulomatosis (WG) classically consists of necrotizing granulomatous inflammation of the upper and/or lower respiratory tract, necrotizing glomerulonephritis, and an autoimmune necrotizing systemic vasculitis affecting predominantly small vessels. We report a case of WG with central nervous system (CNS) involvement. WG is being diagnosed through pulmonary nodule biopsy. A small nodular lesion in the left posterior basal ganglia of brain being highly suspicious for granulomatosis was detected by MRI. After IV pulse cyclophosphamide and oral corticosteroid treatment for over 4 months, clinical manifestations and CNS lesions in brain MRI is improved. WG might have multiple granulomatous lesions which could be misdiagnosed due to malignancy. CNS involvement in WG is rare but careful evaluation is necessary when there are suspicious symptoms or lesions in CNS.
