Tuberculosis of the colon in a kidney transplant patient.
A 58-year-old woman experienced recurrent fever episodes after kidney transplantation. She was treated with antibiotics because of suspicion of staphylococcus infection. Abdominal pain combined with haemorrhagic diarrhoea occurred eight months after transplantation. A barium enema revealed a stenotic process in the middle part of the ascending colon mimicking carcinoma, and hemicolectomy was consequently performed. Histological examination revealed tuberculosis with little granuloma formation and abundant acid-fast tubercle bacilli in the mucosa and submucosa, and only slight perigranulomatous reactions. The patient was successfully treated with triple antituberculous chemotherapy without deterioration of allograft function. Tuberculosis should be suspected in immunosuppressed patients suffering from pyrexia of unknown origin, even when chest X-ray is normal.
