Cutaneous miliary tuberculosis in a renal transplant patient: a case report and literature review.

The incidence of tuberculosis in renal transplant recipients is higher than in the general population. However, the incidence of cutaneous miliary tuberculosis in these patients is very rare. We report a 56-year-old renal transplant Thai man admitted to the hospital with prolong fever, dry cough and multiple small erythematous papules on his extremities. A chest X-ray revealed diffuse miliary infiltration. Mycobacterium tuberculosis DNA was demonstrated in bronchoalveolar lavage fluid by polymerase chain reaction. Histopathology of a skin biopsy showed poorly formed noncaseating granulomatous inflammation in the lower dermis and was positive for many acid-fast bacilli. Miliary tuberculosis of the lung and skin were diagnosed. The respiratory symptom and the skin lesions improved after treatment with anti-tuberculous drugs.
