Henoch-Schönlein purpura associated with pulmonary Mycobacterium avium-intracellulare complex
1Department of Pulmonary Medicine, Matsue National Hospital, Matsue.
Abstract:
A 57-year-old woman presented with bloody sputum and high grade fever. She had been treated for Mycobacterium avium-intracellulare complex (MAC). High grade fever slightly decreased and bloody sputum disappeared after two weeks, but low grade fever persisted. After 3 days of recurrence of bloody sputum, she suddenly complained of palpable pururitic lesions on the bilateral lower extremities with bilateral gonalgia. Although there are some reports of direct skin lesions due to MAC, there are no reports of hypersensitivity vasculitis, Henoch-Schönlein purpura, in MAC. It is necessary to consider MAC infection as a potential cause of Henoch-Schönlein purpura.
