Henoch-Schonlein Purpura in a Disseminated Tuberculosis Patient / 대한소화기내시경학회지

ABSTRACT

Henoch-Schonlein purpura is a systemic leukoclastic vasculitis and involves small vessels resulting in vasculitis. Major pathogenetic mechanism of Henoch-Schonlein purpura has not been still elucidated. Possible causes, however, may be associated with viral infection, bacterial infection, exposure to drugs and toxins, systemic diseases and carcinomas. Henoch-Schonlein purpura rarely develops in patients with tuberculosis, though there have been some reports on the development of this syndrome during antituberculous therapy. A 24-year-old man was admitted to our hospital because of diffuse abdominal pain, lower leg purpura and disseminated tuberculosis involving lung, duodenum, colon and lumbar spine and diagnosed as Henoch-Schonlein purpura with disseminated tuberculosis. Henoch-Schonlein purpura developed before antibuberculous therapy and antituberculous treatment was effective both in disseminated tuberculosis and Henoch-Schonlein purpura. We concluded that disseminated tuberculosis might be a cause of Henoch-Schonlein purpura.
