|Title:||Panniculitis in tuberculosis: A clinicopathologic study of nodular panniculitis associated with tuberculosis|
|Citation:||International Journal of Dermatology. Vol.37, No.5 (1998), 361-363|
|Abstract:||Background Certain types of panniculitis, erythema induratum of Bazin and erythema nodosum, have been well documented as tuberculids. Many histopathologic diagnoses of panniculitis have been reported in tuberculosis patients. This study investigates the correlation between underlying tuberculosis and clinicopathologic findings of panniculitis. Methods We retrospectively reviewed the clinical files of histologic-proven panniculitis cases at the Dermatologic Clinic, Siriraj Hospital from January 1992 to December 1995; only cases with active tuberculous foci were analyzed. Results The incidence of panniculitis caused by tuberculosis was 8.2%. The ratio of men to women was 1:1. The mean age of onset was 35.3 years. The average duration of the nodules was 35.5 days. There was a history of contact tuberculosis in 16.6%. Constitutional symptoms and a strongly positive purified protein derivative (PPD) reaction were found in 66.6%. Chest roentgenograms were abnormal in 83.3%. The erythrocyte sedimentation rate was elevated in all tested cases. The histopathologic diagnoses were nodular vasculitis (33.3%), erythema nodosum (50%), and cutaneous periarteritis nodosa (16.4%). The panniculitis lesion responded to standard antituberculous regimens in 4.6 weeks, on average, with residual hyperpigmentation. Conclusions In panniculitis patients, clues for the investigation of tuberculosis included constitutional symptoms, elevated erythrocyte sedimentation rate, and abnormal chest roentgenograms. Histopathologic changes of panniculitis did not seem to correlate with underlying tuberculosis. The clinician should be aware of the tuberculosis, however, and should carefully search for active foci in all panniculitis patients.|
