|Description:||This was the left thigh of a patient who had presented to a clinical setting with a case of lepromatous leprosy, and one of its symptoms exhibited here known as erythema nodosum leprosum (ENL). This illness is caused by the bacterium Mycobacterium leprae.|
A possible cause for this pathologic manifestation may be due to the overabundance of antibody production leading to the deposition of immune complexes in the affected tissues, triggering this immunologically-based inflammatory response. Usually these maculopapular plaques crop up between already-existing lepromatous lesions. Numerous red-purple papules, nodules and plaques comprise these lesions.
