Description:Viewed from a right posterolateral perspective, this patient 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). Note the numerous cutaneous erythematous blotchy lesions on the patient’s back, right shoulder, and upper arm. 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.
