ABSTRACT
Introduction. Leprosy is a chronic communicable disease caused by Mycobacterium Leprae that takes two forms depending on the degree of immunity of the patient. Tuberculoid leprosy occurs in patients with high resistance and it shows thickening of cutaneous nerves, anesthesia and cutaneous lesions in the saucer. Lepromatous leprosy is observed in patients with less resistance and affects a large number of body systems with broad plaques, nodules in the skin, iritis, keratitis, destruction of the nasal bone and cartilage, testicular atrophy, peripheral edema and involvement of the reticuloendothelial system.Clinical case. A 13-year-old male from Mexico City and based in this city that began his condition three years ago when he suffered a scratch on his right leg while playing soccer, which when healing became an itchy area and subsequently a hypopigmented spot. A year ago, the same area became an area with cutaneous anesthesia, the sweat test reported anhidrosis, and a smear test was performed that confirmed the biopsy diagnosis that reported perianexial and perivascular dermatitis with lymphocytes and histiocytes compatible with undetermined leprosy. He is currently receiving medical treatment with Rifampicin and Dapsone so he begins to have remission of the lesion gradually.
Discussion. Clinically, leprosy manifests as localized, multiple or disseminated lesions and the histopathology of the skin lesions varies from granulomas to diffuse infiltrations of the skin depending on the immunological status of the patients although in some cases the histopathological analysis may not correlate with the clinical diagnosis.
