ABSTRACT
Leprosy is a chronic infectious disease caused by Mycobacterium leprae, a microorganism that usually affects skin and nerves. Although it is usually well-controlled by multidrug therapy (MDT), the disease may be aggravated by acute inflammatory reaction episodes that cause permanent tissue damage particularly to peripheral nerves. Tuberculosis is predominantly a disease of the lungs; however, it may spread to other organs and cause an extrapulmonary infection. Both mycobacterial infections are endemic in developing countries including Brazil, and cases of coinfection have been reported in the last decade. Nevertheless, simultaneous occurrence of perianal cutaneous tuberculosis and erythema nodosum leprosum is very rare, even in countries where both mycobacterial infections are endemic.(AU)

O adenoma pleomórfico é um tumor benigno que pose se originar das glândulas salivares, lacrimais e sudoríparas. A localizaçäo nas pálpebras é infrequente. Os autores apresentam um caso de adenoma pleomórfico na pálpebra inferior, com comentários a respeito dos demais casos descritos na literatura
