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.

RESUMO O melanoma uveal é raro na infância. Relata-se um caso de melanoma da coróide em criança de 5 anos que se manifestou por baixa visão, olho vermelho e dor. Os exames ultrassonográfico e tomográfico mostraram tumor intraocular extenso e o exame histopatológico mostrou se tratar de melanoma do tipo epitelióide de pequenas células. São enfatizados os fatores prognósticos do melanoma coroidal e a raridade do melanoma uveal na criança.
