          Abstract

          A associação de lúpus eritematoso sistêmico e porfiria, embora rara, é conhecida de longa data. Ela obriga o médico a realizar um cuidadoso diagnóstico diferencial das lesões bolhosas nesses pacientes e tomar cuidados com a prescrição de certas drogas, como a cloroquina. Esta, nas doses habituais para tratamento do lúpus, pode causar hepatotoxicidade em pacientes com porfiria. Descreve-se o caso de uma paciente com lúpus que desenvolveu lesões bolhosas compatíveis com porfiria cutânea tardia.

          Translated abstract

          The co-existence of systemic lupus erythematosus and porphyria although rare has been known for a long time. This association forces the physician to make a careful differential diagnosis of the bullous lesions that might appear in such patients and to be careful when prescribing certain drugs such as chloroquine. This drug, when used in the regular doses for treating lupus, may cause hepatotoxicity in patients.suffering from porphyria. It is described here the case of a patient with lupus who developed bullous lesions compatible with porphyria cutanea tarda.
