ABSTRACT

In a 62-year-old white woman, submitted to preoperative evaluation for facectomy, urinary alterations were detected. The diagnosis established included left-sided kidney stones and homolateral exclusion. At pre-nephrectomy, interstitial widespread lung disease and thoracic adenopathy were evidenced and their investigation was postponed to after surgery. In the removed kidney, non cascous epithelioid granulomas were found. Later, transbronchial biopsy disclosed this same aspect. The patient was treated with methylprednisolone and presented slight pulmonary improvement, though no amelioration in renal function occurred. Final diagnosis was sarcoidosis with lung, thoraco-lymphatic and renal involvement.

RESUMO

Em uma mulher de 62 anos, branca, em avaliação pré-operatória de facectomia, foram detectadas alterações urinárias, tendo sido firmados os diagnósticos de calculose renal esquerda e exclusão renal homolateral. No pré-operatório da nefrectomia foram evidenciados processo pulmonar intersticial bilateral e adenopatia torácica, cuja investigação foi adiada para após a cirurgia. No rim retirado foram detectados granulomas epitelióides não necrotizantes, o mesmo ocorrendo posteriormente em biópsia transbrônquica. A paciente foi tratada com metilprednisolona, com discreta melhora pulmonar, o que não ocorreu com a função renal. O diagnóstico final foi de sarcoidose com envolvimento pulmonar, ganglionar torácico e renal.
