[A case of granulomatous tubulointerstitial nephritis in a patient with pulmonary sarcoidosis].

A clinical observation is presented of a patient with pulmonary sarcoidosis, who was diagnosed with kidney damage after three years with the development of chronic renal failure and the need for replacement therapy. A histological examination of the renal biopsy revealed a granulomatous process in the interstitial tissue, which was regarded as an extrapulmonary manifestation of sarcoidosis. Pulse therapy with glucocorticoids was prescribed and an attempt was made to reduce hemodialysis sessions.
