Uropatía obstructiva como presentación clínica inicial de sarcoidosis: reporte de caso y revisión de literatura.

Sarcoidosis is a multisystemic disease of unknown cause, commonly affecting young and middle-aged adults. It frequently presents with bilateral hilar adenopathy, pulmonary infiltration, and skin lesions; the liver, spleen, lymph nodes, heart, central nervous system, and bone may be affected. A 41-year-old male who began with renal colic, when carrying out the protocol, is diagnosed through CT scan bilateral renal and ureteral lithiasis, however, during the inspection, the lymphadenopathy was highlighted, for which a biopsy was performed in the inguinal node where sarcoidosis is diagnosed. The diagnosis of sarcoidosis, in most of the cases, is given by exclusion because the clinical manifestations are varied. They consist of obstructive or restrictive airway patterns, uveitis, and skin injuries. Urinary symptoms as the initial clinical presentation are rare or unusual. [ABSTRACT FROM AUTHOR]
