We report the case of a 48-year-old male with a 2-month history of migratory polyarthralgia, and myalgia associated with fever and weight loss; one episode of bilateral testicular pain; and unilateral pulsatile headache with thickening of the left temporal artery suggestive of temporal arteritis. The patient evolved with spontaneous left perirenal hematoma, splenic infarcts, and oliguric acute renal failure. Treatment included prednisone and cyclophosphamide. The left temporal artery and the quadriceps muscle were biopsied. Clinical, laboratorial, and radiological findings, as well as the intercurrences, led to the diagnosis of polyarteritis nodosa.

We report a case of adult-onset Still's disease in a female patient with fever, myalgia, vanishing rash and bilateral inguinal lymphadenopathy, diagnosed after extensive workup to exclude other rheumatic, infectious and neoplastic diseases. The patient initially responded to corticosteroid therapy, but progressed to increased lymph nodes size that when biopsied, revealed serous ovarian adenocarcinoma. To our knowledge, this is the first report of ovarian neoplasm associated with adult-onset Still's disease.

O acometimento pulmonar na doença inflamatória intestinal é raro e não está bem caracterizado. Relatamos os casos de duas pacientes com sintomatologia pulmonar inespecífica, em tratamento prévio de doença inflamatória intestinal – doença de Crohn (caso 1) e retocolite ulcerativa (caso 2). Os achados tomográficos foram compatíveis com pneumonia intersticial usual (PIU). Foi realizada revisão da literatura sobre o assunto.

A 27-year-old male patient presented with respiratory symptoms, bilateral enlargement of the cervical lymph nodes and enlarged liver. In the imaging studies, bilateral enlargement of the hilar nodes was observed, together with pulmonary infiltrate. The patient was submitted to lung and liver biopsies, which revealed noncaseating granulomas. The clinical, radiological and histopathological findings were consistent with sarcoidosis and lymph node amyloidosis. The combination of sarcoidosis and amyloidosis has rarely been reported.
