[A case of polyangiitis overlap syndrome].
A 25 year old man was admitted to our hospital on June 1, 1989 because of general fatigue and pleural effusion. He had noticed purpuras and nodules on his bilateral lower legs in July 1988. He was admitted to Nihon University Hospital and was diagnosed as allergic granulomatous angiitis. Methylprednisolone was administered. In March, 1989, a nodular shadow was detected in his lung CT films. From the findings of TBLB a granulomatous lesion was suspected. However, his clinical course was rather stable so he was discharged from the hospital. Two months later, he was suffered from fever and general fatigue. On his chest X ray film pleural effusion was detected in the lower part of his left lung. The nodular shadow was increasing gradually. Laboratory findings on his admission showed leukocytosis, thrombocytosis, elevated CRP and a high titer of RA factor. He was diagnosed as hypersensitivity angiitis in a broad sense based on his biopsy findings of the skin lesion. Furthermore, the diagnosis of an early stage of Wegener's granulomatosis (WG) or limited type of WG was also made from the clinical course of his lung lesion. The combination therapy with cyclophosphamide and methylprednisolone was started. It was so effective that the nodule of his left lung was almost disappeared. It seems that this case is one of the polyangiitis overlap syndrome proposed by Fauci.
