Cryofibrinogenemia associated with polyarteritis nodosa.
We report the case of a 77-year-old woman with biopsy-confirmed polyarteritis nodosa (PAN) associated with cryofibrinogenemia presenting with polyarthralgia and digital gangrene induced by cold exposure. The clinical manifestations and parameters measured by laboratory markers including cryofibrinogen responded well to corticosteroid therapy. To our knowledge, the case of the combination of PAN and cryofibrinogenemia has not been reported. Our case indicates that cryofibrinogenemia might be associated with PAN. The PAN patients with cold-induced symptoms should be screened for cryofibrinogen.
