title: Digital gangrene in a patient with primary Raynaud's phenomenon.
abstract: Digital gangrene is not usually associated with primary Raynaud's phenomenon (RP). Its presence should therefore alert the healthcare provider to look for an alternative explanation. A 19-year-old female patient with primary RP developed digital gangrene following surgical management of acute paronychia. The possible mechanism in this patient appears to be the augmentation of the vasoconstrictive response due to the local infiltration of epinephrine mixed with lignocaine prior to the incision and drainage of her infected finger.
