Superficial migratory thrombophlebitis and factor XII deficiency.
A patient with painful migratory erythematous nodules for 7 years is presented. The nodules, which were localized on the lower and upper extremities, progressed to palpable cords. Multiple venograms showed no evidence of deep vein thrombosis. Skin biopsy specimens were diagnostic of superficial thrombophlebitis. There was no evidence of internal malignancy. Extensive evaluation for an underlying hypercoagulable state was remarkable for a factor XII level 17% of normal. The patient was unresponsive to a wide range of treatments. The recalcitrant nature of his disease and lack of deep venous involvement are unique. An underlying hypercoagulable state should be considered when the diagnosis of superficial migratory thrombophlebitis is considered.
