Histological details of 2 cases of 'Mondor's phlebitis' suggest that we are dealing with a process affecting lymphatic vessels. Fibrin thrombus formation with mycotic organization and capillary recanalization as well as fibromuscular hyperplasia of the vessel wall with infiltration of the surrounding fatty tissue determine the pathogenesis of the disease.
