[Thrombosis and phlebitis of superficial veins. Differential histopathologic diagnosis].

Primary thrombosis and phlebitis with secondary thrombosis of superficial veins are frequent. A biopsy may be performed if the clinician suspects an underlying systemic disease. The pathologist must be aware of the different types and their etiology because the further diagnostic and therapeutic procedures depend on his evaluation. The different types of primary thrombotic and primary phlebitic disorders are described and their possible etiology is discussed.
