'Mondor's phlebitis'--a lymphovascular process. Light and electron microscopic indications

Area of Science:

• Vascular pathology
• Histopathology
• Lymphatic system research

Background:

• Mondor's phlebitis is a clinical diagnosis of superficial thrombophlebitis.
• The exact pathological process underlying Mondor's phlebitis remains debated.

Observation:

• Histological examination of two cases previously diagnosed as Mondor's phlebitis revealed significant lymphatic vessel involvement.
• Key features included fibrin thrombus formation with mycotic organization, capillary recanalization, and fibromuscular hyperplasia of the vessel wall.

Findings:

• The observed histological changes suggest that the primary pathology affects lymphatic vessels rather than veins.
• The pathogenesis involves thrombus formation, vessel wall changes, and surrounding tissue infiltration.

Implications:

• The findings propose 'lymphangiofibrosis thrombotica occlusiva' as a more accurate pathological term.
• Reclassifying this condition could lead to a better understanding of its etiology and treatment strategies.
