Thrombophlebitis of the thoracoepigastric system of veins is a benign disease 
and, despite its localized involvement and presentation, the condition is known 
as Mondor disease (MD). A transverse incision made on the thoracoabdominal wall 
divides the axially arranged superficial veins at a right angle and the presence 
of unidirectional valves prevents retrograde blood flow, leading to stasis and 
thrombus formation. The incidence of MD in oncologic breast cases and aesthetic 
mammaplasties is reported to be 0.95% and 1.07%, respectively. Siliconeadenitis 
of axillary nodes, on the other hand, is uncommon and has only been reported 
occasionally. Extensive MD of the left axilla and inner arm is presented 
following excision of axillary nodes secondary to siliconeadenitis after 
cohesive gel silicone breast implant rupture.
