INTRODUCTION: Mondor's disease is a peculiar form of thrombophlebitis, involving 
a superficial vein in the subcutaneous fat of the breast or anterior chest wall.
CASE PRESENTATION: The author presents a case of a 35-year-old male Japanese 
patient with cord-like induration in the right lateral thoracic wall. This 
lesion was diagnosed as traumatic funicular phlebitis, resembling Mondor's 
disease.
CONCLUSION: Traumatic funicular phlebitis, resembling Mondor's disease, is a 
clinical entity which may give suggestive insight to the etiology of Mondor's 
disease itself.
