[Bockenheimer's syndrome. A clinical report].

The authors report the clinical case of a 12-year-old boy with an extensive superficial venous network in almost every area of the body, present since birth and worsening in recent months, with the occurence of superficial venous thrombosis. No other changes on physical examination were noted, no symptoms and no analytical or imaging findings were found. Histological examination of the lesions revealed ectatic superficial veins without any proliferation of endothelial cells and the amount of elastin in the walls of these veins was decreased. The patient was diagnosed as a Bockenheimer's syndrome. The main features of this rare syndrome are described and discussed.
