Proteus syndrome, Cerebriform connective tissue nevus, Endovenous radiofrequency ablation


We reported a case of a 10 year-old Thai boy diagnosed as Proteus syndrome, presented with progressive enlarging of extremities with asymmetric distorting of the feet and toes. Skin examination showed marked thickening of the soles without characteristic cerebriform appearance, and well-defined purplish plaques with capillary-microcystic lymphatic malformation on the right hip and thigh. MRI/MRA of extremities showed disproportionate overgrowth with combined lymphatic-venous malformation at the right VNUS® Radiofrequency Generator Model RFG2 (VNUS Medical Technologies Inc., San Jose, California, USA and foam sclerotherapy after ablation as an adjunctive treatment for the venous malformation of the right leg with favorable outcomes.
