DISCUSSION
Many have suggested PROTEUS SYNDROME. The common findings in this syndrome are limb enlargement with large, cystic spaces in the soft tissues and overgrowth that may involve the entire body or may be localized but the hemangiomata are focal and commonly there is macrocephaly.
So the question is: Maybe a HEMANGIOMA ? This is a common, benign, vascular tumor. These tumors are vascular hamartomas, some of which can have a lymphangiomatous component but sonographically are solid in appearance.
Many thought of LYMPHANGIOMATA. These are abnormalities of the lymphatic vessels characterized by cysts within soft tissues usually in nuchal region. These are usually cystic with septa.
A few evoked a MAFFUCCI SYNDROME. It is a rare disease that consists in osteochondromatosis with hemangiomata and the incidence of chondrosarcoma in this disorder is 17-30%.
Finally, many people made the correct diagnosis of KLIPPEL TRENAUNAY WEBER SYNDROME. This syndrome is characterized by large, cutaneous hemangiomata with hypertrophy of related bones and soft tissues, resulting in gigantism of the affected limb. This case is that very characteristic and illustrative of this uncommon syndrome
