Proteus syndrome: diagnosis and surgical management.
The congenital hamartomatous syndrome known as the "Proteus syndrome" (PS) manifests itself with regional giantism, lymphangiomatous hamartomas, and other variable features. Review of the medical literature shows approximately 50 cases reported to date. Since this syndrome has only recently been defined, the management of these patients has been speculative and often children are not treated. This report summarizes the characteristics of the PS and presents eight additional cases. All of the eight children had regional giantism with macrodactyly and skeletal hypertrophy. Asymmetrical leg length was pronounced in five children. All children had large lymphangiomas, the majority of which involved the trunk. Three of the children have been followed through adolescence, two into late childhood, and three into early childhood. In contrast to previous reports, we believe that early surgical reconstruction is necessary to reduce deformities due to the giantism and the large hamartomas. During extensive excisions, residual abnormal tissue is often needed in the reconstruction and it is not unusual for postoperative leakage of lymph to be prolonged. All of the children in this series have benefited both physically and emotionally from extensive surgical reconstruction.
