Lymphangioma circumscriptum: review and evaluation of carbon dioxide laser vaporization.

Three cases of the classical form of lymphangioma circumscriptum are described to illustrate the varied clinical manifestations of these lesions. The anatomy and physiology of cutaneous lymphangiomas are reviewed and their classification is clarified as a guide to their management. Treatment was sought by these patients in order to alleviate complaints of copious transudate of lymphatic fluid and chronic relapsing cellulitis. All three were treated with carbon dioxide laser vaporization with good to excellent cosmetic results and complete resolution of their symptoms. Carbon dioxide laser vaporization may be a useful alternative to frequently unsuccessful traditional surgical forms of therapy for selective cases of classical lymphangioma circumscriptum.
