Lymphangioma of the upper extremity.

Lymphangioma of the upper extremity is rare; its treatment is unstandardized. We reviewed five female and one male patient with cavernous lymphangioma of the hand and forearm. Each of them underwent at least one surgical procedure. Five patients had satisfactory results with cosmesis and hand function. Satisfactory results are expected in those treated initially in early childhood, as most lymphangiomas tend to increase gradually in size and infiltrate previously uninvolved normal tissues.
