This disease is characterized by a hypertrophy and new growth of lymph capillaries, characterized by circumscribed, elevated, crowded vesicles filled with lymph. As a general rule, the disease begins early in life, so may be due to a congenital defect. As a general rule, there is but one patch present, and this usually occurs upon the limbs, neck, or upper portion of the body. The vesicles are firm and not easily ruptured. The pathology has been well studied by Gilchrist.9 These lesions can be easily removed with the actual or electric cautery.
