Vascular nevi may be divided, from the standpoint of radium therapy, into four types: (1) flat angiomas, superficial and level with the skin; (2) flat angiomas, level with the skin but deeply infiltrating the cutaneous and subcutaneous tissue or mucous membrane; (3) angiomas which are elevated to a greater or less degree with smooth and papillated surface; (4) soft and pulsatile angiomas with fluctuating areas, and (5) erectile angiomatous tumors situated under the skin or in the mucous membrane.
Most of the cases that came under our observation belong in the third group, some in the fourth and fifth groups and a few in the second group. The few attempts made to treat the superficial flat angiomas (port wine marks) with radium met with indifferent success and were not continued for sufficient time to warrant comment.
The type of lesion treated in this study may be classed as raised capillary
