Theories about the nature of cavernous hemangiomas have been reviewed. Most authors believe that such vascular tumors are congenital. The influence of pregnancy on the growth of these tumors was exemplified in a case report, and explanatory mechanisms were offered. Occurrences of cavernous hemangiomas that involve the foot were reported in the literature, ranging from 4.9% to 28.5% of all cases reviewed. X-ray findings of phleboliths and the importance of angiography in planning treatment were emphasized. In the authors' case report, a satisfactory surgical result was obtained in a plantar foot lesion that would otherwise have required amputation.
