“…6 The first review of the literature on leiomyosarcomas involving arteries and veins was by Kevorkian and Cento, 10 who in 1973, identified eight tumors, of a total of 86 cases, originating in the systemic arteries, three of them considered doubtful. The second review of the literature was made by Briggs and coworkers, 11 who in 1990, while observing a popliteal leiomyosarcoma, added eight more observations to the five cases described by Kevorkian and Cento, 10 for an overall total of 13: four of the femoral artery, three of the common iliac artery, 10,12,13 two of the popliteal artery, 9,11 one of the aorta, 14 one of the axillary artery, 15 one of the internal mammary artery, 9 and one of the inferior mesenteric artery. 9 The most recent review was by Giangola and coworkers 8 (1995), who described one case of subclavian leiomyosarcoma and added two other findings of popliteal leiomyosarcomas 1 and one case of superficial femoral leiomyosarcoma, 16 bringing the overall number of described cases to 17.…”
