Vascular patterns of testicular tumors: a microangiographic study.
A microangiographic study of 12 cases of testicular tumors was done. In seminoma the blood supply was meager and centripetal, and embryonal carcinoma of adult type was hypervascular with coiling vessels. Vascular patterns of embryonal carcinoma of infants were sinusoidal. Choriocarcoma was hypervascular and there were multiple defects within vessels by its invasion. In a teratomatous cyst vessels of the wall were sometimes irregular, as indicated by surviving teratomatous elements, while in an epidermoid cyst fine vessels of the wall ran parallel in a regular manner.
