Ovarian mature cystic teratoma with florid vascular proliferation and Wagner-Meissner--like corpuscles.

An ovarian mature cystic teratoma featuring florid vascular proliferation and Wagner-Meissner-like corpuscles is presented. The vascular proliferation is analogous to that seen in other tumors having a prominent neural component. The Wagner-Meissner-like corpuscles are viewed as evidence of a specialized type of differentiation of this neural component. To the best of our knowledge, they had not been previously reported in this setting.
