B: Immunohistochemistry positive for placental alkaline phosphatase.
All cases were negative for epithelial membrane antigen (9 of 9) (11,12,14,16) and placental alkaline phosphatase (4 of 4 cases).
The diagnosis of seminoma was confirmed by further immunohistochemical studies (figure 2, C), although the negative staining for placental alkaline phosphatase and CD 117 are considered to be atypical for seminoma.
