Uterine tumors resembling ovarian sex-cord tumors have an immunophenotype consistent with true sex-cord differentiation

Seven examples of Clement and Scully's type II uterine tumors resembling ovarian sex cord tumors were studied immunohistochemically with markers of sex cord, steroid cell differentiation (inhibin, O13, A103), or both, and were found to be immunoreactive for one or more of these markers in all cases.
