A case report of ovarian sex cord-stromal tumor, unclassified type / 부인종양

ABSTRACT

Unclassified type occupies about 5 to 10 percent of all ovarian sex cord stromal tumors. Diagnosis is very difficult and subjective because tumors show insufficient differentiation to ovarian or testicular line or display insufficient findings to diagnose as a gynandroblastoma in spite of divergent differentiation. To our knowledge sixty-two cases have been reported in the pathology literatures as yet. The behavior of this group of tumors has not been adequately studied but is similar to granulose cell tumors or Sertoli-Leydig cell tumors. We present a case of unclassified sex cord-stromal tumor which has been experienced in our hospital with brief review of the literature.
