Sexual reversal syndrome is a kind of hereditary disease whose chromosome sex is not consistent with gonad sex. The incidence is very low, and pathogenesis is unknown. The related clinical manifestations are different. This paper report a patient with 46, XY chromosome karyotype, but her gender, internal and external genitalia are female, and the right ovary is accompanied by gonadoblastoma and dysgerminoma, in order to provide some new clinical ideas for the diagnosis, treatment and research of sex reversal syndrome.

Dysgerminoma is one of the two most common types of ovarian germ cell tumors. Providing accurate pathologic diagnosis and treatment planning, the prognosis is good even in advanced stages. Pathologic diagnosis is generally straightforward. In microscopic examination, the usual known growth patterns in tumor cells are solid, trabecular, insular and rarely pseudoglandular. In this paper, we reported an advanced ovarian dysgerminoma with different microscopic patterns of growth, including pseudopapillary and macrofollicular structures, in an 18-year-old woman. The patient underwent staging laparotomy and is currently receiving chemotherapy. [ABSTRACT FROM AUTHOR]
