Sexcord/ stromal ovarian tumors may be classified according to WHO into 3 subtypes: pure stromal tumors, pure sexcord tumors, mixed stromal and sexcord tumors. Histological classification of sexcord-stromal ovarian tumors includes granulosa stromal cell tumors, sertoli leydig cell tumors, gynandroblastoma, and unclassified.
