Which category includes Leydig cell, Sertoli cell, Granulosa cell, and Mixed tumors?

• A. Germ Cell Tumor
• B. Stromal Cell Tumors
• C. Gonadoblastoma
• D. Lymphoma

Answer: (B)

Stromal cell tumors cover the gonadal supporting tissue that includes sex cord-stromal components. Leydig and Sertoli cells are classic sex cord-stromal elements, and granulosa cells are another key stromal component. Tumors made from these cells can be pure (a Leydig cell tumor, a Sertoli cell tumor, or a granulosa cell tumor) or mixed, meaning they contain more than one stromal element. That makes them all part of the same broader group: stromal cell tumors. Germ cell tumors arise from germ cells, gonadoblastoma is a rare mixed tumor with germ and sex cord-stromal elements, and lymphoma is a lymphoid malignancy, not part of the stromal category.
