Mixed and Unclassified Sex Cord-Stromal Tumors of the Testis
- 3 Downloads
Mixed and unclassified sex cord-stromal tumors are neoplasms with indeterminate differentiation or containing randomly mixed Leydig, Sertoli, and granulosa cells. Although mixed and unclassified are listed separately by the WHO 2016 classification, many experts argue that they can hardly be distinguished from each other.
Both tumors are rare.
Occasional tumors in each category may be malignant.
Grossly the tumor is well circumscribed and yellowish white.
