Testis-sparing surgery of unilateral testicular large-cell calcifying Sertoli cell tumor: a sporadic case.

Testicular sex cord-stromal tumors constitute a small portion of all types of testicular tumors. Only 1% of these tumors are pure Sertoli cell tumors. Sertoli cell tumors have three identified subgroups: large-cell calcifying (LCCSCT), sclerosing Sertoli cell and general type. Up to 40% of LCCSCT are associated with the genetic syndromes like Carney complex, Peutz-Jeghers syndrome. These lesions are usually benign, only 17% of the cases show malignant behaviour. Herein, we report a case of unilateral LCCSCT in a 37 year-old man without any hormonal symptoms or inherited diseases which was succesfully treated with testis-sparing surgery.
