Sonographic diagnosis of large-cell calcifying Sertoli cell tumor.

Large-cell calcifying Sertoli cell tumor is a very rare neoplasm of the testis with less than 100 reported cases. It is associated with some genetic syndromes, and it has some features that help to distinguish benign and malign cases. An 11-year-old boy presented with testicular lesions in both testicles. He underwent right radical orchiectomy in another institution and was referred to our hospital for further treatment. The lesions were reported as large-cell calcifying Sertoli cell tumors in our institution. There were multiple hyperechoic lesions with calcifications in the left testis and lesions showed vascularization on Doppler. Sonographic features of these lesions were also suggestive of benign large-cell calcifying Sertoli cell tumor. The lesions were stabile during follow-up. The ultrasonographic appearance of large-cell calcifying Sertoli cell tumor is descriptive and, together with clinical findings, allows differential diagnosis. It can direct patient management, with a more conservative approach. We report a child with large-cell calcifying Sertoli cell tumor who could have been saved from extensive surgery, such as radical orchiectomy, if the tumor had been diagnosed correctly with sonography.
