Sertoli-cell tumor in an 8-years-old boy with Peutz–Jeghers syndrome. Transverse (a), longitudinal (b) gray-scale B-mode and transverse color Doppler (c) US of the testis. Images show a hypoechoic nodule mostly calcified with irregular calcifications (blue arrow) causing posterior shadowing and artifacts on color Doppler imaging. US, ultrasonography. The child presented with acceleration of his growth and gynecomastia. Later, he developed nasal polyps and mucocutaneous pigmentation and Peutz–Jeghers syndrome was confirmed. The patient underwent conservative surgery.
