28-year-old patient presenting with left testicular pain (significant left varicocele during the exam). Typical LCT 12 × 9 mm on B mode us (a) and color Doppler (b) discovered on the right testis. Well-defined lobulated solid lesion moderately hypoechoic and homogeneous echo structure with normal adjacent pulp and absence of microlithiasis. The lesion is hyper vascularized with a mixed peripheral and internal pattern. (c) From left to right: Macroscopic view of the patient’s LCT after enucleation. The typical “golden brown” color of the lesion often allows the surgeon and the pathologist to confirm the diagnosis during surgery. HE × 30 Hematein–Eosin coloration showing a high cellular density with no necrosis. HE × 40 with an endothelial cell marker anti CD-31, showing a rich vascularization of the tumor. Courtesy of Pr S.
