case_images: fig1
case_images: A few of the glands were angulated and concerning invasion but lacked a definitive desmoplastic response (Figure 1).
case_images: Areas of trabecular growth composed of Sertoli cells with ovoid nuclei, punctate nucleoli, and nuclear molding; H&E at 400x.

case_images: fig2
case_images: The predominant cell population was characterized by ovoid nuclei lacking appreciable grooves, lightly basophilic cytoplasm, and punctate nucleoli consistent with Sertoli cells (Figure 2).
case_images: Retiform pattern with "staghorn" slit-like tubules; H&E at 100x.

case_images: fig3
case_images: A distinct retiform pattern was also identified consisting of irregular networks of elongated and slit-like tubules with a "staghorn" appearance (Figure 3).
case_images: Nests of Leydig cells with abundant eosinophilic cytoplasm and round nuclei; H&E at 400x.

case_images: A second population of Leydig cells with round nuclei and abundant eosinophilic cytoplasm was interspersed throughout the neoplasm (Figure 4).
