Image Description
Diffuse Large B-cell Lymphoma of the Testis: The peripheral areas show intertubular (interstitial) growth with entrapment of tubules. The neoplastic cells invade the periphery of the tubules, displacing the germ cells and Sertoli cells centrally or completely replacing them. The remnants of atrophic tubules are visible as lighter pink islands in a sea of blue/purple tumor cells at low magnification.
