General and Systemic Histopathology, C601&C602
    Slide 146: Testicular Lymphoma

    Trust me that this is from a testis.  I see nothing on the slide to help with the identification of the tissue, but I am sure you can appreciate the profound degree of replacement of the tissue with the malignant lymphocytes.

    See this slide with the virtual microscope.

    I am not too sure there is anything approaching "normal" testis on this slide. It would be impossible to tell the tissue source from the picture I have taken. Note the uniform infiltrate of monotonous lymphocytes throughout the entire specimen. Again, the object here is to be sure this tumor is not an embryonal carcinoma or version of seminoma, two common primary lesions of the testis. The treatments are completely different. Use this slide for comparison when studying the other testicular tumors we are about to see.
