Even without any magnification
you can see the tremendous variation in tissue types in this slide.
I am not too sure you'll find much in the way of normal testis. See this slide with the virtual microscope. |

Note the multiple tissue types in this tumor. The picture reveals several gland-like structures lined by a columnar epithelium. There is an intervening stromal material composed of mesenchymal elements that look very embryonic and undifferentiated. This "embryonic" appearance gives rise to this lesion's name. You will see some mitoses and areas of necrosis with accompanying inflammation. In some of the slides, elements of a seminoma are also present. |
