Figure 1.

Histopathology demonstrates a tumor with basaloid areas containing tumor cells with scant cytoplasm arranged in cords with peripheral palisading, retraction artifact, and mucinous stroma, transitioning into areas composed of squamous cells containing abundant eosinophilic cytoplasm (original magnification ×20). Transition zones between the basaloid areas (in the bottom portion of the image) and squamous areas (in the upper left portion of the image) are marked with asterisks (*). Bar = 50 μm. BSC, basosquamous carcinoma.
