The source of the spindle cell component, stromal or epithelial, is argued. Present consensus is that the source is epithelial and that the various tumor cell forms encountered in the stroma all stem from the squamous epithelium: a truly pleomorphic phenomenon. Our cases below demonstrate this apparent transformation from squamous to spindle cell forms. Carcinosarcoma and collision tumor warrant differential discussion.
