case_images: The histopathology revealed metastatic poorly differentiated squamous cell carcinoma with focal positivity for beta-hCG (Figures 4 and 5).

case_images: The histopathology revealed metastatic poorly differentiated squamous cell carcinoma with focal positivity for beta-hCG (Figures 4 and 5).
case_images: Immunohistochemistry showing cells that stain positive for P63, highly suggestive of squamous cell carcinoma.
