Squamous cell carcinoma in laying hens
Samples were submitted of two laying hens with multiple skin lesions on the back, neck and limbs. The lesions were circular, prominent and crusty. Veterinarians suspected of Marek's Disease or Avian pox.
The histopathological study showed that the lesions corresponded to a malignant neoplastic proliferation of skin cells, squamous cell carcinoma, also known as avian keratoacanthoma.
