Bone metastasis of undifferentiated pulmonary adenocarcinoma in a cat

In the cat, metastases from primary lung tumors (PLT) to distal bones have been described by Moore & Middleton (differentiated adenocarcinoma) and Pool et al. (squamous cell carcinoma) (16 22). This paper describes the radiological and pathological findings in a cat with metastatic undifferentiated papillary adenocarcinoma. The involvement of the toes was the initial sign leading to veterinary consultation.
