Numerous neoplasms may affect the bone tissue of dogs and cats.

Bone tumours are classified as:

  • primary (malignant or benign), when the tumour originates, in primis, from bone tissue  
  • secondary, in the case of:
    • metastatic dissemination to the bone, caused by neoplasms located elsewhere or by primary bone tumours;                                                                          
    • secondary bone invasion, caused by the contiguity between tumour and bone.   
Primary bone tumours

Malignant

  • Osteosarcoma
  • Chondrosarcoma
  • Fibrosarcoma
  • Haemangiosarcoma
  • Multilobular tumour of bone
  • Giant cell tumour
  • Malignant mesenchymoma
  • Lymphoid tumour and multiple myeloma
  • Malignant fibrous histiocytoma
  • Liposarcoma

Benign

  • Multiple cartilaginous exostoses
Secondary bone tumours

Metastatic

  • Haematogenous metastatic spread to the bone of mammary tumours, bladder tumours, urethral tumours, prostatic tumours, carcinoma of the para-anal sinuses, bone tumours

Invasive, infiltrative

  • Spread of the tumour by contiguity to adjacent bone structures  
  • Neoplasms of the oral cavity (melanomas, carcinomas, soft tissue sarcomas, odontogenic tumours)                                                       
  • Intranasal neoplasms (carcinomas, sarcomas, lymphomas)                                                   
  • Soft tissue sarcomas (synovial sarcoma, myxosarcoma, histiocytic sarcoma)               
  • Ungual tumours (melanoma, carcinoma)
