Osteochondrosarcoma of the submandibular
salivary gland of a 4-year-old female Cocker Spaniel. The pearl-like millimetric
formations of bony consistency that can be seen in the image correspond
to foci of infiltration of the salivary gland by neoplastic cells of osseous
and cartilaginous origin, arranged in compact spheres separated by a delicate
conjunctive stroma with identifiable peripheral areas of trabecular bone.
The tumour has completely infiltrated and destroyed the parenchyma of
this salivary gland. In spite of the tumour’s unusual architecture,
the tumour cells exhibited a high level of differentiation.
