Chondroblastoma in Dog ? A Rare Case

Chondroblastoma (CB) is a rare benign chondral tumour characterised by an epiphyseal location in long bones. A four year old Rottweiler male dog was presented with the history of limping on right fore limb and swelling since two weeks as seen by owner. A plain radiograph showed a well-defined lytic defect, measuring 4-5 cm in diameter in the proximal epiphysis of the right ulnar region. The bone biopsy sample was collected and send for laboratory analysis for histopathology.
