(a) Dorsopalmar view of the left and right thoracic limbs, (b) lateral view of the left thoracic limb and (c) lateral view of the right thoracic limb. The arrows indicate the swelling and associated fragment of the third phalanx of the first digit of the left manus. P3 fragments of consistent size and shape are visible in each previously partially amputated digit

Dorsopalmar and mediolateral manus radiographs revealed P3 fragments present in each partially amputated digit (Figure 1).
(a) Ventrodorsal, (b) left lateral and (c) right lateral thoracic radiographs. No evidence of primary or metastatic neoplasia was identified

To further assess the cat for potentially metastatic disease, three-view thoracic radiographs were also evaluated (Figure 2).
Histopathology of the neoplasm arising from the distal phalanx of the first digit of the left manus. Spicules of unmineralized osteoid and neoplastic bone are present. Anisocytosis and anisokaryosis are moderate with a mitotic count of three mitotic figures in 10 high-powered fields. Stained with hematoxylin and eosin, x 30 magnification

Anisocytosis and anisokaryosis were moderate, the mitotic count was three mitotic figures in 10 high-powered fields and osteolysis of the cortical bone was identified (Figure 3).
