OBJECTIVE Glypican-3 (GPC3) is a membrane-bound heparan sulphate proteoglycan. Glypicans are predominantly expressed during development in cell- and tissue-specific manners and act as co-receptors for many heparin-binding growth factors, playing important roles in cell growth and differentiation.

Canine Malignant Peripheral Nerve Sheath Tumors (MPNSTs) are uncommonly reported in the ulnar, since they are underestimated relative to the more common spindle cell tumours of soft tissue. In dogs, MPNST accounts for 27% of nervous system tumours. In man, MPNST represents 5-10% of all soft tissue

Canine gastrointestinal stromal tumors (GISTs) are a recent subtype of gastrointestinal spindle cell tumor recognized with the increasing use of immunohistochemistry. To our knowledge, no imaging features have been described in immunostochemically confirmed canine GISTs. The objective of this
