Abstract
CASE SUMMARY: A 5-year-old female spayed Chinchilla cat presented with a 4 week history of weight loss and inappetence. A thorough clinical investigation confirmed the presence of a distal jejunal mass. Histopathological and immunohistochemical analysis was consistent with a small intestinal peripheral nerve sheath tumour. RELEVANCE AND NOVEL INFORMATION: To the best of our knowledge, this is the first reported case of a small intestinal peripheral nerve sheath tumour in a cat. This case report demonstrates the use of immunohistochemistry in differentiating this entity from other mesenchymal neoplasms. The veterinary literature available in this field is very limited and this report adds a new differential diagnosis to feline patients presenting with an intestinal mass.
