Plain-English summary
A 9-month-old male mixed breed cat was found to have aggressive fibromatosis, a type of tumor-like growth, affecting his right forearm and extending to his shoulders and jaw. The area was filled with fibrous tissue and showed signs of rapid growth. Tests indicated that the abnormal cells were related to fibroblasts, which are cells that help form connective tissue. This condition may be linked to a virus that can cause cancer in cats. Treatment details were not specified, but early intervention is crucial for managing such aggressive growths.

Abstract
A case of aggressive fibromatosis (extra-abdominal desmoid) found in a 9-month-old male mixed breed cat is described. The right forearm was almost completely effaced by fibrous tissue and there were some tumours in the area from the shoulders to the mandible. These tumour-like tissues were composed of abundant collagen fibres and sparse numbers of well-differentiated fibroblasts, whereas their growing pattern was aggressive and non-encapsulated. There was dense growth of immature fibroblasts and multinucleated giant cells in some areas. Vimentin immunohistochemistry and electron microscopy suggested that the giant cells had close relation to the fibroblasts, and such areas may be the sites of cell proliferation. This case is different from nodular fasciitis and may be a proliferative disorder induced by feline oncogenic retrovirus.
