Plain-English summary
An 8-month-old male mixed breed cat was found to have a nodule in its left hind leg, which led to a diagnosis of extramedullary plasmacytoma, a rare type of tumor. A fine needle aspiration cytology test was performed, confirming the presence of abnormal plasma cells. The cat also tested positive for feline leukemia virus (FeLV), which can complicate health issues. Unfortunately, the cat's condition was serious, and further examination confirmed the tumor's presence in the muscle. This case highlights the importance of quick diagnostic methods like fine needle aspiration for identifying such tumors in cats.

Abstract
ABSTRACT Extramedullary noncutaneous plasmacytoma (ENP) is a myeloproliferative disorder of plasma cells that rarely affects cats. This paper describes an ENP case revealed by fine needle aspiration cytology (FNAC) of the mass in the skeletal muscle of an 8-month-old, male, mixed breed cat, which had a nodule in the left hind limb. The rapid immunoassay test confirmed the presence of feline leukemia virus (FeLV). The animal necropsy macroscopically showed the nodule came from the semimembranosus muscle. Histopathological examination ratified the cytological findings. Thus, this paper alerts to the existence of plasmacytoma located in the skeletal muscle of feline species. FNAC is a quick and efficient method for diagnosis of ENP.
