In March 2022,a 4-year-old rabbit was sent to the Animal Clinical Teaching Hospital of Northeast Agricultural University for treatment due to a lump between the toes of his right hind limb.Inspection showed a lump between the first and second toes of the right hind limb of the sick rabbit,which was firm to the touch and located under the skin.Surgical excision was performed after evaluation;the rabbit recovered well after surgery.The resected tumor was multiple clumps of 1.5 cm×1.5 cm×1.0 cm to 2.5 cm×2.2 cm×2.0 cm in size;the clumps were firm to the touch and had a white to yellowish white facet.The cells and fibers in the tumor tissue were arranged in bundles or waves,and swirl-like structures could be seen in some areas;the cells were spindle-shaped,and the nucleus was oval or spindle-shaped,which was mixed and intertwined with the fibrous tissue.The diagnosis confirmed it as peripheral nerve sheath tumor.
