Plain-English summary
A 7-year-old male cross-breed cat had a hard, white mass about the size of a grape on the outer side of his left front toe. After the tumor was surgically removed, tests showed it was a glomus tumor, which is very rare in cats. This type of tumor is made up of specific cells that are often found around small blood vessels. Since this tumor is uncommon, it's important for pet owners to be aware of unusual growths on their pets and consult a veterinarian for proper diagnosis and treatment.

Abstract
A solitary mass approximately 1.5 x 2 cm located on the outer side of the third digit of the left forepaw of a 7-year-old male cross-breed cat was examined pathologically. The excised tumor mass was hard and white and located within the deep dermis and subcutis. Histopathologically, the mass consisted of a mixed population of small round epithelioid cells arranged in ribbon- or cordlike structures and spindle-shaped cells forming loose irregular bundles in a mucinous stroma. The epithelioid cells were often arranged around small blood vessels. Neoplastic cells were intensely positive for vimentin and alpha smooth muscle actin and negative for keratin, desmin, S-100 protein, and neuron-specific enolase. Based on these pathologic features, the tumor was diagnosed as a glomus tumor, a neoplasm not previously reported in cats and extremely rare in animals.
