Abstract

Granular cell tumor was described in a 7-year-old male Miniature Pinscher. Sublingual mass was surgically removed and submitted for diagnosis. The mass was about 1.8 cm in diameter, firm, tan, and ulcerated. On histopathology, the mass was unencapsulated and infiltrated adjacent tissue and consisted of nest or sheet of round to polygonal, and occasional spindle-shaped cells. The neoplastic cells contain large amount of eosinophilic granular materials in the cytoplasm. Immunohistochemically, the neoplastic cells were positive to neuron-specific enolase but were negative to S-100. The cytoplasmic eosinophilic granules were positive to PAS but were negative to PTAH methods. Based on these results, the mass was diagnosed as sublingual granular cell tumor. No recurrence or metastasis was noted so far since surgery.
