Trichoblastoma is characterized as a benign cutaneous neoplasm that originates in the trichoblastic epithelium of the hair bulb. The present report describes the case of a 4-year-old cross breed neutered male cat that had a history of a slow, freely movable, ulcerated, slow growing, solitary cutaneous nodule located on the left scapular region. Histopathological evaluation showed neoplastic cells arranged in cohesive nests or palisades with eosinophilic and scant cytoplasm. Based on the microscopic findings, a diagnosis of trabecular trichoblastoma was made. The treatment of choice consisted of total surgical excision of the mass with safe surgical margins. Tumor recurrence was not observed.
