Case Description- A two-year-old female goat with a dark mass on the left hoof was referred to veterinary clinic of Shahid Bahonar University of Kerman.
Clinical Findings- A large black and hemorrhagic tumor-like tissue was observed on the left hoof. The epidermis was intact and hairless.
Treatment and Outcome- Considering the good body condition of the patient, the mass was removed surgically. Cefazoline (20 mg/kg/IM, Jaberebne Hayyan laboratory, Iran) was administered every 12 hours for 5 days. Histopathologic examination showed small spindle cells with intracytoplasmic melanin granules in dermis and dermal melanocytoma was confirmed.
