ABSTRACT

We described a case of melanoma located in the right phalanx in a dog. A defined bitch,11 years old, was referred to the Medical Clinic of the UFCG Veterinary Hospital witha history of increased volume at the distal end of the right thoracic limb. After theclinical evaluation and surgical correction, the material was sent to the Laboratory ofAnimal Pathology (LPA), Veterinary Hospital (HV), Federal University of CampinaGrande (UFCG) – PB. Macroscopically, the mass was nodular, skin-coated, measuring10 x 7.0 x 6.5 cm and ulcerated central area 5 cm in diameter. When cutting, it exhibiteda blackish, multilobular and firm surface. Microscopically, a thickly cellular, infiltrativeand non-encapsulated tumor mass was observed in the epidermis. This paper reports acase of digital melanoma, diagnosed by histopathological examination.
