Background: Squamous cell carcinoma (SCC) is regarded as one of the most common diagnosis in lesions of the digit, should be included in the differential diagnosis of lesions of the digit, and seems to exhibit a distinct behavior. Metastases in bone tissue are rare. Bones such as tibia, ulna and vertebrae have been reported as carcinoma metastasis sites. However, no reports of carcinoma metastasis in pelvic bones of dogs are available. This report aims at describing a case of distant and unusual metastasis of squamous cell carcinoma in the pelvis of a dog after an attempt of surgical resection of the primary lesion in the digit. Case: A six-year-old male Rottweiler dog was referred to the Veterinary Hospital of the Faculdade de Ciências Agrárias e Veterinárias, Universidade Estadual Paulista, Jaboticabal, Brazil, with a history of a non-healing lesion on the distal medial aspect of the left thoracic limb after amputation of the fi rst digit, which had been performed four months earlier owing to the same problem. Surgical excision of the lesion was performed followed by wound treatment aimed at healing by second intention as an attempt to preserve the limb. Histological analysis revealed a diagnosis of squamous cell carcinoma. There was recurrence of the lesion presented as circular areas with differentiated hemorrhagic tissue amidst the granulation tissue. Another excisional bi
