| Abstract: | Two dogs were presented with a history of lameness associated with swelling of one of the digits. Radiographs of the affected digits revealed an irregularly mineralized, smoothly marginated proliferative bone lesion in the distal phalanx of one dog and a destructive bony lesion in the distal phalanx of the second dog. The differential diagnosis included nail bed carcinoma, malignant melanoma, osteomyelitis, and subungual keratoacanthoma. Radiographic findings and no response to medical treatment resulted in amputation and submission of the digits for a histopathologic diagnosis. Histologic examination of the distal phalanx of the digits revealed benign epidermoid cysts associated with either bony proliferation or osteolysis. Excision of the lesions was curative. This report presents the clinical, radiographic, and histopathologic findings associated with intraosseous epidermoid cysts in the distal phalanx of two dogs.
