Acrochordonous plaques in two Bulldogs and a Pug dog.

Acrochordons or fibroepithelial polyps are exophytic to pedunculated tumour-like lesions of the skin reported to occur in humans and animals. We report here a new and unusual presentation of numerous, closely associated acrochordons forming a plaque, preferentially located at the dorsal neck of two Bulldogs and a Pug dog. Histopathologically these plaques were characterized by oedematous to fibrous cores enclosed by normal to moderately hyperplastic epidermis. We propose the name acrochordonous plaque to reflect the clinical lesion and the histopathological appearance of numerous, closely spaced acrochordons. Although the aetiology of these lesions remains unclear, there may be a breed predisposition for Bulldog-like breeds.
