Plain-English summary

A group of dogs in Ontario developed scaling, crusting, and hair loss on their faces, which led to a diagnosis of trichophytosis, a type of fungal infection. This condition can sometimes be mistaken for pemphigus erythematosus, an immune-mediated skin disease. In these cases, the dogs showed significant skin inflammation and pustules. Treatment details were not specified, but recognizing the correct diagnosis is crucial for effective management.

Abstract

Trichophytosis is a rare diagnosis in dogs in Ontario, but recently 4 dogs with a scaling and crusting, alopecic, facial dermatitis have been so diagnosed. In all cases, the histopathological findings of severe epidermal and follicular interface dermatitis, accompanied by an acantholytic intraepidermal pustular dermatitis suggested an immune-mediated disease.
