|This case report describes a highly pruritic, papular and crusted dermatitis affecting the dorsum of a dog and microscopically diagnosed as dermatitis induced by Straelensia cynotis.
Histologically, each papule was characterized by a dilated hair follicle with marked pseudoepitheliomatous hyperplasia, perifollicular mucinosis and an abundant mononuclear infiltration by plasma and mast cells.
Each dilated follicle contained a larval mite.
A therapy including systemic ivermectins and oral antibiotic therapy was initiated, but the clinical response was poor.
To the best of the authors` knowledge, this is the first report of straelensiosis in Portugal, and the second in Europe.
