Dog-lick–associated verrucous soft tissue lesion induced by Pasteurella stomatis: An unexpected carcinoma-like presentation

Pasteurella species are Gram-negative, non-motile coccobacilli colonizing the oral cavity and upper respiratory tract of cats and dogs. Soft tissue infections after bites, scratches, or trauma are most often caused by Pasteurella multocida. Pasteurella stomatis, although rarely reported, may also colonize humans and present with a spectrum ranging from mild skin infections to sepsis and death. We describe a zoonotic P. stomatis infection presenting as a verrucous tumor-like mass following contact with a household dog.
