Plain-English summary
A senior dog with a long-term bacterial ear infection in both ears developed squamous cell carcinomas (a type of skin cancer) on the outer part of its ears. These tumors likely formed due to the ongoing infection affecting the area. Treatment details weren't specified, but it's important for pet owners to monitor any changes in their dog's ears, especially if they have a history of ear infections. Regular veterinary check-ups can help catch issues like this early.

Abstract
Abstract- An aged dog with a chronic, bilateral, bacterial otitis externa developed bilateral squamous cell carcinomas of the pinna. The tumours were located where the pinna would cover the external auditory meatus and probably were induced by the chronic infection. Résumé- Un chien agé souftrant d'otite externe bactérienne chronique bilatérale présenta un épithelioma spinocellulaire bilatéral des pavilions auriculaires. Les tumeurs étaient situées là où les pavilions auraient recourvert le méat auriculaire et furent sans doute provoqués par l'infection chronique. Zusammenfassung- Ein alter Hund mit einer chronischen, bilateralen, bakteriell bedingten Otitis externa entwickelte Plattenepithelkarzinome en beiden Ohrmuscheln. Diese Tumore traten an der Pinna exakt an der Mündung des äußeren Gehörgangs auf, und sind möglicherweise durch die chronische Infektion induziert worden. Resumen  Un perro de edad avanzada que presentaba una otitis externa bilateral bacteriana crónica desarrolló unos carcinomas de células escamosas bilaterales del pabellón auditivo. Los tumores estaban localizados en la entrada del meato auditivo y probablemente fueron inducidos por la infección crónica.
