A rare case of postauricular spontaneous keloid in an elderly patient.

Keloid represents an exuberant wound healing response, usually secondary to trauma, inflammation, surgery, or burns. Spontaneous keloid formation is rare and it is controversial whether it is really spontaneous. It usually occurs in young people, and it is rare in elderly. Its main features are the infiltration of surrounding normal tissue, the rare regression and the evolution over time. We report the case of an 81 -year -old man with unexpected spontaneous keloid lesion in the right postauricular region. The diagnosis was hard to be performed because of the patient's age, the anatomical site of the lesion and the absence of skin trauma or injury history. Only the histological examination allowed us to perform the right diagnosis.
