title: [Multinodular keratoacanthoma].
abstract: Multinodular Keratoacanthoma is a variant of keratoacanthoma presenting with large annular plaques localized on the photo-exposed surfaces of the aged people. It is characterized by progressive growth of new nodules of keratoacanthoma at the periphery, while partial or complete spontaneous central healing occurs with scar formation. There is no tendency toward spontaneous regression. Multinodular Keratoacanthoma is quite rare. In our opinion only ten cases can be complied from the literature. We report an additional case in a diabetic 87 year old woman. She was previously affected by a vulvar squamous cell carcinoma. No recurrence was observed four months after the surgical excision.
