Multiple eruptive keratoacanthomas, de novo.
An 89-year-old man presented with the sudden eruption of multiple, erythematous papules and nodules on his lower extremities. A skin biopsy specimen showed keratoacanthoma. After 3 months of treatment with topical imiquimod cream, the keratoacanthomas failed to resolve. We review the different clinical subtypes, histologic features, and treatment options for multiple eruptive keratoacanthomas.
