Eruptive keratoacanthoma with an internal malignant neoplasm.

A 65-year-old woman had hundreds of tumors on the sun-exposed portions of her body and similar lesions in her mouth. All biopsy specimens showed changes consistent with the diagnosis of keratoacanthoma. Further examination of this patient disclosed an asymptomatic ovarian carcinoma. To the best of our knowledge, this is the second case of the rare disorder of eruptive keratoacanthoma to occur in a patient with an internal malignant neoplasm.
