title: Malignant melanoma simulating a seborrheic keratosis: a case report.
abstract: This is a case report of malignant melanoma presenting with both clinical and histopathologic features of a seborrheic keratosis. Not a rare phenomenon, this report emphasizes the importance of biopsy to evaluate apparent seborrheic keratoses. We believe that this phenomenon is best considered a presentation of melanoma. Diminished routine histopathologic evaluation of apparent seborrheic keratoses may well increase the number of mistaken diagnoses in such cases.
