title: [Role of the pathologist in the diagnosis of palpebral keratoacanthoma: case report and literature review].
abstract: We report the case of a keratoacanthoma of the lower lid in a 14-year-old girl posing diagnostic difficulty with differentiating the lesion from a verrucous squamous cell carcinoma on histologic examination of an incisional biopsy. It was only upon complete excision of the tumor that the diagnosis of keratoacanthoma could be made and that of malignancy ruled out. We discuss the clinical and histologic diagnostic criteria for keratoacanthoma and assert that wide biopsy is essential for adequate morphologic study to enable better therapeutic management.
