A 90 year old woman presented with a rapidly growing nodular tumor at the tip of the nose. Clinically, keratoakanthoma was tentatively diagnosed. Histological examination, however, revealed Merkel cell carcinoma. This case supports the necessity of a surgical excision with a subsequent histological examination even when the clinical aspect is suggestive for keratoacanthoma.
