				        	 Purpose:To report a case of upper eyelid keratoacanthoma with a cutaneous horn.Case summary: A 59-year-old female presented to our clinic with a rapidly growing, painless mass in the center of the right upper eyelid. A 2 × 2 × 5 mm dark brown conical hyperkeratotic mass and a 7 × 4 mm nodular, nontender mass were palpable on the right upper eyelid. The lesion was isolated from the surrounding tissues and excised completely. Histopathologically, the excised masses showed parakeratosis along with hyperkeratosis of the conical mass and the keratin plug, keratin pearls, and epithelial proliferation in the nodular mass. These findings led to a diagnosis of eyelid keratoacanthoma with a cutaneous horn. 
				        	
				        
				        	Conclusions:Eyelid keratoacanthomas may be accompanied by cutaneous horns and confused with squamous cell carcinomas. The treatment is complete excision, which should be followed by histopathological analysis
