Abstract

The most common forms of nonmelanocytic skin cancer (NMSC) are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The growing incidence of skin cancer in the Republic of Korea has sparked increasing scientific interest in these types of tumors. In the case described herein, multiple NMSCs occurred asynchronously in various areas of the body in a single patient. A 67-year-old man presented with an ulcerative lesion on the right retro-auricle and multiple keratinized masses on the back and face. The right retro-auricular lesion was diagnosed as BCC, and the keratinized masses on the patient’s back and face were diagnosed as SCC. He subsequently presented with numerous pigmented skin lesions on the forehead, temple, pre-auricle, neck, right forearm, right hand, and both thighs. One lesion on the neck was diagnosed as BCC, and five lesions on the right hand and forearm were diagnosed as SCC. The patient was also diagnosed with supraglottic SCC and external auditory canal SCC. An otolaryngologist performed radical excision of the primary SCC. Suspected skin cancer lesions observed on the face and both ears were diagnosed as SCC. Patients with multiple NMSCs are at an elevated risk for additional skin cancers, making periodic follow-up important; furthermore, all suspicious lesions should be biopsied.
