There is a gentleman with a black mole on his nose, looked for a fortune-teller said that it was a “fortune mole”, with the stock market soaring, as a stockbroker’s natural fortune, and the mole on his nose suddenly “skyrocketed”, increased a lot, and he thought it was a symbol of good fortune for himself! He thought it was a symbol of his good fortune, but he came to the Otorhinolaryngology Department of the hospital for consultation only after bleeding when he washed his face in recent days. After a detailed examination by the doctor, this “black mole”, which was originally thought to be able to bring good luck, was diagnosed as basal cell carcinoma. Basal cell carcinoma occurs in 70%～90% of the cases in the head and face (external nose and perinasal area are the most common), which is easy to cause damage to the appearance and has a slow onset and is not easy to be detected at an early stage and delayed in diagnosis and treatment, thus resulting in a considerable number of patients with functional deficiencies and a heavy burden on social and psychological life, therefore, it is of great significance to strengthen the understanding and prevention of the disease.
