Methods The clinical data of melanoma patients diagnosed in the Third Affiliated Hospital of Kunming Medical University/Yunnan Provincial Cancer Hospital from January 2007 to December 2021 was collected, and data on gender, age, lesion location, and incidence trends were analyzed. Results Of the 1203 melanoma patients, 77.3% had primary cutaneous melanoma and 17.3% had primary mucosal melanoma. The age of patients ranged from 11 to 90, with the highest prevalence （82.8%） in the age group of 31-70 years. Acral lentiginous melanoma is more common in men; genital mucosal melanoma is most commonly seen in women （P < 0.05）. Head and neck mucosal melanoma accounted for 55.3% of the total body mucosal melanoma, and the proportion of head and neck mucosal melanoma was 5.58 times higher than that of other parts of the body. Conclusion The melanoma diagnosis rate in Yunnan Cancer Hospital is on the rise. The focus of prevention and treatment in Yunnan Cancer Hospital is melanoma of the limbs and head and neck, especially mucosal melanoma of the head and neck. [ABSTRACT FROM AUTHOR]
