目的探讨皮肤恶性黑素瘤流行病学特点。方法分析38例患者的临床资料。结果73.7%的皮肤恶性黑素瘤发生于肢端;47.4%原发部位曾有先天性痣。近年来面、颈部皮肤恶性黑素瘤比例增加,足部减少;就诊病人多为Clark中后期,生存率低。结论肢端是皮肤恶性黑素瘤最常见的发病部位,大多原有先天性痣,外伤是发病重要诱因。近年来皮肤恶性黑素瘤人数增加,且预后极差。
Objective To investigate the epidemiological characteristics of cutaneous malignant melanoma. Methods Clinical data of 38 patients were analyzed. Results 73.7% of cutaneous malignant melanomas occurred in the acral; 47.4% of primary sites had congenital hernia. In recent years, the proportion of malignant melanoma on the face and neck has increased, and the foot has decreased; the patient is mostly in the middle and late Clark, and the survival rate is low. Conclusion Acromegaly is the most common site of cutaneous malignant melanoma. Most of them are congenital convulsions. Trauma is an important cause of the disease. In recent years, the number of malignant melanomas of the skin has increased and the prognosis is extremely poor.
