Abstract:
Objective:To investigate the clinicopathological features, treatment and prognosis of oralmucosal malignant melanoma to provide a reference for clinical practice.
Methods:Data from 19 patients with oralmucosal malignant melanoma were collected, and their clinical manifestations, treatment methods and follow-up results were retrospectively analyzed.
Results:Among the 19 patients, 11 cases (58%) had lesions in the gingiva, 7 cases (37%) had lesions in the palate, and 1 case (5%) had lesions in the tongue, the difference was statistically significant (P<0.05). Eight patients had regional lymph node metastasis with a metastasis rate of 42%, of which 4 cases had multiple site metastasis, and the total number of regional lymph node metastasis sites was 15. Among the 19 patients, 3 cases received only surgery, 4 cases received cryotherapy, and 12 cases received combined surgery, cryotherapy and biological immunotherapy. Pathological examination showed malignant melanoma. The positive rates of S-100, HMB-45 and Melan-A were 95%, 89% and 84%, respectively. Kaplan-Meier survival analysis showed that patients with lesions less than 5 cm2 had a higher survival rate (P < 0.05).
Conclusions: Oral malignant melanomas usually present as black lesions in the oral mucosa, which are prone to metastasis in early stage. The area of lesions may affect the prognosis of the disease. Therefore, the large range of black lesions or masses should be the alert for the clinicians. Oral malignant melanoma patients are usually treated with combined treatment with surgery, cryotherapy and biological immunotherapy.
