Abstract
|
|
|
|
Mucosal malignant melanoma is an uncommon tumor of the head and neck, and patient cannot easily recognize the lesion. Most patients are diagnosed with advanced lesions, and the 5-year survival rate is very low. Therefore, intraoral pigmented lesions require an incisional biopsy for differential diagnosis from malignant melanoma. As the size of the tumor increases, lesion showing vertical growth and lymph node metastasis increases, and the prognosis becomes poor. In this study, we report a case of mucosal malignant melanoma in the oral cavity that shows radial growth and no lymph node metastasis despite its relatively large size.
