Dentists may encounter pigmented lesions in routine clinical practice. In most cases, the lesions are asymptomatic and benign in nature; however, rarely, a pigmented lesion can be a sign of malignancy. We report a case of malignant melanoma of the maxillary gingiva to highlight the importance of biopsy and periodic follow-up of patients with unusual focal pigmented lesions in the oral cavity.
牙医在日常临床实践中可能会遇到色素沉着病变。在大多数情况下，这些病变无症状且本质上是良性的；然而，色素沉着病变很少会是恶性肿瘤的迹象。我们报告一例上颌牙龈恶性黑色素瘤病例，以强调对口腔中出现异常局灶性色素沉着病变的患者进行活检和定期随访的重要性。
