Abstract
INTRODUCTION AND IMPORTANCE: Mucosal melanoma of the oral cavity, a rare and aggressive malignant tumor, most commonly located in the hard palate or maxillary gingiva/ridge, underscores the urgent need for early diagnosis. These tumors are typically asymptomatic, highlighting the crucial role of medical professionals in improving patient outcomes significantly through early detection. CASE PRESENTATION: We present a case of oral melanoma in a 62-year-old male patient with a history of diabetes mellitus and significant tobacco use. The patient presented with a painful mass on the left hard palate. Computed tomography (CT) imaging of the maxilla revealed a significant bone defect in the left maxillary canine-premolar region. An incisional biopsy of the mass confirmed the diagnosis of invasive melanoma. The patient subsequently underwent a left maxillectomy and was referred to an oncologist for further treatment. DISCUSSION: Oral melanoma, while uncommon, is a disease of grave concern due to its aggressive and invasive behavior. This demands immediate attention and action from medical professionals. Its asymptomatic nature frequently results in late-stage detection, significantly impacting treatment outcomes and prognosis. CONCLUSION: Clinicians should be vigilant about intraoral pigmented or atypical nonpigmented lesions. Lesions showing color changes or sudden enlargement should be biopsied and evaluated histopathologically. This vigilance is crucial for early diagnosis and treatment, which can significantly impact patient outcomes.
