Summary:	Oral mucosa melanoma (OMM) is a rare malignant neoplasm of aggressive character, and it accounts for fewer than 1% of malignant oral lesions. This paper presents a case of OMM manifesting as a large focal pigmentation on the hard palate. A 54-year-old male patient was referred by a general dentist for specific assessment of the detected lesion. During anamnesis, the patient reported smoking for twenty years and abstaining from the habit for twenty years. On oral examination, a focal black pigmentation with red areas was observed in the median region of the hard palate, extending from the canine to upper second molars region. The diagnostic hypothesis was OMM. Upon incisional biopsy, the tissue fragment revealed mucosa covered by stratified epithelial tissue and partially ulcerated, as well as the presence of neoplasia containing melanin pigments, compatible with OMM. After diagnostic confirmation, the patient was referred to the head and neck surgery service of the local cancer center, where 27 sessions of radiotherapy and 4 sessions of brachytherapy were performed. Systematic clinical examinations of the oral cavity for the detection of asymptomatic and isolated pigmentations are necessary, and it is important to improve dentists' knowledge of the nature of these lesions, since early diagnosis is essential to increase the chances of curing this aggressive malignancy.
