Oral malignant melanoma: a case report
The present case has been reported in the Journal of Indian Academy of Oral Medicine and Radiology.

A 55-year-old female patient presented with the chief complaint of a painless swelling in the anterior maxillary region which had begun 3 months ago. There was no history of trauma, systemic illness, or being associated with bleeding or pain. Intraoral examination revealed a nontender mass on the labial gingiva of the maxillary anterior of approximately 3 × 3 cm in size.

The mass was pedunculated, had a smooth surface, and well-defined margins. The color of the overlying mucosa was dark blue to black in some areas. Similar melanosis was evident on the palatal gingiva of maxillary anterior and buccal gingiva up to the region of maxillary second premolars on either side Clinical photograph showing a pedunculated dark blue to black mass of about 3 × 3cms on the labial gingiva of the maxillary anteriors and melanosis on buccal gingiva up to the region of maxillary second premolars on either side].

An incisional biopsy was done under local anesthesia, which showed sheets of polygonal cells with hyperchromatic nuclei with prominent nucleoli with mast cells showing brown-black melanin pigment. Areas of necrosis, hemorrhage, inflammatory cells infiltrate, and nuclear debris were also seen, giving the impression of malignant melanoma.

Patient was subjected to orthopantomography (OPG) and advanced imaging modalities such as computed tomography (CT), which showed no evident changes in the underlying bone. Clinical, radiographic, and ultrasonographic examination revealed no distant metastasis. Surgery was performed and 1-year follow-up did not show any recurrence.
