Abstract Introduction/Objective Malignant melanoma arises from neural crest-derived cells called melanocytes. These melanocytes migrate to several sites, including the skin and the mucous membranes. Oral melanoma (OM) cases account for <1% of all melanoma cases and <2% of all oral malignancies. Primary malignant melanoma of the jaw is an even rarer entity. Most OM cases arise in the palate and the maxillary alveolar gingivae. Other sites, such as mandibular gingiva and buccal mucosa, are rarely involved. The etiopathogenesis remains unclear, with stimulation of melanoblasts being one of the proposed hypotheses. The incidence is highest in the fifth and sixth decades of life and occurs more commonly in males than females. Clinically, it remains an asymptomatic pigmented growth until it reaches advanced stages. Diagnosis in advanced stages leads to OM having an overall survival (OS) rate of just 15.4% at 10 years with an abysmal prognosis. These neoplasms are highly invasive and metastasize quickly. Of mutations, KIT (14.6%), BRAF (7%) and NRAS (5.6%) were the most frequently encountered in OM cases. Methods/Case Report We searched for “oral melanoma” in our healthcare system for the last 10 years- from 2013 to 2022. 4 cases were selected for this case series, and pertinent information was pulled from CoPath and Epic software. The cases were then analyzed, and the results were reported. Results (if a Case Study enter NA) In our case series, we found the mean age to be 78.5 years, with 75% (3 of 4) of the patients being male and the rest 25% (1 of 4) female. Three cases were diagnosed with melanoma or malignant melanoma, while the 4th case had atypical melanocytic proliferation favoring malignant melanoma as the diagnosis. Regarding the tumour site, 1 case arose in the right anterior maxilla, 2 cases involved the mandible (left mandible and right anterior mandibular vestibule, respectively), and 1 case was present in the buccal mucosa. Microscopic findings and immunohistochemistry results concurred with the diagnoses. Conclusion Herein, we present 3 cases (out of the 4) from rarer sites, such as the mandible and oral mucosa, as opposed to the typical sites- the palate and the maxilla. Discussing rarer cases helps physicians to keep these in the differential while examining similar tumors. Additionally, having rarer cases adds to the literature and focuses attention on entities that require more study and research. Since these neoplasms are highly invasive and metastasize quickly, they necessitate an early diagnosis for effective management.
