Complete spontaneous regression of a metastatic melanoma of the mandible: a case report and follow-up recommendations.

Regression of metastatic melanoma is very rare and occurs in only 0.23% of cases. Metastasis to the oral cavity is particularly uncommon and accounts for only 1-3% of all oral malignancies. This report presents a case of spontaneous and complete regression of a metastatic melanoma in the mandibular ramus. The patient remains asymptomatic more than 2 years after diagnosis. The patient was followed up regularly. It is recommended that further surveillance imaging be performed in asymptomatic patients following discussion with the surgical and oncological teams. This type of surveillance, together with new systemic treatments, is advocated due to its potential to increase long-term survival even after relapse.
