Case Report: A long-term survival case of primary malignant melanoma of the lung with meningeal metastasis

The diagnosis of pulmonary primary malignant melanoma requires a combination of many factors and is easy to be misdiagnosed. At present, there is no specific effective treatment plan, and such patients have a poor prognosis, are prone to distant metastasis, and their survival will be greatly shortened. The survival period of the patient in this case is longer than the average survival period of such patients, and the possibility of benefiting from immunotherapy is higher. Radiotherapy also reduces the discomfort symptoms of the patient to a certain extent, prolongs the survival of the patient, and provides certain ideas for clinical treatment.
