Primary Malignant Melanoma of the Lung (PMML); A Case Report.

Primary pulmonary malignant melanoma (also called primary malignant melanoma of the lung, or PMML) is an exceedingly rare non-epithelial neoplasm, accounting for 0.01% of all primary lung cancers. We report a case of a 63--year--old male with no comorbidities who was found to have a large right lung upper lobe mass and was diagnosed with metastatic primary malignant melanoma of the lung. The outcome for primary pulmonary malignant melanoma is grim, with 5-year survival less than 20%, but many patients have rapid progression and a short life span, even with intervention.
