Objective  To investigate and analyze the clinical features of primary pulmonary malignant melanoma. Methods  The medical records, imaging examinations, pathological results, treatment and prognosis of four primary pulmonary malignant melanoma (PMML) patients were retrospectively collected. In combination with 96 cases reported in the literature, a total of 100 patients with PMML were analyzed. Results  Among the 100 PMML patients, there were 60 males (60.0%) and 40 females (40.0%), with an average age of 56.9±10.3 years. Common clinical symptoms were cough (60.0%), chest tightness or pain (18.0%), hemoptysis (16.0%), and dyspnea (11.0%). Distant metastasis was found in 30 cases (30.0%) at the time of consultation. The clinical stage of the first diagnosis and evaluation of the patients was stage Ⅰ in 7 cases (7.0%), stage Ⅱ in 24 cases (24.0%), stage Ⅲ in 13 cases (13.0%), stage Ⅳ in 39 cases (39.0%), and 17 cases (17.0%) did not mention a clear tumor stage. Thirty patients (30.0%) received comprehensive anti-tumor therapy, 53 patients (53.0%) received surgical resection, and 17 patients among them (17.0%) received postoperative adjuvant comprehensive therapy. The overall median survival time of PMML patients was 8.0 (2.0 - 14.4) months. The median survival time of stage Ⅳ PMML patients was 5.0 (3.1 - 6.9) months, which was significantly lower than 24.0 (6.0 - 32.0) months of stage Ⅱ patients (P<0.05) and 15.0 (0.6 - 29.4) months of stage Ⅲ patients (P<0.05). Further analysis showed that different treatment regimens had no significant effect on the median survival time of patients with stage Ⅳ PMML (P>0.05). Conclusions  PMML has a high degree of malignancy and no specific clinical symptoms. It is mainly diagnosed by pathology. Surgical resection, postoperative adjuvant chemoradiotherapy or immunotherapy are the main treatment methods, but its overall prognosis is poor.
