Core Tip
Core Tip: A 63-year-old male, with a long history of heavy smoking, was diagnosed with chronic myelomonocytic leukemia (CMML), with additional sex combs-like and enhancer of zeste homolog 2 gene mutations, as well as non-small cell lung cancer (squamous cell carcinoma). However, no such mutations were found in the lung cancer tissue. In CMML patients, pulmonary manifestations are non-specific, and the rare presence of malignant tumors in the lungs poses challenges in diagnosis. After receiving azacitidine, programmed cell death protein 1, and platinum-based chemotherapy drugs, the patient developed severe myelosuppression and eventually fatal leukocyte stasis and dyspnea. Therefore, during treatment and observation of CMML, medical practitioners should pay attention to the occurrence and evolution of solid tumors such as lung cancer, and be vigilant of the growth of multiple primary malignant tumors.
