Rationale:
The synchronous occurrence of lung cancer in patients with gastric neoplasms is relatively uncommon, especially the cases of synchronous coexistence of small cell lung carcinoma and diffuse large B-cell lymphoma of the stomach.
Patient Concerns:
We encountered a case of synchronous primary small cell lung carcinoma and diffuse large B-cell lymphoma of the stomach. A 63-year-old patient with a 7.5 × 5.09 cm mass in the superior lobe of the right lung diagnosed with small cell lung cancer and synchronous diffuse large B-cell lymphoma of the stomach.
Diagnoses:
The diseases were diagnosed by the pathological biopsy and immunohistochemical methods.
Interventions:
As the patient received CHOP chemotherapy, pulmonary function deterioraed. Etoposide was added to the chemotherapy.
Outcomes:
However, after the first treatment, chest computed tomography showed that the mass in the superior lobe of the right lung had increased to 8.5 × 5.2 cm.
Lessons:
This report draws attention to the fact that the treatment of synchronous tumors is a challenge.
