BACKGROUND
Small cell lung carcinoma (SCLC) is highly susceptible to metastasis in the early stages of the disease. However, the stomach is an uncommon site of metastasis in SCLC, and only a few cases of this type of metastasis have been reported. Therefore, SCLC gastric metastases have not been systematically characterized and are easily missed and misdiagnosed.
CASE SUMMARY
We report three cases of gastric metastasis from SCLC in this article. The first patient presented primarily with cough, hemoptysis, and epigastric fullness. The other two patients presented primarily with abdominal discomfort, epigastric distension, and pain. All patients underwent gastroscopy and imaging examinations. Meanwhile, the immunohistochemical results of the lesions in three patients were suggestive of small cell carcinoma. Finally, the three patients were diagnosed with gastric metastasis of SCLC through a comprehensive analysis. The three patients did not receive appropriate treatment and died within a short time.
CONCLUSION
Here, we focused on summarizing the characteristics of gastric metastasis of SCLC to enhance clinicians' understanding of this disease.
Core Tip: Due to the rarity of small cell lung carcinoma (SCLC) gastric metastasis, few cases have been reported internationally, and clinicians are not sufficiently aware of the clinical features of this group of diseases. In this article, we report three cases of SCLC gastric metastasis to summarize the characteristics of this type of disease and improve the understanding of the diagnosis and treatment of SCLC gastric metastasis.
