Abstract

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.

小细胞肺癌的胃转移：三份病例报告和文献综述。

背景：小细胞肺癌（SCLC小细胞肺癌（SCLC）在疾病早期极易发生转移。然而，胃是 SCLC 不常见的转移部位，目前仅有少数此类转移病例的报道。因此，SCLC 胃转移尚未被系统地描述，很容易漏诊和误诊。病例摘要：本文报告了三例 SCLC 胃转移病例。第一例患者主要表现为咳嗽、咯血和上腹饱胀。另外两名患者主要表现为腹部不适、上腹胀痛。所有患者都接受了胃镜和造影检查。同时，三名患者病灶的免疫组化结果均提示为小细胞癌。最后，通过综合分析，三名患者被确诊为 SCLC 胃转移。结论：在此，我们重点总结了SCLC胃转移的特点，以提高临床医生对该疾病的认识。
