Gongylonema pulchrum is a zoonotic parasite rarely found in humans. To date, there have been no reports on the carcinogenic properties of G. pulchrum, and there are few reports overall on the relationship between esophageal cancer and parasites. This report describes the first case of esophageal gongylonemiasis coexisting with early esophageal cancer. The patient had no high-risk factors for esophageal cancer, such as smoking, flushing after drinking, or tumor history. We speculate the existence of unknown links between esophageal cancer and parasitic infection in this patient. We report the first case of a human presenting both esophageal G. pulchrum infection and esophageal squamous cell carcinoma with the hope that it may provide evidence for a new hypothesis of tumorigenesis.

合并早期食道癌和弓形虫感染：1例报告

红线虫是一种很少在人类中发现的人畜共患寄生虫。迄今为止，还没有关于 G. pulchrum 致癌特性的报道，关于食道癌与寄生虫之间关系的整体报道也很少。本报告描述了首例早期食管癌并存的食管弓形虫病。患者无吸烟、酒后潮红、肿瘤病史等食管癌高危因素。我们推测该患者的食道癌与寄生虫感染之间存在未知的联系。我们报告了第一例同时存在食道 G. pulchrum 感染和食道鳞状细胞癌的人类病例，希望它可以为新的肿瘤发生假说提供证据。
