“… 1 ENEC is usually located in the mid to distal esophagus, which is thought to be due to the predominance of endocrine cells within the distal cardiac glands and Merkel cells in the middle esophagus. 11 Numerous case reports demonstrate that most neuroendocrine carcinomas develop in the distal esophagus and are associated with columnar lining, as seen in Barrett's esophagus. 12 These findings support the conclusion that an iatrogenic cause contributed to the development of NEC in our patient's upper esophagus.…”

Esophageal neuroendocrine carcinoma is very rare and highly aggressive. An 85-year-old man with a history of esophageal squamous cell carcinoma in remission presented 4 years after definitive chemoradiation with new-onset dysphagia. Endoscopy with biopsy revealed high-grade malignancy consistent with neuroendocrine carcinoma. Treatment options were limited to chemotherapy because of his metastatic disease, and he unfortunately died 14 months after diagnosis. The occurrence of esophageal neuroendocrine carcinoma in a site of prior squamous cell carcinoma is very uncommon, and this likely represents a case of radiation-induced malignancy. Therefore, when undergoing radiotherapy, patients and providers should discuss the possibility of this life-threatening complication.

Background Neuroendocrine carcinomas are extremely rare in the esophagus as they represent less than 0.04% of all neuroendocrine tumors. To date, only 14 cases of poorly differentiated, high-grade esophageal NEC have been described in the literature. The majority of these patients presented with typical dysphagia symptoms. Due to its rarity, no standardized guidelines have been proposed to treat esophageal neuroendocrine carcinoma, although general recommendations suggest surgery with adjuvant chemoradiotherapy as the treatment of choice. Case presentation A 67-year-old previously healthy White male presented with a year-long intermittent nonspecific retrosternal discomfort, with the absence of any other symptoms. Esophagogastroduodenoscopy revealed an ulcerative mass in his lower esophagus, with concern of malignancy. Endoscopic ultrasound-guided biopsy revealed poorly differentiated neuroendocrine carcinoma of the esophagus with metastasis to a diaphragmatic lymph node. He was treated with neoadjuvant chemoradiation followed by surgery, and he has been in remission for over 5 years. Conclusion Here, we review the literature and report a unique case of a patient with a vague presentation of esophageal neuroendocrine carcinoma as he enters his sixth year of survival following neoadjuvant chemoradiotherapy.
