A 72-year-old male with nausea and heartburn was found to have early pharyngeal squamous cell carcinoma, superficial and advanced esophageal squamous cell carcinoma and early esophageal adenocarcinoma by esophagogastroduodenoscopy. Computerized tomography demonstrated left cardiac lymph node swellings. We prioritized the treatment for esophageal squamous cell carcinoma, as this was the most advanced cancer among the triple primaries. The patient underwent neoadjuvant chemotherapy for esophageal squamous cell carcinoma followed by esophagectomy. Four months after esophagectomy, endoscopic submucosal dissection for pharyngeal squamous cell carcinoma was performed. This is a first report of pharyngeal squamous cell carcinoma, esophageal squamous cell carcinoma and esophageal adenocarcinoma occurring as triple primary cancers in a single patient. Smoking-induced tumor formation through DNA methylation is a common risk factor for patients with triple primary malignancies, being an example of epigenetic field cancerization induced by exposure to carcinogenic factors.
