Abstract

The simultaneous occurrence of achalasia and esophageal diverticula is rare. Here, we report the case of a 68-year-old man with multiple esophageal diverticula associated with achalasia who was later diagnosed with early esophageal cancer. He initially presented with dysphagia and dyspepsia, and injection of botulinum toxin to the lower esophageal sphincter relieved his symptoms. Five years later, however, the patient presented with worsening of symptoms, and esophagogastroduodenoscopy (EGD) was performed. The endoscopic findings showed multifocal lugol-voiding lesions identified as moderate dysplasia. We decided to use photodynamic therapy to treat the multifocal dysplastic lesions. At follow-up EGD 2 months after photodynamic therapy, more lugol-voiding lesions representing a squamous cell carcinoma in situ were found. The patient ultimately underwent surgery for the treatment of recurrent esophageal multifocal neoplasia. After a follow-up period of 3 years, the patient showed a good outcome without symptoms. To manage premalignant lesions such as achalasia with esophageal diverticula, clinicians should be cautious, but have an aggressive approach regarding endoscopic surveillance.
