A pharyngoesophageal diverticulum (PED) is a rare clinical entity. This paper reports on a 79-year-old male patient with PED and symptoms of dysphagia, regurgitation and chronic cough. The diverticulum was located on the dorsal side of the cervical esophagus, midline, inferior to the cricopharyngeal muscle. These findings were consistent with Laimer's diverticulum (LD), the rarest type of PED. This case proposes a surgical treatment of LD via an external transcervical approach.
