A diverticulum is the medical or biological term for outpouching of a hollow structure in the body. It particularly occurs in the digestive system, but rarely occurs in the oral mucosa.
This report describes a rare case of diverticulum presenting in the buccal mucosa in a 44-year-old woman that was initially diagnosed in Stomatology Hospital, Wuhan University. We made our diagnosis under the guidance of imaging data, and the patient underwent surgical resection.
This report is the first confirmed case of buccal mucosal diverticulum. in addition, we elucidated that in general, idiopathic developmental abnormalities caused by succinate muscle defects are responsible for diverticulum development.
Core tip: Oral mucosal diverticulum is rare, and diverticulum of digestive tract has not been previously reported. Partial defects of the muscle layer around the diverticulum were also observed during the operation, and the diverticulum was located at the fragile edge of the anatomy of the muscle layer. After the operation, the patient’s food impaction symptoms were resolved, and have not relapsed.
