Glycogenic acanthosis is a benign finding on oesophagography in elderly patients.
It most commonly occurs in patients >40 years of age and incidence and numbers of lesions increase by age. No gender predilection exists. Typically patients are asymptomatic.
It occurs from a combination of cellular hyperplasia and increased cellular glycogen in squamous epithelial cells lining the oesophagus. The oesophageal mucosa is otherwise normal. It is not thought to be associated with gastro-oesophageal reflux.
Severe forms are seen in patients with Cowden syndrome.
- multiple small nodules and plaques measuring 2-10 mm
- plaques are randomly distributed
- often in the upper to mid thoracic oesophagus
- the appearance can appear similar to other forms of oesophagitis like reflux oesophagitis which however occur more distally and candida oesophagitis which is more linear in configuration
