A 51-year-old man with a 12.5-pack-year smoking history had symptoms suggestive of gastroesophageal reflux disease for 6 weeks. Over-the-counter antacids provided partial relief. For the past 2 weeks, he had worsening dyspepsia and a burning sensation in the epigastric region.
An endoscopic evaluation was performed. An image of the distal esophagus is shown.
What is the most likely diagnosis?
(Answer on next page.)
Correct answer: Glycogenic acanthosisGlycogenic acanthosis is usually benign. As shown here, it often consists of multiple papular esophageal lesions (Figure). This finding is not uncommon during endoscopic evaluation of the upper GI tract.1 The lesions are usually numerous and smaller than 2 cm, although they can be as large as 6 cm.2 Glycogenic acanthosis is rarely associated with Cowden syndrome, celiac disease, or reflux esophagitis. 3,4 Biopsy of the lesions must be performed to rule out other GI diseases.
This patient's biopsy results revealed benign epithelial hyperplasia-a frequent finding of glycogenic acanthosis. He was treated with a proton pump inhibitor for 2 weeks and by behavioral modification, which included counseling for smoking cessation. After 2 months, the patient's reflux symptoms resolved.
Less likely conditions in the differential include:
•Candida esophagitis. This infection is associated with white plaques, usually no more than 2 mm in diameter without ulceration. Biopsy of these lesions usually reveals the organisms.
•Herpes simplex virus esophagitis. This infection may have a “cobblestone” appearance similar to that of Candida esophagitis on a barium study. However, on endoscopic examination, the lesions are more discrete and resemble “punched-out” ulcers with yellow rims, also called volcano ulcers. Bullous formation is common, and ulcers may be exudative, mimicking Candida esophagitis. Biopsy is helpful in confirming the diagnosis.
•Crohn disease–related esophagitis. This condition may present with patchy ulcerations that involve the transmural region. Biopsy of these lesions often shows classic granuloma formation.
•Behet disease. This disease more commonly produces aphthous ulcers and rarely esophageal lesions. These ulcers may further cause erosions and stenosis of the esophagus. These findings are not consistent with glycogenic acanthosis.5
