Cat scratch esophagus

Area of Science:

• Gastroenterology
• Endoscopy
• Pathology

Background:

• Cat scratch esophagus is an uncommon entity, with the first reported case in the colon in 2007.
• Only two esophageal cases have been documented, with this being the first identified using capsule endoscopy.

Observation:

• The condition presents as linear, erythematous, shiny, and superficial mucosal breaks.
• These lesions are not typically associated with significant hemorrhage.
• Diagnosis is primarily morphological.

Findings:

• The etiology remains unknown, but barotrauma from insufflation is a suspected pathogenic mechanism.
• Associations with conditions affecting esophageal elasticity and prior NSAID use have been noted.

Implications:

• Capsule endoscopy may play a role in diagnosing rare esophageal conditions like cat scratch esophagus.
• Further research is needed to elucidate the exact etiology and optimize management strategies.
• Understanding this entity contributes to the broader knowledge of esophageal mucosal abnormalities.
