Uncommon Endoscopic Findings in a Tylosis Patient: A Case Report

Area of Science:

• Gastroenterology
• Oncology
• Genetics

Background:

• Palmoplantar tylosis is a rare genetic disorder characterized by hyperkeratosis of the palms and soles.
• It is strongly associated with an elevated risk of esophageal squamous cell carcinoma (OSCC).
• The genetic basis involves the RHBDF2 gene, inherited in an autosomal dominant pattern.

Observation:

• Limited data exists on the endoscopic appearance of the esophageal mucosa in tylosis patients prior to cancer development.
• This study documents characteristic endoscopic findings in individuals with tylosis who do not have cancer.
• Surveillance endoscopy, including annual esophagogastroscopy with biopsies, is recommended for family members.

Findings:

• Characteristic endoscopic mucosal changes were observed in patients with palmoplantar tylosis without cancer.
• Prospective documentation of these changes is crucial for refining screening protocols.
• The study highlights the importance of early detection through regular endoscopic examinations.

Implications:

• Establishing a better screening protocol for esophageal squamous cell carcinoma in tylosis patients is essential.
• Supplemental interventions, such as carotenoids, may potentially delay disease progression or revert mucosal changes.
• Further research into endoscopic findings and preventative strategies can improve patient outcomes.
