Abstract:
The Ehlers-Danlos' syndrome (EDS) constitutes a group of connective tissue disorders that are clinically and genetically heterogeneous. Mutations in the TNXB gene have been recognized as pathogenic causing classical-like EDS due to tenascin-X deficiency. Here, we have reported a unique case of compound heterozygous mutation in TNXB gene leading to esophageal stricture and scarred skin in a 7-year-old boy who presented to us with impacted foreign body in esophagus. The child was also having tendency to atrophic skin scarring secondary to trivial trauma.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
