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.
