Abstract
BACKGROUND

Cronkhite-Canada syndrome (CCS) is a rare, non-genetic disorder characterized by multiple gastrointestinal polyps, and ectodermal lesions such as alopecia, fingernail atrophy, and skin mucosal pigmentation. Unfortunately, the pathogenesis of CCS is currently unknown.

CASE SUMMARY

Here, we describe the case of an elderly female with diarrhea, fatigue, and hair loss, who experienced abdominal pain for over half a year and was found to have multiple gastrointestinal polyps. She was diagnosed with CCS and was treated with albumin supplementation and prednisone, and her electrolyte imbalance was corrected. Following treatment, her symptoms significantly improved. To elucidate the role of potential genetic events in the pathogenesis of CCS, we performed exome sequencing using an extract of her colorectal adenoma.

CONCLUSION

Our data revealed multiple somatic mutations and copy number variations. Our findings provide a novel insight into the potential mechanisms of CCS etiology.

Core Tip: Cronkhite-Canada syndrome (CCS) is a rare, non-genetic disorder characterized by multiple gastrointestinal polyps, ectodermal lesions including alopecia, fingernail atrophy, and skin mucosal pigmentation. However, its pathogenesis is unclear. We performed exome sequencing in an elderly female patient and obtained somatic mutations in the hope that these data could provide a genetic perspective on the pathogenesis of CCS.
