Malignancy arising in a 41-year-old colonic interposition graft.

The colon can be used for esophageal reconstruction after an esophagectomy. The development of a malignancy in the colonic interposition graft is rare, with less than 15 cases reported in the literature. We present a case of a 60-year-old male with high-grade dysplasia of the colonic interposition graft used for reconstruction of the esophagus, which developed 41 years after the esophageal reconstruction. The long-term complication of the development of a malignancy must be considered when using the colon for reconstruction especially when the esophageal reconstruction is performed for a benign cause.
