Ischaemic necrosis of subcutaneous colonic neoesophagus: an unusual complication of presternal hypertrophic scar.

Hypertrophic scars and keloids not only pose aesthetic problems but also cause functional and anatomical dysfunction by leading to contractures and sometimes by compression of underneath structures. A 76-year-old man presented with progressive dysphagia of two months duration. Examination showed the unusual complication of a presternal hypertrophic scar, causing ischaemic necrosis of a subcutaneously-transposed colon, used for oesophageal reconstruction in a patient with inoperable carcinoma of the oesophagus. Such a complication of hypertrophic scar has never been reported in the literature.
