Heterotopic ossification of the abdominal wall

Abstract EN

Heterotopic ossification is a rare and benign condition which occurs when bone develops in tissues that do not normally ossify.

We report a 53-year-old man who underwent laparotomy for recurrent pyloric obstruction.

A segment of abnormal hard tissue was found in the abdominal wall and so was excised.

Histopathology revealed metaplastic bone deposition.

Heterotopic ossification may occur at various sites and is a recognized but infrequent sequela of abdominal surgery.

This case highlights clinical, aetiological and histopathological features of this rare finding.
