The etiology and formation pattern of heterotopic ossifications (HO) are still unknown. They occur in soft tissues in which bone does not normally form, near one or more proximal joints. In this article, the authors report a peculiar case of a 31-year-old patient affected by scapulo-humeral ankylosis that occurred about 6 months after a coma, in which two unusual concomitant conditions were observed: HO formation in the scapulo-humeral region and the development of keloids during wound repair. The scapulo-humeral ankylosis was resolved surgically with the removal of the HO, which was then studied morphologically to understand its formation pattern. By light microscopy and transmission electron microscopy, it was observed that heterotopic bone displays the normal microscopic structure of primary bone, in which two types of bone tissue were recognized, i.e., woven-fibered bone, deeply located and produced first, and lamellar bone. This suggests that the pattern of HO formation retraces the ontogenetic steps that normally occur during intramembranous ossification. The authors also discuss the peculiar concomitance of HO formation and keloid development, speculating that, although they are different conditions localized in dissimilar regions, they might be hypothetically triggered by a common event, such as the release of factors likely issued during the coma status.
