Abstract
Introduction
Heterotopic ossification of large joints is a commonly seen and described entity in Burn survivors. We have observed a rather uncommon phenomenon in a series of 4 Burn survivors who presented to our Burn center for scar treatment and open wounds many years after their injuries. A chronic, small, splinter-like subcutaneous irritation led to open wounds and infections in their burn scars. A similar condition is known as dystrophic calcinosis cutis in the dermatologic literature, but caused by calcium metabolism changes in otherwise healthy skin.
Methods
The demographics and history of illness was documented in all 4 patients. A literature review was performed. The calcified bone-like irritant was removed surgically in all patients, sometimes in more than one location. Pathologic evaluation was performed on the removed specimen. Strategies leading to healing of the wounds were evaluated.
Results
Four publications were found addressing this phenomenon in Burn scars, all case reports. All of our patients had undergone curettage of the lesions by a dermatologist in the past without resolution. All lesions were excised surgically and proved to extend subcutaneously far more extensively than the visible skin lesion. X rays proved not helpful in preoperative assessment of the extent. All wounds healed after the irritant was removed.
Conclusions
All lesions appeared to have formed along tendon or fascia remnants underneath the burn scars, exerting pressure on the overlying epithelium which eventually led to breakdown and necrosis. This finding prompted the term “heterotopic cutaneous ossification”. Chronic tension and inflammation were assumed in the etiology, rather than calcium metabolism abnormalities or systemic connective tissue disease, which were not present in these patients. Research is needed to establish the prevalence, cause, and prevention of this condition in Burn survivors.
