Heterotopic ossification of the abdominal wall

Abstract

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

Heterotopic mesenteric and abdominal wall ossification – Two case reports in one institution

“…Although many causes have been proposed, the aetiology of this pathology is not consensual [1], [6].…”

Heterotopic mesenteric and omental ossification incidentally found in a patient with multiple abdominal surgical operations because of gunshot injury

“…[3,4] There is a striking male predominance (as high as 10:1) with an average age at diagnosis of 50 years. [3,6,10,13] Patients afflicted with heterotopic mesenteric and/or omental ossification commonly present with nonspecific abdominal symptoms, or, as in this case, it may be incidentally found during a laparotomy. [4,6,10] Bowel obstruction and intestinal perforation associated with bone-like lesions located inside the abdominal cavity were also presented in a few cases.…”

“…[1,3,4] Heterotopic bone-like formation is generally found not only in the mesentery but also in the mesoappendix, omentum, peritoneal surfaces, or laparotomy scars. [3,5,6] Due to its rarity, the data are limited to case studies, and the true incidence of this reactive process remains unclear. [6] In clinical settings, patients with mesenteric or omental ossification can be asymptomatic or may present with chronic abdominal pain, discomfort, or intestinal obstruction.…”

“…[3,5,6] Due to its rarity, the data are limited to case studies, and the true incidence of this reactive process remains unclear. [6] In clinical settings, patients with mesenteric or omental ossification can be asymptomatic or may present with chronic abdominal pain, discomfort, or intestinal obstruction. [7] We herein report a rare case of heterotopic mesenteric and omental ossification incidentally found in a 41-year-old male patient with multiple abdominal surgical operations because of a gunshot injury.…”

Recurrent hepatic mesenchymal hamartoma with osseous metaplasia

“…To our knowledge, this is the first case of recurrent hepatic MH with osseous metaplasia. The heterotropic bone formation is most likely a secondary reaction from previous procedure as it was located at the periphery of the lesion and bone is not known to be a MH component. Recognizing this phenomenon is important to distinguish it from other entities, particularly mesenchymal component of hepatoblastoma.…”
