Heterotopic ossification occurs when bone develops in tissues which usually don't undergo ossification. Heterotopic mesenteric ossification, also known as intra-abdominal myositis ossificans, is a rare and benign form of ossification, usually related with previous abdominal surgery or trauma.
We report two cases of heterotopic ossification both after multiple abdominal surgeries, with intraoperative findings of mesenteric and abdominal wall ossification. Histopathology revealed metaplastic bone deposition, without evidence of atypia or malignancy.
This rare entity shares clinical and pathological characteristics of myositis ossificans. It is important to consider the differential diagnosis with sarcomas. In the cases described, the patients were proposed for elective surgery and this pathology was as an incidental finding.
The simultaneous presence of mesenteric and abdominal wall ossification in both patients makes these cases even rarer.
异位骨化是指在通常不会发生骨化的组织中形成骨组织。异位肠系膜骨化，也称为腹腔内骨化性肌炎，是一种罕见的良性骨化形式，通常与既往腹部手术或创伤有关。
我们报告两例在多次腹部手术后发生异位骨化的病例，术中发现肠系膜和腹壁骨化。组织病理学显示化生骨沉积，无异型性或恶性证据。
这种罕见的疾病具有骨化性肌炎的临床和病理特征。重要的是要考虑与肉瘤进行鉴别诊断。在所描述的病例中，患者拟行择期手术，而这种病理情况是偶然发现的。
两名患者同时出现肠系膜和腹壁骨化，使这些病例更加罕见。
