Heterotopic ossification in upper midline abdominal scars.

Area of Science:

• Surgical pathology
• Abdominal surgery complications

Background:

• Heterotopic ossification is a rare condition characterized by bone formation in non-osseous tissues.
• It has been observed to occur in abdominal incision scars following surgical procedures.

Purpose of the Study:

• To report and characterize cases of heterotopic ossification in upper midline abdominal incision scars.
• To discuss the clinical presentation, management, and differential diagnosis of this rare complication.

Main Methods:

• Case series reporting on seven patients with heterotopic ossification of upper midline abdominal incision scars.
• Review of clinical data, surgical findings, and outcomes following excision in six patients.

Main Results:

• Seven male patients in their fifties developed heterotopic ossification in upper midline abdominal incision scars.
• The calcification, resembling a "rib", was located between the peritoneum and fascia, primarily attached to the fascia.
• Excision was performed in six patients, with recommendations for wide excision in symptomatic cases to avoid recurrence.

Conclusions:

• Heterotopic ossification is a potential, albeit rare, complication of upper midline abdominal surgery.
• Differential diagnosis should include other wound complications and intra-abdominal malignancies.
• Surgical management should be reserved for symptomatic cases and performed with wide margins to prevent recurrence.
