A rare extraskeletal osseous lesion was found in the mesentery and omentum of a diabetic patient after surgery. This unique case of metaplastic bone formation highlights a potential complication following abdominal procedures.

Area of Science:

Gastroenterology
Surgical Pathology
Oncology

Background:

Extraskeletal osseous lesions are rare, with limited documented cases in abdominal soft tissues.
Understanding the histogenesis of bone formation in non-skeletal sites is crucial for differential diagnosis.

Observation:

A 63-year-old male with insulin-dependent diabetes presented with intractable intestinal obstruction post-aortic bifemoral bypass and laparotomies.
A unique extraskeletal pseudomalignant osseous lesion was identified in the mesentery and omentum.

Findings:

The lesion demonstrated new bone formation from connective tissue, suggesting a metaplastic process.
Histological features were compared to myositis ossificans and fasciitis ossificans.

Implications:

This case represents the first reported instance of such a lesion in the mesentery and omentum.
The findings suggest that abdominal surgery and associated stimuli may contribute to metaplastic bone formation in rare instances.
