Isolated osteochondroma near the mandibular angle

Area of Science:

• Oral and Maxillofacial Surgery
• Pathology
• Oncology

Background:

• Osteochondroma is a benign tumor originating from bone and cartilage.
• It typically develops near the ends of long bones.
• While rare in the oral cavity, it commonly affects the mandibular condyle and coronoid process.

Observation:

• This report details an exceptionally rare case of osteochondroma.
• The tumor was located in the soft tissue adjacent to the mandibular angle.
• Notably, the lesion lacked a direct bony pedicle.

Findings:

• The presented case is a non-pedunculated osteochondroma.
• It occurred in an atypical soft tissue location within the maxillofacial region.
• This finding challenges the typical presentation and location of oral osteochondromas.

Implications:

• This case expands the understanding of osteochondroma's varied presentations.
• It underscores the importance of considering soft tissue origins for benign tumors in the maxillofacial area.
• Further research into the etiology of extraskeletal osteochondromas may be warranted.
