Rare Presentation of Benign Osteochondroma: A Case Report

Area of Science:

• Orthopedic Oncology
• Skeletal Dysplasias

Background:

• Osteochondromas are the most common benign bone tumors, representing developmental malformations originating from the periosteum.
• Typically affecting bones formed by enchondral ossification, they rarely arise from intramembranous ossification sites like the pelvis.

Observation:

• A rare case of osteochondroma presenting as a right inguinal swelling in a 24-year-old male is reported.
• The lesion was located near vital pelvic structures on the superior pubic ramus, with no visceral or vascular involvement.

Findings:

• Diagnosis of osteochondroma was confirmed via trocar biopsy.
• The pelvic origin and inguinal presentation are considered rare for this type of bone tumor.

Implications:

• Pelvic osteochondromas, though uncommon, should be included in the differential diagnosis for pelvic masses.
• Awareness of rare presentations is crucial for accurate diagnosis and management of benign bone tumors.
