A case of auricular chondroma

Area of Science:

• Orthopedic Surgery
• Dermatopathology
• Surgical Oncology

Background:

• Extraskeletal chondroma is a rare, benign soft tissue tumor.
• Typically presents as a solitary nodule, often in the extremities.
• Auricular involvement is exceptionally uncommon.

Observation:

• A rare case of extraskeletal chondroma originating in the auricle is presented.
• The tumor manifested as a slowly growing, solitary subcutaneous nodule.
• Diagnosis was confirmed histopathologically.

Findings:

• The auricular chondroma was successfully treated with wedge excision.
• Reconstruction of the defect was achieved using a Burow's triangle technique.
• Literature review highlights the rarity of auricular extraskeletal chondroma.

Implications:

• This case expands the known anatomical distribution of extraskeletal chondroma.
• Demonstrates the efficacy of standard surgical techniques for rare auricular tumors.
• Highlights the importance of considering rare diagnoses in auricular masses.
