[Pre-auricular angiomyxoma in a child]

Area of Science:

• Oral and Maxillofacial Surgery
• Pathology
• Dermatology

Background:

• Myxomas are uncommon benign tumors typically affecting the jawbone in adolescents and adults.
• This report details a rare presentation of a myxoma in the preauricular region.

Observation:

• A cystic, slow-growing tumor was identified in the right preauricular area.
• Surgical exploration revealed a well-encapsulated, lobular tumor with small cystic cavities.
• Histological examination showed myxomatous tissue with a prominent capillary network, resembling angiomyxoma.

Findings:

• The definitive diagnosis of the preauricular tumor was established through histological analysis.
• Histological and immunohistochemical evaluation is crucial for differentiating myxomas from other benign mixed tumors like neurinomas, lipomas, and histiocytomas.

Implications:

• Complete surgical excision is the recommended treatment for this type of benign tumor.
• This case highlights the importance of considering myxomas in the differential diagnosis of preauricular masses.
• Long-term follow-up confirmed the patient's complete recovery and absence of symptoms after surgical intervention.
