Case series of neck accessory tragus

Area of Science:

• Dermatology
• Otolaryngology
• Medical Genetics

Background:

• Accessory tragus, a congenital auricular anomaly, can manifest in various locations.
• Cervical auricles are a specific type of accessory auricular anomaly, often presenting as masses on the neck.
• Reporting new cases contributes to understanding the prevalence and characteristics of these rare conditions.

Observation:

• Three pediatric cases of neck accessory tragus were documented in China, representing the largest reported series.
• Clinical presentation included skin-colored masses above the clavicle and gradually increasing neck masses.
• Histopathological examination revealed the presence of cartilage beneath the subcutaneous tissue in all three cases.

Findings:

• All three cases were definitively diagnosed as cervical auricles based on clinical and histopathological findings.
• The presence of cartilage is a key diagnostic feature of cervical auricles.
• This series highlights the occurrence of this anomaly in pediatric patients.

Implications:

• Increased awareness among dermatologists and otolaryngologists regarding cervical auricles is crucial for timely diagnosis.
• Early identification and management of accessory auricular anomalies can potentially prevent complications.
• Further research into the embryological origins and genetic factors of cervical auricles is warranted.
