Objective: To present and critically examine the spectrum of chondrocutaneous branchial remnants or accessory pinna, including rare case of bilateral cervical lesions, and to explain the basis of the biological behavior.
Material And Method: Five cases of pediatric chondrocutaneous branchial remnants or accessory pinna were included. The ratios of the longest dimensions of the external ear to that of the accessory tragus/chondrocutaneous branchial remnants were calculated.
Results: The size and rate of growth of chondrocutaneous branchial remnants or accessory pinna were found to be inversely proportional to the distance between the lesions and the normal pinna.
Conclusion: The current literature and norms of terminology dictate that two different terminologies for lesions that are essentially histologically identical should be avoided. Chondrocutaneous branchial remnants, accessory pinna/tragus and chondroid/ cartilaginous choristomas are identical lesions with similar pathogeneses and should be referred to as choristomas.

Cervical chondrocutaneous branchial remnants (CCBR) are rare causes of neck masses in young children. It is commonly associated with genitourinary and cardiac anomalies. We report a case of CCBR in a two-year-old male child who presented with a unilateral painless pedunculated neck mass.

Cervical chondrocutaneous branchial remnant is a rare congenital developmental anomaly typically located on the lateral neck. Histologically, it has the appearance of an accessory tragus demonstrating a central cartilaginous core with surrounding fibrosis located in the subcutaneous tissue. In order to address the clinical and therapeutic aspects of cervical chondrocutaneous branchial remnants in children, a 6-year-old boy who presents with bilateral hard cervical masses at the lower region of the neck is presented.

Article Synopsis
- Kürsteiner canals (KC) are embryological remnants linked to parathyroid and thymic development, with ongoing research aimed at understanding their role in various parathyroid lesions and cysts.
- A study evaluated 62 cystic and 22 non-cystic parathyroid lesions over a 12-year period, identifying distinct KC phenotypes in relation to the presence of parathyroid hormone (PTH).
- The findings reveal that KC commonly appear in parathyroids, particularly in non-PTH cysts, and suggest that these manifestations may originate from KC, while PTH-positive cysts are associated with different characteristics.

Epidermoid and dermoid cysts are benign, usually slow-growing lesions classified as ectodermal inclusion cysts. These cysts form when epithelial remnants become trapped during the closure of the first and second branchial arch; however, a few cases are related to trauma or are iatrogenic. Diagnosis is made based on the cyst development history and imaging such as ultrasound.
