Material and Method: Five cases of pediatric chondrocutaneous branchial remnants or accessory pinna were included. Te ratios of the longest dimensions of the external ear to that of the accessory tragus/chondrocutaneous branchial remnants were calculated. Results: Te 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: Te current literature and norms of terminology dictate that two diferent 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. Key Words: Cartilage, Choristoma, Head and neck neoplasms ÖZ Amaç: Bilateral servikal lezyon olarak ender sunulan kondrokutanöz brankial artıklar ya da aksesuar pinna spektrumunu irdelemek ve biyolojik davranışını tartışmak. Gereç ve Yöntem: Beş çocukluk çağı kondrokutanöz brankial artık ya da aksesuar pinna olgusu sunulmaktadır. Dış kulak ile aksesuar tragus/kondromatöz brankial artıkların en uzun boyutlarının oranları hesaplandı. Bulgular: Kondrokutanöz brankial artık ya da aksesuar pinnanın boyutu ve büyüme hızı, lezyonlar ile normal pinna arasındaki mesafe ile ters orantılıydı. Sonuç: Geniş literatür taraması ve terminolojik açıdan bakıldığında, temelde histolojik olarak aynı olan lezyonların farklı terminoloji ile anılmasından kaçınılmalıdır. Kondrokutanöz brankial artıklar, ak- sesuar pinna/tragus ve kondroid/kartilajinöz koristomlar patogenez açısından benzer lezyonlar olduklarından koristomlar olarak isim- lendirilmelidir.

Medical College, HIMACHAL PRADESH, INDIA INTRODUCTION Te presence of heterotopic cartilage under the skin in the head and neck region constitutes a cartilaginous choristoma. Teoretically the choristomas can be of diferent types such as heterotopic presence of thyroid gland, bone, glial tissue and salivary gland, etc. Te common theme shared by diferent choristomas is that these are very slow growing and benign. Te excision is generally done either for cosmetic purposes or to rule out any possibility of malignancy (1). External cartilaginous choristomas in the head and neck region are now named chondrocutaneous branchial remnants or accessory pinna with the implication that all these lesions are remnants of one of the branchial arches. However, the similar heterotopic cartilage in the mouth, tonsillar region or pharynx is named cartilaginous choristoma even though the biological behavior and histopathological features of all these lesions regardless of the site are identical to the heterotopic presence of mature cartilage covered by overlying skin or mucosa (2). We present 5 cases of chondrocutaneous branchial remnants/ accessory pinna/ tragus or cartilaginous choristoma located in the neck and cheek.
