A Case of Cervical Chondrocutaneous Branchial Remnant Comprised of Hyaline Cartilage

Abstract

Cervical chondrocutaneous branchial remnants (CCBRs) are rare, congenital, benign neck masses, and are derived from dislocated branchial apparatus components com

Cervical Chondrocutaneous Branchial Remnant: A Case Report and Review of the Literature

“…Therefore, CCBRs are likely best considered a second branchial remnant disorder, and the use of particular terms such as cervical auricle and accessory tragus should be avoided. 10…”

“…Therefore, CCBRs are likely best considered a second branchial remnant disorder, and the use of particular terms such as cervical auricle and accessory tragus should be avoided. 10 Recent studies have further expanded upon the various histologic features of CCBRs, with large nerves and clusters of Pacinian corpuscles documented at the periphery of these lesions. It has been hypothesized that the chondrocutaneous remnants attract sensory axons and neural crest cells that organize as Pacinian corpuscles in the vicinity of cartilage, as has been described in other cartilage or connective tissues.…”

Sonographic Findings of Cervical Chondrocutaneous Branchial Remnants—A Comparison With Dermal Lesions/Cysts and a Literature Review

“…These sonographic findings are useful for differentiating dermal cervical lesions. To date, case reports and other studies of CCBRs have been published mainly by otolaryngologists, dermatologists, pediatric surgeons, and plastic surgeons; [8][9][10][11][12]25,26,[29][30][31][32] sonographers and radiologists were not familiar with this disease. In the current study, we identified diagnostic characteristics that suggest the presence of a CCBR in ultrasound examinations.…”

“…appendages. 1,[3][4][5] CCBRs are usually located at the lower neck on the anterior or posterior border of the sternocleidomastoid muscle (SCM), 3,[6][7][8][9][10][11][12] which is also the site of other dermal lesions such as epidermoid cysts or branchial anomalies including lateral cervical cysts/sinuses or dermal sinuses of anterior chest lesions. [13][14][15][16][17] The clinical presentation of CCBRs varies and includes skin tag lesions or lesions with fistula connections to deeper structures.…”

“…Ultrasonography is widely used for pediatric patients because of its high resolution and bedside performance without irradiation and sedation. 23 Although some case reports have been published, 9,11,12,[24][25][26][27] to the best of our knowledge, clinical studies focusing on imaging findings of CCBRs in pediatric patients are lacking. Therefore, we aimed to demonstrate the usefulness of ultrasonography for the diagnosis and evaluation of CCBRs to differentiate them from other cervical dermal lesions in pediatric patients.…”
