Cervical chondrocutaneous branchial remnants are rare and badly known lesions, located in the lower third of the lateral neck. They are similar in appearance to preauricular tags. Histologically, the lesion per definition presents as a choristoma. Treatment involves complete surgical removal in order to make an exact histopathological diagnosis. The authors report two cases, review the literature and discuss embryologic and diagnostic aspects.

| Introduction|| |
Cervical chondrocutaneous branchial remnants (CCBR) are uncommon and not well-known congenital lesions. There are few descriptions in the literature concerning pure chondrocutaneous rests in the lower neck region and even fewer descriptions concerning bilateral chondrocutaneous rests. In 1997, Atlan et al. described their findings in 20 retrospective evaluated cases of cervical skin tags and suggested the term "chondrocutaneous branchial remnants" in order to adopt a clear widely acceptable name for these malformations.
Treatment of these lesions is complete surgical removal as promptly as possible.
We report two cases of congenital bilateral and unilateral chondrocutaneous branchial remnants of the neck and discuss embryologic and diagnostic aspects.
| Case Reports|| |
A 3-year-old boy admitted to the clinic with bilateral, painless, pedunculated masses in the lower neck anterior to the sternocleidomastoid. Each mass measured about 12 mm. No signs of inflammation or infection were noted upon palpation. The mother stated that these masses were noticed directly after birth and have not grown since then. The mother denied any family history of neck masses. The physical examination of patient revealed an otherwise healthy and well-developed child. The excision of both lesions was performed under general anesthesia. These lesions appeared to be solid cartilaginous masses covered by normal-appearing skin. During the operation no sign of fistulization or communication to underlying structures was seen. The histological examination confirmed bilateral ectopic cartilage remnants. No recurrence was noted during the child's follow-up.
A 9-year-old girl presented with a right pedunculated tumor in the lower third of the neck, anterior to the sternocleidomastoid [Figure 1]. The tumor measured about 1.5 cm. No other swellings were present. The lesion had a firm, but elastic consistency and was mobile in relation to its underlying structures. The excision of the lesion was performed under general anesthesia. The histological examination confirmed the ectopic cartilage remnants [Figure 2]. No recurrence was noted during the child's follow-up.

| Discussion|| |
During the embryonic phase, the branchial arches are initially positioned in a ventral position and migrate along the sternocleidomastoid muscle to a more cranial position.  Cells that are left behind during this process, can give rise to the formation of CCBR. , This explains why they are frequently attached to the sternocleidomastoid muscle as was the case for our patients.
Atlan et al. in the literature, , consider that the possible origin of CCBR may be divided into two groups. One states that these lesions are derivatives of auricular tissue as the other group considers that these lesions originate from branchial tissue (lower arches).
The inspection of the type of cartilage found in the remnants can give an idea on the origin: Elastic cartilage would suggest an auricular (first or second branchial arch) origin or perhaps a possible derivate of the lower neck (fourth through six branchial arches), hyaline cartilage on the other hand would suggest a cervical source (second or third branchial arches). ,
These malformations are characterized by predominance among males, scarcity of bilateral lesions and the presence of a cartilage core and a high incidence of associated anomalies. Their clinical features are the following: Present at birth and located in the middle or lower third of the neck with a significant prevalence anterior to the sternocleidomastoid muscle. The overlying skin is similar to the surrounding neck skin and the lesion is painless, lacking any inflammation or discharge. 
CCBR require, despite their clear clinical markings, a broad differential diagnosis.  This latter include thymic and thyroglossal duct cysts, branchial cleft cysts, hair follicle nevus, congenital midline hamartomas, fibroepithelial polyps, epidermoid cysts and squamous papillomas. Thymic cysts are lined by stratified squamous epithelium and fluid-filled. Thyroglossal duct cysts are located in the anterior neck and can sometimes contain thyroid follicles. Branchial cleft cysts are located in the lateral neck and are lined with upper respiratory epithelium; they have a shallow epidermal pore and contain seromucinous glands. Congenital midline hamartomas have a prominent skeletal muscle component and are found on the anterior mandibula. Epidermoid cysts, squamous papillomas and fibroepithelial polyps do not usually involve differential diagnostic difficulties. 
The surgical treatment of these remnants is a simple excision extending to the superficial neck musculature, which was done in our case and proved sufficient.
Although it is stated in the literature that branchial system malformations are commonly associated with other congenital defects, ,, no other malformations were found in our two cases.
| Conclusion|| |
Cervical chondrocutaneous branchial remnants (CCBR) are very rarely reported congenital entity. Here we reported two cases of congenital bilateral and unilateral chondrocutaneous branchial remnants of the neck and discussed the embryologic and diagnostic aspects too.
