Clinicopathological characteristics of cervical chondrocutaneous branchial remnant: a single-institutional experience.

Cervical chondrocutaneous branchial remnant (CCBR) is an uncommon developmental anomaly typically seen on the lateral neck. We recently experienced four cases of CCBR and initiated a comprehensive review of previously published cases. During a 10-year period, four (0.4%) of the 1,096 patients who underwent excision of branchial cleft anomalies were diagnosed as having CCBR at our institution. Patient age ranged from 2-6 years and patients presented with asymptomatic cutaneous masses present since birth measuring approximately 1 cm on the lateral neck. Three patients had congenital thyroid hemiagenesis, subependymal cyst, and tongue tie, respectively. We identified 76 previously published cases of CCBR. The median age of these patients was 18 months. CCBR developed more often in males (48/80; 60.0%). Most of the masses were located on the left (34/80; 42.5%) or right (18/80; 22.5%) lateral neck, whereas 23 (28.75%) involved bilateral lesions. Lesion size ranged from 0.3-3.5 cm. Grossly, the overlying skin of the masses was similar to the surrounding skin of the neck. Histologically, the lesions were covered by keratinizing squamous epithelium and had skin appendages and cartilage. Thirty-nine (48.75%) and 12 (15.0%) patients were found to have elastic and hyaline cartilage, respectively. Twenty-eight patients had single (13/28; 46.4%) or multiple (15/28; 53.6%) congenital anomalies. Forty-four different types of anomalies were reported. The most frequent anomalies were problems with cardiovascular and auditory systems. Our observations suggest that CCBR is a visible marker for more serious associated congenital anomalies. We recommend that clinicians and pediatricians further evaluate patients with CCBR through complete physical examination, abdominal and cardiac ultrasound, karyotyping, and biochemical marker analysis.

A Case of Accessory Tragus on the Posterior Neck / 대한피부과학회지

Cervical accessory tragus is a rare congenital malformation presenting at birth as a firm nodule on the neck along the anterior edge of the sternocleidomastoid muscle. It has also been reported under different names, such as elastic cartilage choristoma of the neck, Meckel's cartilaginous remnant, cervical tab, cervical auricle, and wattle. Histologically, cervical accessory tragus is composed of numerous hair follicles, and a prominent connective tissue framework in the subcutaneous fat and central core of cartilage. We report a case of an 8-year-old female who presented with a solitary flesh colored papule on the posterior neck that was histopathologically diagnosed as cervical accessory tragus.
