anomalies make up 30% of all pediatric neck masses, but complete second branchial cleft
anomalies are extremely rare.
38) The most commonly accepted theory of anomalous development is persistence of trapped cell rests from incompletely obliterated branchial apparatus, resulting in development of branchial cleft
cysts later in life.
Lesions may resemble a pyogenic granuloma, actinomycosis, a thyroglossal duct cyst, a branchial cleft
cyst, a furuncle, a squamous cell carcinoma and an epidermal cyst (1).
Based on topography and the histopathologic and immunohistochemical results, the masses were determined to be a second branchial cleft
cyst for the first case and a second branchial pouch cyst for the second case.
The patient underwent excisional biopsy of the right neck mass, with a clinical diagnosis of branchial cleft
cysts, sinuses, and fistulas are the most common congenital lateral neck lesions in children.
5) Differential diagnosis for unilateral lesions containing cysts includes sialolithiasis, first branchial cleft
cyst, HIV-associated BLEL, adenoid cystic carcinoma, and benign mixed tumor.
The differential diagnosis of cystic cervical masses includes thyroid cyst, thymic cyst, thyroglossal duct cyst, branchial cleft
cyst, bronchogenic cyst, lymphangioma and parathyroid cyst (PC) (1).
The 2 lesions that first come to mind in the differential diagnosis of a solitary cystic lesion in the neck are thyroglossal duct cyst and branchial cleft
We report a true case of primary branchial cleft
cysts (BCC) arise from incomplete obliteration of any branchial tract, resulting in either a cyst (75%) or sinus tract (25%).
1) It occurs as the result of a developmental anomaly of the first branchial arch, and it may be associated with other branchial cleft
