17%) in the suprasternal notch, and one (2.08%) in the retrosternal space. Histopathologically, 39 (81.25%) BCAs had a lymphoepithelial structure and nine (18.75%) BCAs had solitary epithelial cells. Inflammation and infection were observed in 24 (50%) and 12 (25%) cases, respectively. None of the hypothesized developmental theories fully explain the embryonic origin of BCA in our study sample. A possible explanation of BCA histogenesis is through the hybrid "branchial inclusion" theory. None of the hypothesized developmental theories
