Cervical Chondrocutaneous Branchial Remnant Presenting as a Congenital Lateral Neck Papule in a 3-Year-Old Boy.

A congenital inferolateral-neck papule with a visible or palpable firm subcutaneous cord should prompt consideration of a cartilaginous remnant. This cord-like extension may mimic a branchial sinus tract, but clinicopathological correlation is required to distinguish cervical chondrocutaneous branchial remnant from an epithelial-lined sinus/fistula.
