Second branchial cleft cyst
Discussion:
- well-defined cystic lesion at the left angle of mandible/submandibular space (between the submandibular gland, sternocleidomastoid muscle and carotid sheath). It is likely a 2nd branchial cleft cyst. Possible differential diagnosis includes cystic hygroma, necrotic malignant lymphadenopathy (of squamous cell carcinoma head & neck or papillary thyroid carcinoma), thymic cyst and cystic vagal schwannoma.
the lesion was surgically excised and a histopathological diagnosis of 2nd branchial cleft cyst was made.
