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 cyst
12) On the basis of clinical appearance, the differential diagnosis includes pyogenic granuloma, actinomycosis, thyroglossal duct cyst, branchial cleft cyst
, furuncle, squamous cell carcinoma, and epidermal cyst.
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 cyst
We report a true case of primary branchial cleft cyst
The mass was diagnosed as a branchial cleft cyst
before complete excision was performed.
The differential diagnosis of a neck mass presenting in infancy includes a cystic hygroma, branchial cleft cyst
, thyroglossal duct cyst, hemangioma, vascular malformation, and an abscess.
The list includes various benign and malignant tumors, cholesteatoma, epidermal inclusion cyst, and first branchial cleft cyst
Ectopic thyroid tissue within a branchial cleft cyst
is rare, and a papillary carcinoma arising from this tissue is extremely rare.
