Other causes included metastatic (11 patients), nonspecific inflammation (14 patients), lymphoma (4 patients), infectious branchial cleft
cysts (2 patients), or other infectious cervical cysts (6 patients).
Based on these findings, a diagnosis of bilateral second branchial cleft
fistulae was made.
Some of the primary PPS masses include minor salivary gland tumors arising from ectopic salivary gland tissue rests, atypical type II first branchial cleft
anomaly, and lipomas.
Differential diagnosis of TC should include choanal polyp, angiofibroma, nasopharynx cancer, mucosal and adenoid retention cysts, chordoma, meningomyeloceles and meningoceles, adenoid retention cysts, branchial cleft
cysts, and Rathke's pouch cysts.
Differential diagnosis of Thornwaldt's cyst is branchial cleft
cyst, Rathke's pouch cyst, adenoid retention cyst, meningocoele, sphenoid sinus mucocoele, JNA and possibly nasopharyngeal carcinoma.
Cyst--Caused by the incomplete closure of the sinus tract during embryonic 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.
Diagnosis in adults is considered to present a greater challenge than in children and initial misdiagnosis, frequently as branchial cleft
cysts as in the case reported here, is common.
The patient underwent excisional biopsy of the right neck mass, with a clinical diagnosis of branchial cleft
anomalies are some of the most common types of congenital neck masses.
Examples of benign neoplasms include TGDC, dermoid cyst branchial cleft
cyst and cervical adenitis Congenital lesions present from birth to shortly after birth and account for 55 percent of benign lesions.
