1) The differential diagnoses for the contents are as follows: metastatic disease, lymphoma, adenitis, obstructed submandibular duct, salivary gland tumors, abscess, Ludwig's angina, thyroglossal duct cyst, hemangioma, lymphangioma, dermoid/epidermoid, diving ranula (complex), second branchial cleft cyst
(more common in children) (Figure 16).
Of these, Rathke's pouch, Thornwaldt's, adenoid retention cysts are in the midline but branchial cleft cyst
is on the lateral wall of nasopharynx.
Branchial cleft cyst
can be inherited as an autosomal dominant trait (Bums, Dunn, Brady, Starr, & Blosser, 2009).
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.
Prior to referral, an ultrasound scan was carried out and revealed a 5 x 2 cm multiloculated (septated) cystic swelling, with internal septae, related to the right sternocleidomastoid with an initial impression of branchial cleft cyst
with internal haemorrhage.
The patient underwent excisional biopsy of the right neck mass, with a clinical diagnosis of branchial cleft cyst
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.
One case had branchial cleft cyst
and CT showed a cystic lesion with good delineation of the extent of the lesion.
A barium swallow esophagogram revealed a fistulous tract from the piriform sinus to a right fourth branchial cleft cyst
(figure 1, B).
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).
