Cystic nodal metastasis of thyroid papillary carcinoma mimicking branchial cleft
cyst: Two case reports.
Work, "Newer concepts of first branchial cleft
defects," Laryngoscope, vol.
Based on the MRI signal and clinical presentation, we considered that our case should be classified as a first branchial cleft
fistula with cysts.
In this report, we described the diagnosis and successful management of 2 cases of second branchial cysts in adult Amazon parrots, one likely originating from a remnant of the second branchial cleft
and the other from a remnant of the second branchial pouch.
The purpose of this overview is to summarize the current concept of carcinomas arising in branchial cleft
cysts (so-called, branchiogenic carcinoma), indicating that most, if not all, represent cystic metastases from oropharyngeal squamous cell carcinoma primaries.
Third/fourth branchial cleft
anomalies are rare and may present as an infectious swelling low in the floor of the neck laterally or in the anterior neck adjacent to the thyroid gland.
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.6,7
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.
As first branchial cleft
anomalies are another possible differential diagnosis, it is recommended to look carefully for a sinus opening within the external ear canal or around the ear .
The differential diagnosis of laryngopyocele includes laryngeal cyst, fluid-filled laryngocele, branchial cleft
cyst and less likely paraganglioma, schwannoma, and thyroglossal duct cysts.
(43) For this reason, first branchial cleft
cysts, which represent the second-most common branchial cleft
anomaly, can arise anywhere from the external auditory canal through the parotid gland to the submandibular triangle.
