Malignant cystic lesions of the lateral side of the neck are usually due to metastasis and are rarely primary carcinoma. The most common is metastatic cystic squamous cell carcinoma arising from a primary site at the Waldeyer's ring. However, they can arise from papillary carcinoma of thyroid, lung and mediastinum but very rarely from the abdominal and pelvic organs without regional lymph node involvement. Therefore, accurate diagnosis is very important for appropriate management. We report two cases of cystic squamous cell carcinoma of the lateral neck; cystic metastasis from an occult squamous cell carcinoma of the tongue and a primary branchiogenic carcinoma. We emphasize the importance of meticulous search for the primary malignant lesions in cases of cystic carcinoma of the neck.

A rare case of oropharyngeal branchial cyst in a fourteen-year-old boy is described. The cyst was located in the right lateral wall of the oropharynx. Histological examination revealed that the cyst was lined with a pseudostratified layer of the ciliated columnar epithelium and the lymphoid follicle. The position of the cyst and pathological feature were assumed to originate in the second branchial pouch.

PURPOSE: The purpose of this study was to evaluate the CT features of second branchial cleft cysts. MATERIALS AND METHODS: We retrospectively analyzed the computed tomographic images in nine cases of second branchial cleft cyst which was confirmed pathologically. Emphasis was on localization of the masses to fascial spaces as defined by the deep cervical fasica. RESULTS: In all nine cases, the lerions were located in the submandibular and carotid spaces. Among these cases, six(67%) had simultaneous involvement of the other contiguous spaces, such as anterior and posterior cervical spaces. All cases had round or oval, unilocular, cystic masses with partial or complete rim enhancement. In eight cases(89%), smooth and thin walls were observed. In one case, thick wall and septations were noted. No definite calcifications were noted in all cases. The internal contents of cystic masses showed relatively homogeneous appearance, and CT number ranged from 20 to 35.2 Hounsfield unit(HU)(mean, 28.4HU). CONCLUSION: CT diagnosis of second branchial cleft cyst would be easily obtained from recognition of frequent simultaneous involvement of the other contiguous spaces, along with a typical location and characteristic morphology.

Masses of the Parotid-Masseteric area can be caused by various different conditions, most commonly neoplasms of a benign nature. A rare cause for parotid tumors is the embryologic remnant of first branchial cleft cysts. A first branchial cleft cyst is an unusual clinical condition and is hard to be recognized. It is often misdiagnosed because its clinical feature is similar to what can be seen in other common diseases. So it may result in a diagnostic delay and insufficient and dangerous primary surgery. Definite surgical treatment of first branchial cleft cyst requires complete surgical excision, which usually necessitates identification and protection of the facial nerve and superficial parotidectomy. We report a case of first branchial cleft cyst that arose in parotid. We had a good aesthetic and functional result of surgical extirpation with sparing superficial parotid gland. There was no serious complication except temporary weakness of marginal mandibular branch of facial nerve.

The fourth branchial cleft cyst is rare and frequently unknown to clinicians. Misdiagnosis is common and definitive surgery is often made difficult by previous episodes of infection and incision. We have experienced a case of non-communicating dumbbell shaped fourth branchial cleft cyst. We performed complete excision of the entire epithelial tract after disarticulating the cricothyroid joint. There was no recurrence.

Cervical branchial cleft cysts are uncommon lesion that are developed from remnants of branchial apparatus in embryonal period. These cysts are found in infancy, childhood and adult by recurrent symptoms related to inflammation. It is difficult to find these cysts with antenatal ultrasonography and differential diagnosis from other cervical cysts is difficult too. We experienced a case of fetal cervical branchial cleft cyst that was found with antenatal ultrasonography and diagnosed with surgical biopsy, so we report our case with brief review of literatures.

The majority of cystic masses in the lateral neck are benign entities, and these entities include branchial cyst. Occult papillary thyroid carcinoma can occasionally present with regional lymph node metastasis. However, cystic metastasis from occult papillary thyroid carcinoma is a very rare condition. We present here a case of a cystic neck mass as the sole initial clinical manifestation of metastatic occult papillary thyroid carcionoma.

We report a very rare type of second branchial cleft cyst located at the oropharynx, and include a review of the literature. CT scans of the neck revealed a homogeneous non-enhancing low-density mass in the right posterolateral mucosal wall of the oropharynx. Only the peripheral capsule of the mass was enhanced. The cyst was resected perorally and proved to be a type-IV second branchial cleft cyst.
