Congenital anterior neck masses comprise a rare group of lesions typically diagnosed in childhood. Most commonly, lesions are anomalies of the thyroglossal duct, namely the thyroglossal duct cyst, along with ectopic thyroid tissue. Although usually suspected based on clinical examination, imaging can confirm the diagnosis, assess the extent, and evaluate for associated complications. Read More

Objectives: Congenital midline cervical cleft (CMCC) is a very uncommon congenital anomaly of the midline anterior neck, and although it has very pathognomonic features (including nipple-like protuberance), it could be mistaken for other congenital neck lesions, such as thyroglossal duct cyst and branchial apparatus anomalies. Thus, it represents a challenging diagnosis. In this 21-patient series, we discuss the clinical features of CMCC, its pathophysiology characteristics, and its modalities management. Read More

High-risk human papillomavirus (HPV) DNA has been reported to be present in branchial cleft cysts, but further information is required to clarify the role of HPV infection in branchial cleft cysts. The presence of HPV, the viral load and the physical statuses in samples from six patients with branchial cleft cysts were investigated using the polymerase chain reaction (PCR), quantitative PCR, hybridization (ISH) using HPV DNA probes and p16 immunohistochemical analysis. High-risk type HPV-16 DNA was identified in four of the six branchial cleft cysts analyzed. Read More

Superficial palpable masses of the head and neck are common in the pediatric population, with the vast majority of the lesions ultimately proven to be benign. Duplex ultrasonography (US) has emerged as the first-line imaging modality for the evaluation of superficial pediatric masses. Without utilizing radiation, iodinated contrast material, or sedation and/or anesthesia, US provides a means for quick and cost-effective acquisition of information, including the location, size, shape, internal content, and vascularity of the mass.

Preoperative discrimination of solitary cervical branchial cleft cysts from cystic lymph node metastasis often is challenging. Surgical excision of the cystic formation and consecutive histopathological examination of tissue specimens are the only means resulting in the correct diagnosis. However, in case of malignancies surgery on the lateral neck prior to the definitive treatment is considered to negatively influence the patients' outcome. Read More

Background: Distinguishing branchial cleft cysts (BCCs) from cystic metastases of a human papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma (OPSCC) is challenging. Fine needle aspirates (FNAs) from cystic metastasis may be non-representative, while reactive squamous cells from BCC can be atypic. Based on cytology and with the support of HPV DNA positivity many centers treat cystic metastasis oncological and thus patients are spared neck dissection. Read More

Background: Even though branchial cleft cysts are currently accepted as a congenital anomaly, there is often a long delay until clinical presentation; branchial cleft cysts classically appear in the second to fourth decade of life. Our observation of their occurrence in three pregnant women encouraged us to contemplate a possible hormonal influence.

Methods: Immunohistological analysis was performed for the evaluation of the estrogen receptor alpha (ER) in paraffin-embedded tissue specimens of 16 patients with a diagnosis of branchial cleft cyst, with three of them being pregnant. Read More

Aim: Solitary cystic masses of the lateral neck in an adult patient can pose a diagnostic dilemma. Malignancy must be ruled out since metastases arising from H&N cancers may mimic the presentation of benign cystic masses. Only a small number of studies have investigated the diagnostic management and malignancy rate of clinically benign solitary cervical cystic lesions. Read More

Background: A cervical cystic mass is associated with a number of pathologies that present with similar symptoms. These conditions are difficult to differentiate using fine-needle aspiration (FNA), ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI). Another dilemma in the differential diagnosis of cervical cystic masses is due to the controversies associated with the existence of branchiogenic carcinoma (BC). Read More

The majority of cystic squamous cell carcinomas (SCCs) of the neck have been shown to be metastatic tumors from tonsillar SCCs associated with high-risk human papillomavirus (HR HPV). Recent studies have demonstrated cytokeratin (CK)7 involvement in the development of HPV positive SCC, but no report has been issued on its simultaneous expression in primary tonsillar and metastatic tumor with cystic change. We present a case of HPV positive tonsillar SCC of a 42-year-old male that initially manifested as a cystic neck mass expressing CK7, CK19, and p16 in primary and metastatic tumors. Read More

There is a group of lesions in the head and neck region derived from branchial arches and related structures which, when inflamed, are characterized by the formation of cysts lined by squamous or glandular epithelium and surrounded by a heavy inflammatory infiltrate rich in germinal centers. In the thyroid, the main source of various structures which may cause diagnostic dilemma is the ultimobranchial body. To investigate the spectrum of such thyroid lesions, the consultation files were reviewed for thyroid samples containing pathological structures regarded to arise from the ultimobranchial body.

Thyroglossal duct cysts followed by branchial cleft anomalies are the most common congenital neck masses encountered in practice, second branchial cleft cysts and sinuses are the most common type (LaRiviere and Waldhausen in Surg Clin North Am 92(3):583-597, 2012). Although both abnormalities are common individually, but rarely seen associated in same patient as described in our case. Congenitalcervical anomalies are important to consider in the differential of head and neck masses in children and adults. Read More
