The majority of branchiogenic carcinomas are cystic metastases originating in the tonsils, and not true carcinomas arising in a branchial cleft cyst. Isolated cystic neck lesions necessitate a thorough search for a primary tumor, as with other occult primaries presenting with cervical metastases. As the existence of primary branchiogenic carcinoma is controversial, Martin and colleagues and then Khafif and coworkers established a series of widely accepted criteria to recognize this type of carcinoma. We report a case of a large cervical mass, consistent with a branchiogenic carcinoma of the second branchial arch. The patient underwent excision of the neck mass through a radical neck dissection. The cyst wall was found to have squamous cell carcinoma arising from the benign epithelium. Follow-up at 7 years revealed no evidence of recurrence. All diagnostic criteria for a true branchiogenic carcinoma were met in this case. The absence of adjuvant irradiation is a further confirmation that the mass is not a cystic node metastasis but a carcinoma arised from within a branchial cleft cyst.展开更多

They represent approximately 2% of all laterocervical tumors and 6% to 85% of anomalies of the second branchial cleft. This anomaly of the second branchial cleft is a frequent reason for consultation in the pediatric population but is relatively rare in adults. We report the cases of two patients aged 23 and 34 years with no particular pathological history. They were presenting a laterocervical swelling, one right and the other left, painless, evolving for two years for the first and for 10 years for the second, gradually increasing in volume without any other associated signs the diagnosis of which after radiological exploration (ultrasound and CT scan) was that of an amygdaloid cyst. A cervicotomy with anatomopathological examination of the surgical specimen confirmed the diagnosis of the amygdaloid cyst. The objective is to analyze the anatomo-clinical and therapeutic particularities of this pathology and to compare it with data from the literature.展开更多

Second branchial arch cysts and abscesses occur mainly in older children or young adults while fistulae are discovered in young children. We report a case of complete second branchial arch fistula of Bailey III type with adult complaints of painful swelling and local reddishness followed by spontaneous discharge and disappearance of complaints. Diagnosis was based on ultrasound and confirmed by CT scan, with the classic “beak sign” visible on both exams. Three cases were encountered in the family, with no otologic or kidney symptoms, which is quite different from the classical branchiootorenal syndrome which associates severe inner ear and kidney congenital anomalies.展开更多

Case presentation: A 40-year-old male was referred to our department for a lateral neck mass assessment. Physical examination revealed a solitary palpable, painless, moveable neck mass. Assessment included complete nasal, pharynx and larynx endoscopy, neck computed tomography, and fine needle aspiration biopsy. Treatment was surgical excision of the neck mass. Histopathology confirmed a branchial cleft cyst with papillary thyroid carcinoma growth at a site. A neck and thyroid ultrasound showed presence of thyroid gland nodules (one of which with micro calcifications). Thyroid fine needle aspiration biopsy performed, was high suspicious for malignancy (BETHESDA V). Patient underwent total thyroidectomy and histopathology revealed papillary thyroid carcinoma. Conclusion: Although rarely, it is possible to face an unexpected malignancy within a clinically benign neck lesion. A thorough diagnostic work-up enables early identification of aforementioned potential malignancy. A diagnostic dilemma that arises in such cases is between primary or metastatic disease and a thyroid carcinoma arising from ectopic thyroid tissue.展开更多

Those who support its existence adhere to rigid criteria to validate its existence. Those that deny it, purport that the entity is simply metastatic disease masquerading as a branchial cleft primary. One aspect of agreement between the two opposing views is that a separate head and neck primary disqualifies the diagnosis of branchiogenic carcinoma. We report a case in which branchiogenic carcinoma was diagnosed in the presence of an additional base of tongue primary squamous cell carcinoma based on morphologic dissimilarity and evidence of origination from the basal layer of the branchial cleft epithelium. In doing so, we attempt to make the case that unequivocal histologic evidence of branchial cleft origin is the defining feature of branchiogenic carcinoma and, as with many other carcinomas, should be the diagnostic criterion of choice in issuing the diagnosis. A brief pertinent literature review is presented.展开更多
