1/47. Possible branchiogenic carcinoma coinciding with metastatic papillary thyroid carcinoma.We report the discovery of a cystic lesion of flat lining epithelium with areas of squamous carcinoma, associated with metastatic cervical nodes of a papillary thyroid cancer, and discuss the diagnostic possibilities.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/47. Thyroid papillary carcinoma arising in ectopic thyroid tissue within a branchial cleft cyst.A case of papillary carcinoma arising in ectopic thyroid tissue within a branchial cleft cyst is described. A 46-year-old woman presented with a 2.0 x 2.0 cm mass in her left lateral neck. The excised mass showed a cystic lesion with a thyroid papillary carcinoma. Following a lateral cervical cystectomy, subsequent thyroid gland and lymph nodes dissections were performed. Pathological examination showed an adenomatous goiter and no primary carcinoma in the thyroid gland, as well as metastatic papillary carcinoma in the lymph nodes. Two cases of thyroid papillary carcinoma arising in ectopic thyroid tissue within a branchial cyst have been reported previously, but no lymph node metastases were recognized. The first case of papillary carcinoma arising in ectopic thyroid tissue within a branchial cleft cyst, and accompanied by lymph node metastasis is presented.- - - - - - - - - - ranking = 1.1111111111111keywords = carcinoma (Clic here for more details about this article) |
3/47. Solitary nodal metastases presenting as branchial cysts: a diagnostic pitfall.Two patients with metastatic squamous cell carcinoma are presented. Both were initially clinically diagnosed as branchial cysts. The importance of a full examination of the upper aerodigestive tract, and fine needle aspiration cytology is emphasised to avoid the possibility of excision as a branchial cyst, which could lead to tumour dissemination.- - - - - - - - - - ranking = 0.11111111111111keywords = carcinoma (Clic here for more details about this article) |
4/47. Radiological appearance of primary branchial cleft cyst carcinoma.The hypothesis that primary branchiogenic carcinoma originates from a branchial cleft cyst is controversial. Many reports regarding primary branchiogenic carcinoma failed to provide sufficient evidence to distinguish it from metastatic cervical lymph nodes arising from previously unrecognized primary tumours. The radiological appearance of malignant transformation from a branchial cleft cyst has not been reported previously in the English literature. A radiological study is presented that confirms the primary branchiogenic carcinoma. The management in suspected cases would be wide surgical excision of the tumour including ipsilateral radical neck dissection followed by radiation therapy.- - - - - - - - - - ranking = 0.77777777777778keywords = carcinoma (Clic here for more details about this article) |
5/47. Thyroid papillary carcinoma in lateral neck cyst: missed primary tumour or ectopic thyroid carcinoma within a branchial cyst?We report a case of thyroid papillary carcinoma lying within a lateral cervical cyst for which no occult primary tumour of the thyroid was identified. We explore the possible diagnoses and include a discussion of how ectopic thyroid tissue may come to lie within a branchial cyst.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
6/47. Fine-needle aspiration cytology of lymphangioma of the parotid gland in an adult.lymphangioma or cystic hygroma is an uncommon benign congenital tumor of lymphatics that is seen in children and, rarely, adults. lymphangioma primarily involving the parotid gland is an extremely uncommon occurrence in adults. We report on the cytologic findings of a parotid lymphangioma in a 34-yr-old man which showed 13 cc of yellow fluid with red blood cells, lymphocytes, and rare fragments of benign-appearing salivary gland epithelium. The differential diagnosis of cystic parotid gland lesions in adults may include Warthin's tumor, lymphoma, benign lymphoepithelial lesions, branchial cleft cysts, chronic sialadenitis, cystic low-grade mucoepidermoid carcinoma, and cystic pleomorphic adenoma. In this case, the fine-needle aspiration findings along with the magnetic resonance imaging (MRI) findings of a multiloculated cystic mass in the parotid gland allowed the diagnosis of lymphangioma.- - - - - - - - - - ranking = 0.11111111111111keywords = carcinoma (Clic here for more details about this article) |
7/47. Differential diagnosis of a lateral cervical cyst and solitary cystic lymph node metastasis of occult thyroid papillary carcinoma.We present a case of solitary cystic lymph node metastasis from an occult thyroid papillary carcinoma mimicking a lateral cervical cyst, and a case of thyroid papillary carcinoma with a true lateral cervical cyst. Based on a comparison of the radiographical findings of the two cases, differential diagnosis between cystic lymph node metastasis of papillary carcinoma and branchial cyst is discussed.- - - - - - - - - - ranking = 0.77777777777778keywords = carcinoma (Clic here for more details about this article) |
8/47. Intrapericardial bronchogenic cysts.A rare case of large intrapericardial bronchogenic cyst with superior vena caval obstruction is reported. The cyst was successfully removed and the superior vena cava, which was narrowed by pressure fibrosis and thrombosis, was reconstructed satisfactorily and has maintained patency. In another case a large cyst of the same type without vena caval obstruction was successfully treated surgically. The features of these 2 cases are compared with those of 20 reported cases. The angiographic data in these cases appear to be sufficiently characteristic to suggest the nature of the lesion and the clinical finding of pericarditis early in the course of the disease may also suggest the diagnosis.- - - - - - - - - - ranking = 0.47638641113674keywords = bronchogenic (Clic here for more details about this article) |
9/47. Cystic metastasis versus branchial cleft carcinoma: a diagnostic challenge.OBJECTIVES: There is controversy regarding the existence of branchial cleft carcinomas. The objectives are to familiarize the clinician with the presentation and treatment of cystic metastases from head and neck primary sites and differentiate these from primary branchial cleft cyst carcinomas. STUDY DESIGN: Retrospective case study and literature review. methods: Published reports of branchial cleft carcinomas were reviewed in conjunction with a unique case presenting at the University of texas Medical Branch (Galveston, TX). RESULTS: Most cases of branchial cleft carcinomas are probably cystic metastases from head and neck primary sites. Cutaneous involvement with primary branchial cleft carcinomas is rare but may occur in recurrent lesions. CONCLUSIONS: The diagnosis of a primary branchial cleft cyst carcinoma requires the fulfillment of strict criteria. Cystic metastases from head and neck primaries can mimic branchial cleft carcinomas histologically. Correct diagnosis is important so that appropriate surgical and radiotherapeutic treatment can be delivered.- - - - - - - - - - ranking = 1.2222222222222keywords = carcinoma (Clic here for more details about this article) |
10/47. carcinoma in situ in a lateral cervical cyst.BACKGROUND: The development of an invasive squamous cell carcinoma within a lateral cervical cyst as a result of malignant transformation of the epithelium is considered a rare circumstance. The existence of this entity is a source of controversy in light of the differential diagnosis, which includes a cervical metastasis from an unknown primary carcinoma (CUP-syndrome). Apart from site, histologic findings, and follow-up, the principal diagnostic criterion for lateral cervical cyst carcinoma is the histomorphologic demonstration of transition of the benign epithelium into invasive squamous cell carcinoma. Although numerous case reports of this entity exist, carcinoma in situ in a lateral cervical cyst has been reported in only five cases thus far. METHOD: In this context, we present the case of a 44-year-old patient with a 7-month history of cervical swelling. RESULTS: After diagnostic extirpation of the tumor, histologic findings were consistent with a lateral branchial cyst with high-grade dysplasia and carcinoma in situ of the squamous epithelial lining. CONCLUSION: This case of a premalignant lesion within a lateral branchial cyst (ie, carcinoma in situ) supplies the "missing link" and adds credibility to the concept of primary branchiogenic carcinoma.- - - - - - - - - - ranking = 0.88888888888889keywords = carcinoma (Clic here for more details about this article) |
