introduction:most metastatic lymph nodes from head and neck malignancy are solid. cystic nodes are found in 33% - 61% of carcinomas arise from waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. some cystic cervical metastases were initially presumed to be branchial cleft cyst. this case report aims to highlight the unusual presentation of cystic cervical metastasis sec...

We report an unusual sequence of clinico-pathological manifestations of myelodysplastic syndrome and thymic squamous cell carcinoma. A 77-year-old man with a two-month history of myelodysplastic syndrome was admitted with acute chest pain and shortness of breath. Radiological investigations revealed an anterior mediastinal mass, associated with mediastinal haemorrhage. The mass was excised via ...

Although thymic ectopy has long been recognized in humans, the functional activity or potential immunological significance of this thymic tissue is unknown. In this study, we describe murine thymic ectopy, cervical thymic tissue that possesses the same general organization as the thoracic thymus, that is able to support T cell differentiation, and that can export T cells to the periphery. Unexp...

The congenital thymic cysts are rare. They have a congenital origin and they are benign. The differential diagnosis of acquired cysts, cystic thymoma and thymic malignancies in cystic degeneration can be particularly difficult. Rarely, they assume clinical relevance for the appearance of symptoms of compression, more typical of malignant lesions, and the association with thymoma was reported in...

Cervical thymic masses are congenital lesions that result from aberrant thymic migration during embryogenesis. Although most of these masses are asymptomatic, they may cause debilitating symptoms secondary to encroachment on adjacent aerodigestive structures. Preoperative diagnosis of ectopic thymic tissue is rare; most cases are clinically misinterpreted as branchial cleft remnants or cystic h...
