Tumours and tumorous lesions of head and neck account for 10% of all oncological pathologies. Branhyogenic cancer is found in 4.5% of patients with lateral cysts in the neck. The article highlights the results of research the clinical case of branhyogenic cancer, provide its clinical and morphological analysis. The aim of our work was to study the clinical case of bronchial cancer, providing clinical and pathomorphological analysis. Examination and treatment was conducted in accordance with the clinical protocol using the diagnostic criteria necessary for management of patients diagnosed with tumours and tumorous lesions in a particular clinical case. We applied ultrasound examination of the locus, angiography of head and neck vessels with tomohexol and with 3D reconstruction, histological examination of surgical specimens (macroscopy and microscopy). On the basis of clinical investigaton, ultrasound examination, angiography clinical diagnosis was formulated - lateral cyst on the left side of the neck. A radical surgical removal of the mass was conducted. Histopathological conclusion: there is a proliferation of cystic transitional cell epithelium with the locus of invasive squamous cell carcinoma in the cystic wall that suggests malignant transformation of bronchogenic cyst. Final diagnosis: branhyogenic cancer. Thorough examination and analysis of a clinical case demonstrates that the development of branhyogenic cancer, is histo-genetically associated with lateral cysts in the neck. Complexity of diagnosing and high percentage of malignancy induces to more early discovery and removal of lateral cysts in the neck.
Keywords: branhyogenic cancer; lateral cysts in the neck.
