a 63 years old woman with progressive mechanical dysphagia and weight loss: a case presentation

when considering a patient with dysphagia, an attempt should be made to determine whether the patient has difficulty only with solid boluses (suggestive of mechanical dysphagia) or with liquids and solids (suggestive of a motility dysphagia). lesions such as an oesophageal tumor and external pressure effect from a lung tumor or aberrant vessel can lead to mechanical dysphagia. endoscopy and / or a barium swallow are helpful in identifying the anatomical disarrangement. in this study a patient with progressive mechanical dysphagia is presented that finally diagnosed by as lung squamous cell carcinoma. there were no respiratory symptoms. diagnosis was made by a computerized tomography scan of the thorax, bronchoscopy and bronchial biopsy.
