Localized tracheobronchial amyloidosis, type AA, and its differentiation from the systemic form of amyloidosis in clinical practice

67-year-old patient with chronic obstructive pulmonary disease and chronic pansinusitis suffered from attacks of dyspnea, cough and common cold repeatedly. The chest X-ray was without clear pathology. Because of repeated difficulties, a bronchoscopic examination was made and a diagnosis of amyloidosis was made twice (bronchial biopsy, excision). The patient in our case suffered from a tracheobronchial form of amyloidosis (type AA most probably) together with chronic pansinusitis.
