Tracheobronchial Amyloidosis

Bronchopulmonary Amyloidosis


  • A diagnosis of TBA presenting as MLS was made. To the best of our knowledge, this is the first detailed report of MLS as a presentation of TBA in the English literature.[ncbi.nlm.nih.gov]
  • Patients with this condition most commonly present with postobstructive pneumonia, wheezing, and occasionally hemoptysis.[ncbi.nlm.nih.gov]
  • We present a case of TBA in a 20-year-old man that was treated successfully with rigid bronchoscopy and stenting. The patient presented with progressive dyspnea despite having had a tracheostomy fashioned at another institution.[ncbi.nlm.nih.gov]
  • A review of the available literature is presented.[ncbi.nlm.nih.gov]
  • The subdivision of tracheobronchial amyloidosis into submucosal plaques and tumour-like masses is questioned since there appears to be no difference in their clinical presentation and pathological appearance.[ncbi.nlm.nih.gov]
  • Several bronchoscopic patterns have been suggested: nodular, pseudotumor, polypoidal and sub-mucosal, 7 which together with endobronchial ultrasound (EBUS) (to discard mediastinal involvement) results in a full assessment of the disease by the bronchoscopist[archbronconeumol.org]

  • A 32-year-old, never-smoker man presented with episodic dyspnoea and wheezing along with cough and mucoid sputum. The chest radiograph was suggestive of a middle lobe syndrome (MLS).[ncbi.nlm.nih.gov]
  • Progressive dyspnea, cough and sputum were the most common symptoms. The percentage of patients undergoing computed tomography (CT) scan has increased over the years.[ncbi.nlm.nih.gov]
  • Of those 11 patients reporting cough, 5 reported sputum production. Four patients had experienced hemoptysis. Only two of the six patients complaining of hoarseness had documented laryngeal lesions.[journals.lww.com]
  • Sputum culture, sputum smear, serum carcinoembryonic antigen, anti-nuclear antibody, extractable nuclear antigen, lambda light chain, kappa light chain, hepatitis B and C viruses, HIV and Treponema pallidum tests were all normal.[omicsonline.org]
Decreased Breath Sounds
  • Physical examination showed decreased breath sounds in the right lung on auscultation. Chest computed tomography scan displayed multiple nodules with varied size in main bronchia around bilateral hilus of the lung.[ncbi.nlm.nih.gov]
Laryngeal Disease
  • Amyloidosis of the stomach was noted in one of our patients 10 years after the initial presentation of laryngeal disease.[nature.com]
Foreign Body Sensation
  • One year previously, the hoarseness had become aggravated and was accompanied by foreign body sensation; however, the patient still did not devote much attention to the condition and underwent regular treatment.[omicsonline.org]
Mild Cognitive Impairment
  • cognitive impairment (n 236), or had AD-type dementia (n 115).[medworm.com]


  • Our case highlights presentation and workup of this disease. Methods. The index patient's workup included clinical exam, CT of the neck and chest, direct laryngoscopy, bronchoscopy, and biopsy.[ashdin.com]
  • Additional workup revealed a diffuse hypogammaglobulinemia, negative ANA, and elevated urine protein with sharp gamma spike (kappa light chain).[ucdenver.edu]
  • The gold standard for diagnosis is flexible bronchoscopy; however, because patients present with nonspecific symptoms ranging from cough to complete airway obstruction, imaging is often obtained as part of the initial workup. 18 The CT appearance of papillomatosis[appliedradiology.com]
  • The other patients had a negative systemic workup, which included physical examination, laboratory tests, radiologic studies, and biopsies (bone marrow, rectal, or lip).[nature.com]

  • It may cause airway obstruction, atelectasis and recurrent bronchopulmonary infections.[eurekaselect.com]
  • The most recent CT scan of the chest obtained in November 2002 revealed a continued improvement in the thickening of the right mainstem bronchus and near-complete resolution of right lower lobe atelectasis (Fig 4).[sildenafilakaviagra.com]

  • Chest X-ray, atelectasis in the left upper lobe. Because of the bleeding the patient underwent rigid bronchoscopy with endobronchial ultrasound (EBUS).[jpp.krakow.pl]
Amyloid Plaque
  • Amyloid plaques may also deposit in the airway submucosa, causing airway narrowing; the condition referred as "tracheobronchial amyloidosis" (TBA).[ncbi.nlm.nih.gov]


  • Data were collected including symptoms, method of diagnosis, treatments, result of treatments, and side effects. RESULTS: All patients received 20 Gy of radiation in 10 fractions.[ncbi.nlm.nih.gov]
  • Though there is no universally accepted treatment for the localized form, this patient was successfully treated with three sessions of bronchoscopic resection and adjuvant steroids.[ncbi.nlm.nih.gov]
  • Bronchoscopy has important value in the diagnosis, severity assessment, treatment, efficacy evaluation, and prognosis of TBA.[ncbi.nlm.nih.gov]
  • There is no consensus on the optimal treatment.[ncbi.nlm.nih.gov]
  • A systematic review was performed on 64 cases of primary TBA in China and progress in the diagnosis and treatment of this disease is discussed.[ncbi.nlm.nih.gov]


  • Bronchoscopy has important value in the diagnosis, severity assessment, treatment, efficacy evaluation, and prognosis of TBA.[ncbi.nlm.nih.gov]
  • The prognosis is thought to be worse with proximal or severe mid airways disease (as opposed to more distal pulmonary amyloidosis).[radiopaedia.org]
  • Key words: classification – incidence – prognosis of amyloidosis – clinical symptoms of pulmonary and systemic amyloidosis – differential diagnostics of various types of amyloidosis in clinical practice Notice The full wording of this article is available[vnitrnilekarstvi.eu]
  • Patients with systemic disease often have a much poorer prognosis.[ashdin.com]
  • In the absence of an effective drug therapy, local management of this disease with endoscopic techniques for bronchial repermeabilization is able to provide clinical improvement and expand the treatment options and prognosis in this disease.[archbronconeumol.org]


  • Etiology The etiology of tracheobronchial amyloidosis is unknown.[radiologykey.com]
  • So, for patients with chronic cough of unknown etiology, bronchoscopy should be performed to obtain biopsy samples for the definitive diagnosis.[ncbi.nlm.nih.gov]
  • Abstract Amyloidosis is a spectrum of diseases characterized by abnormal extracellular accumulation of proteinaceous material; its precise etiology still remains unclear.[ncbi.nlm.nih.gov]
  • The etiology of this disease may incorporate genetic polymorphisms, mutations, and local environmental changes, which contribute to altered protein folding, leading to increased beta-sheet conformations, and tissue deposition [ 2 ].[ashdin.com]
  • Discussion Amyloidosis is a rare disease of unknown etiology characterized by abnormal deposition of fibrillar proteins that typically exhibit apple-green birefringence under polarized light after Congo red staining.[archbronconeumol.org]
