The image shows respiratory bronchiolitis, characterized by the accumulation of pigmented (smoker's) macrophages within distal airspaces. Aspiration usually results in amorphous or birefringent particulates within distal airspaces. Answer C is associated with hypersensitivity pneumonia, while type I hypersensitivity reactions are associated with atopic asthma. Respiratory bronchiolitis is a marker of current or former smoker status and is usually of no clinical consequence with no. Definition: Follicular bronchiolitis refers to a pattern of numerous reactive lymphoid follicles in a peribronchial/peribronchiolar distribution. It may occur either alone or as a secondary finding in association with bronchiectasis, chronic bronchitis, asthma, and other conditions. (3) an idiopathic group The presence of lymphoid hyperplasia in diffuse panbronchiolitis raises the pathologic differential diagnosis of follicular bronchiolitis, which occurs in the setting of systemic connective tissue diseases, allergic conditions, and immunodeficient states. Follicular bronchiolitis may also demonstrate secondary pathology because of airway obstruction. However, it is characterized by more prominent (even confluent) and bronchocentric lymphoid follicles; these have well-defined. Conclusion: The cardinal CT feature of follicular bronchiolitis consists of small centrilobular nodules variably associated with peribronchial nodules and areas of ground-glass opacity Follicular bronchiolitis (FB) is a small airways disease reported in RA patients, which results from hyperplasia of bronchus-associated lymphoid tissue. We report the case of a 49-years-old Caucasian female, who presented with an erosive polyarthritis of hands and wrists at the age of 25, with positive anti-citrullinated protein antibodies and negative rheumatoid factor

Usually solitary cold nodule on radionuclide scan Follicular bronchiolitis (FB) is rare bronchiolar disorder characterized by the development of hyperplastic lymphoid follicles with germinal centers around the small airways 1. With the enlargement.. Background: Follicular bronchiolitis is a lymphoproliferative form of interstitial lung disease (ILD) defined by the presence of peribronchial lymphoid follicles. Follicular bronchiolitis has been associated with viral infection, autoimmune disease and immunodeficiency. The most common clinical manifestation is respiratory distress in infancy followed by a prolonged course with gradual improvement. We found no reports of systematic review of high-resolution computed tomography (HRCT.

Follicular bronchiolitis (FB) is a benign lymphoproliferative lung disease characterized by hyperplastic mucosa-associated lymphoid tissue present around the peribronchial spaces . Patients with FB are often associated with collagen vasculitis diseases, immunodeficiency state, hyperimmune state, and hereditary factors. Idiopathic FB is rare. Lymphocytic interstitial pneumonia (LIP) is also a benign lymphoproliferative lung disease characterized by severe lymphocytic infiltration. Follicular bronchiolitis (FB) is a nonneoplastic primary polyclonal B cell hyperplasia of the bronchus-associated lymphoid tissue (BALT) due to chronic exposure to antigens in those with underlying collagen vascular or immune deficiency diseases which usually manifested as small centrilobular ground glass nodules with lower lobe distribution Follicular hyperplasia - see lymph node pathology. +/-Colonies (clusters) of actinomycetes in the tonsillar crypts.

Histologically, all patients had lymphoid hyperplasia along the bronchioles; eight had peribronchiolar lymphocytic infiltration. CONCLUSION: The cardinal CT feature of follicular bronchiolitis consists of small centrilobular nodules variably associated with peribronchial nodules and areas of ground-glass opacity bronchiolitis, aspiration bronchiolitis, follicular bronchiolitis, hypersensitivity pneumonitis, and diffuse panbronchiolitis. Although constrictive bronchiolitis, also known as bronchiolitis oblit- erans and obliterative bronchiolitis, can occur in isolation, it is typically a pathologic pattern result-ing from other conditions (eg, an autoimmune process, an infection, or a manifestation of.

Three clinicopathologic groups were identified: 1) patients with collagen vascular diseases, especially rheumatoid arthritis and Sj{\o}gren's syndrome; 2.

Follicular bronchiolitis could be considered a manifestation of nodular lymphoid hyperplasia as an immune response against an antigen, with the consequent lymphocytic proliferation. Nevertheless, most patients do not develop follicular bronchiolitis after antigenic exposure; therefore, this stimulation would not be sufficient to explain the pathogenesis. Two stages can be defined in its. Microscopically, follicular bronchiolitis shows lymphoid follicle hyperplasia with well-formed germinal centers along the bronchovascular bundle with no or minimal lymphoid infiltration of interstitial tissue. The hyperplastic lymphoid follicles can obstruct the bronchioles, causing bronchiectasis and secondary infection. The etiology of follicular bronchiolitis is unknown. It has been speculated that the disease is a hypersensitive reaction to unknown antigens or related to bacterial. Most are subpleural but do not form pleural plaques. Histopathologic features.

Follicular lymphoma may also present in the thyroid gland, but its clinicopathologic features at this site are not well characterized, leading to difficulties in diagnosis and clinical management. We have addressed this problem by studying the clinical, morphologic, immunophenotypic, and genetic features of 22 such cases. All cases showed morphology characteristic of follicular lymphoma. Follicular bronchiolitis is usually seen in patients with connective tissue disease, immunodeficiency disorders, or chronic infections. Diffuse panbronchiolitis is an unusual form of bronchiolitis described mainly in the Asian population (particularly in the Japanese). Diffuse aspiration bronchiolitis is typically seen in middle-aged or older adults who have risk factors for aspiration, such. Respiratory Bronchiolitis Associated Interstitial Lung Disease.

When germinal centers are also present, the condition is termed follicular bronchiolitis (FB).2,3 IMAGING OF SMALL AIRWAYS DISEASE Small airways disease is difficult to detect by conven-tional radiographic imaging and physiologic testing until widespread involvement has occurred. In recent decades Lymphoid infiltrates in the lung leading to lymphoid interstitial pneumonia or follicular bronchitis/bronchiolitis without granuloma are equally challenging because they lead to cough, shortness of breath, alveolar damage, and ultimately, the need for oxygen therapy. Because of scarring and the predominance of T cells in the lung infiltrate (as shown in Figure 1), cyclosporine also has been.
