Bronchocentric granulomatosis is an uncommon entity which has no specific clinical, radiological and immunological features. It is usually diagnosed at morphological examination of biopsy or resected lung material. Aetiology of bronchocentric granulomatosis is unclear. A 49-year-old female patient, who was followed up with diagnosis rheumatoid arthritis in our outpatient clinic, presented with right lobe nodular lesion in chest radiography. Right thoracotomy and wedge resection was performed. Pathological examination revealed bronchocentric granulomatosis. Bronchocentric granulomatosis has been rarely reported in rheumatoid arthritis. This case might be a proof that bronchocentric granulomatosis may be one of the respiratory manifestations of rheumatoid arthritis.

Anti-tumor necrosis factor alpha (TNFα) therapy is widely used to treat various inflammatory conditions. Paradoxically, there are several case reports describing the development of bronchocentric granulomatosis treated with TNFα inhibitors, and it is difficult to determine the effect of treatment using conventional spirometry because the lesions are located in small airways. However, it has been reported that the forced oscillation technique (FOT) is useful in the evaluation of small airway disease in bronchial asthma or chronic obstructive pulmonary disease.

Context.—: Because granulomas are represented in almost every disease category, the number of clinically and pathologically important granulomatous pulmonary diseases is large. Their diagnosis by pathologists is particularly challenging because of their nonspecificity.

Approximately 50% of total cases have been associated with asthma and allergic bronchopulmonary aspergillosis, while it has been rarely reported in the context of rheumatoid arthritis (RA). We describe the case of a 69-year-old female RA patient with BcG presenting as a solitary cavitary pulmonary mass.

Giant cell arteritis (GCA) is a type of large vessel vasculitis, and it involves the aorta, large vessels and terminal branches of the external carotid artery, especially the temporal artery. Temporal artery biopsy is a simple tool for the diagnosis of vasculitis, however, the histopathological findings do not always differentiate between the small-vessel vasculitis and GCA. We report the case of 72-year-old male who initially had a clinical diagnosis of GCA, then in the course of treatment, diagnostic histopathological approach revealed the necrotizing vasculitis with bronchocentric granulomatosis in the inflammatory nodule of the lung.
