In a cohort of 59 CVID patients with granulomatous disease, 30 (51%) of whom had lung involvement, complete remission of disease was obtained in 5 of 25 attempts using corticosteroids (three patients), methotrexate (1 patient) and cyclophosphamide (1 patient). [2] Partial responses were also seen with rituximab and hydroxychloroquine.
Sarcoidosis of the lung is primarily an interstitial lung disease in which the inflammatory process involves the alveoli, small bronchi, and small blood vessels. [29] In acute and subacute cases, physical examination usually reveals dry crackles. [28] At least 5% of cases include pulmonary arterial hypertension.
Pulmonary hyalinizing granuloma is characterized by localized changes in lung architecture determined by deposition of hyaline collagenous fibrosis accompanied by sparse lymphocytic infiltrate that compresses and distorts the remaining bronchioles. A higher magnification, the mass is composed by hypocellular collagen lamellae. [3]
The nuclei form a circle or semicircle similar to the shape of a horseshoe away from the center of the cell. Langhans giant cell was typically associated with tuberculosis but has been found to occur in many types of granulomatous diseases. Langhans giant cell could be closely related to tuberculosis, syphilis, sarcoidosis, and deep fungal ...
A granuloma is an aggregation of macrophages (along with other cells) that forms in response to chronic inflammation. This occurs when the immune system attempts to isolate foreign substances that it is otherwise unable to eliminate. [ 1 ]
Granulation tissue with a poorly formed granuloma to the left of centre. Within this area there is a multinucleate giant cell of the Langhans type. The patient had a healing mycobacterial infection of the skin (Mycobacterium ulcerans infection). Langhans giant cells (LGC) are giant cells found in granulomatous conditions.
On rare occasions, thoracoscopic lung biopsy is required. On histopathological examination, a biopsy will show leukocytoclastic vasculitis with necrotic changes and granulomatous inflammation (clumps of typically arranged white blood cells) on microscopy. These granulomas are the main reason for the name granulomatosis with polyangiitis ...
The inflammatory process that creates these cells often leads to a foreign body granuloma. The human body goes through several steps when exposed to foreign biomaterial including acute and chronic inflammation , and formation of new tissue and a fibrous capsule along the surface of the implantation.
