Lymphomatoid means lymphoma-like and granulomatosis denotes the microscopic characteristic of the presence of granulomas with polymorphic lymphoid infiltrates and focal necrosis within it. LG most commonly affects middle aged people, [2] but has occasionally been observed in young people. [3] Males are found to be affected twice as often as ...
The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, [4] especially in older adults and smokers. Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. [4]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
"Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not granulomatous. Similarly, radiologists often use the term granuloma when they see a calcified nodule on X-ray or CT scan of the chest. They make this assumption since granulomas usually contain calcium, although the cells that form a ...
While TNF is widely believed to play an important role in the formation of granulomas (this is further supported by the finding that in animal models of mycobacterial granuloma formation inhibition of either TNF or IFN-γ production inhibits granuloma formation), sarcoidosis can and does still develop in those being treated with TNF antagonists ...
ENKTCL-NT is a rare type of lymphoma that commonly involves the nasal cavity, oral cavity, and/or pharynx [5] but less commonly can also involve the eye, larynx, lung, gastrointestinal tract, skin, and various other tissues. [6] Patients presenting with highly localized midline facial disease fit the historical definition of lethal midline ...
Granulomatous–lymphocytic interstitial lung disease (GLILD) is a lung complication of common variable immunodeficiency disorders (CVID). It is seen in approximately 15% of patients with CVID. [1] It has been defined histologically as the presence of (non-caseating) granuloma and lymphoproliferation in the lung. [1]
Chronic granulomatous disease (CGD), also known as Bridges–Good syndrome, chronic granulomatous disorder, and Quie syndrome, [1] is a diverse group of hereditary diseases in which certain cells of the immune system have difficulty forming the reactive oxygen compounds (most importantly the superoxide radical due to defective phagocyte NADPH oxidase) used to kill certain ingested pathogens.
