"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 ...
Human eosinophilic granuloma is characterized by abnormal proliferation of Langerhans cells (LCs). LCs are antigen-presenting cells derived from dendritic cells. In humans, eosinophilic granulomas are considered as a benign tumors that occurs mainly in children and adolescents. EG is a quite rare condition, and its incidence is higher in white ...
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 ]
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 ...
Parenchymal hamartoma of the lung. The surrounding lung falls away from the well-circumscribed mass, a typical feature of these lesions. The hamartoma shows a variegated yellow and white appearance, which corresponds respectively to fat and cartilage. About 5–8% of all solitary lung nodules and about 75% of all benign lung tumors, are ...
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]

If occurring in the skin, pneumocystosis most often presents as nodular growths in the ear canals of a person with HIV/AIDS. [3] [6] There may be fluid in the ear. [6] Skin involvement may appear outside the ear, usually palms, soles or underarms; as a rash, or small bumps with a dip. [6] It can occur on the face as brownish bumps and plaques. [6]
