Pulmonary lymphangioleiomyomatosis
Lymphangiomyocytosis is defined as a multifocal neoplasm with differentiation of the perivascular epithelioid cell that involves multiple organs.[1]
- Lymphangiomyomatosis is the result of disorderly smooth muscle proliferation throughout the bronchioles, alveolar septa, perivascular spaces, and lymphatics, resulting in the obstruction of small airways (leading to pulmonary cyst formation and pneumothorax) and lymphatics (leading to chylous pleural effusion).
- LAM occurs in a sporadic form, which only affects females, who are usually of childbearing age.

Pulmonary hemorrhage syndromes
Pulmonary hemorrhage syndromes might cause interstitial lung disease.
- There are several pulmonary hemorrhage syndromes that affect the lung parenchyma and eventually lead to pulmonary fibrosis. Some of them are as follow:
- Goodpasture syndrome
- Idiopathic pulmonary hemosiderosis
- Isolated pulmonary capillaritis
Granulomatous lung response
- Hypersensitivity pneumonitis
- Sarcoidosis
- Granulomatous vasculitides
- Granulomatosis with polyangiitis (Wegener)
- Eosinophilic granulomatosis with polyangiitis (Churg Strauss)
- Bronchocentric granulomatosis
