endomyocardial fibrosis  idiopathic myocardiopathy seen endemically in parts of Africa and less often in other areas, characterized by cardiomegaly, thickening of the endocardium with dense, white fibrous tissue that often extends to involve the inner third or half of the myocardium, and congestive heart failure.

idiopathic pulmonary fibrosis  chronic inflammation and progessive fibrosis of the pulmonary alveolar walls, with progressive dyspnea and potentially fatal lack of oxygen or right heart failure. The acute form is called Hamman-Rich syndrome.

mediastinal fibrosis  fibrous mediastinitis; development of white, hard fibrous tissue in the upper portion of the mediastinum, sometimes obstructing the air passages and large blood vessels.

nodular subepidermal fibrosis 

1. benign fibrous histiocytoma.

2. a type of benign fibrous histiocytoma marked by subepidermal formation of fibrous nodules as a result of productive inflammation.
