fibrosis

 [fi-bro´sis]
formation of fibrous tissue; see also fibroid degeneration. adj., adj fibrot´ic.
congenital hepatic fibrosis a developmental disorder of the liver, marked by formation of irregular broad bands of fibrous tissue containing multiple cysts formed by disordered terminal bile ducts, resulting in vascular constriction and portal hypertension.
cystic fibrosis (cystic fibrosis of pancreas) see cystic fibrosis.
diffuse idiopathic interstitial fibrosis (diffuse interstitial pulmonary fibrosis) idiopathic pulmonary fibrosis.
endomyocardial fibrosis an idiopathic type of myocardiopathy that is endemic in various parts of Africa and rarely in other areas, characterized by cardiomegaly, marked thickening of the endocardium with dense white fibrous tissue that may extend to involve the inner myocardium, and by congestive heart failure.
idiopathic pulmonary fibrosis chronic inflammatory progressive fibrosis of the pulmonary alveolar walls, with steadily progressive dyspnea, resulting in death from oxygen lack or right heart failure. Most cases are of unknown origin, although some are thought to result from pneumoconiosis, hypersensitivity pneumonitis, scleroderma, and other diseases.
mediastinal fibrosis development of hard white fibrous tissue in the upper portion of the mediastinum, sometimes obstructing the air passages and large blood vessels; called also fibrosing or fibrous mediastinitis.
periureteral fibrosis retroperitoneal fibrosis.
pleural fibrosis fibrosis of the visceral pleura so that part or all of a lung becomes covered with a plaque or a thick layer of nonexpansible fibrous tissue. The more extensive form is called fibrothorax.
postfibrinous fibrosis that occurring in tissues in which fibrin has been deposited.
proliferative fibrosis that in which the fibrous elements continue to proliferate after the original causative factor has ceased to operate.
pulmonary fibrosis idiopathic pulmonary fibrosis.
retroperitoneal fibrosis deposition of fibrous tissue in the retroperitoneal space, producing vague abdominal discomfort, and often causing blockage of the ureters, with resultant hydronephrosis and impaired renal function, which may result in renal failure. Called also Ormond disease.
fibrosis u´teri a morbid condition characterized by overgrowth of the smooth muscle and increase in the collagenous fibrous tissue of the uterus, producing a thickened, coarse, tough myometrium.

pleural fibrosis

A condition occurring in pulmonary tuberculosis, asbestosis, and other lung diseases in which the pleura becomes thickened and the pleural space may be obliterated.

Histologically it is characterised by a basket-weave pattern of pleural fibrosis with subpleural parenchymal interstitial fibrosis superficially extending into the underlying lung [5].
Round Atelectasis.--Specimens showing atelectatic lung with apparent fibrosis and overlying pleural fibrosis, especially in patients with a history of pleural effusions, should prompt consideration of round atelectasis.
B, Pleural fibrosis, a result of recurrent or long-standing injury, is a nonspecific finding that can also be seen in connective tissue diseases such as rheumatoid arthritis or systemic lupus erythematosus.
Eleven patients (12% of all patients with SP in the study) were found to have a distinctive pattern of pleural fibrosis with islands of fibroblastic foci within a myxoid stroma at the pleural-parenchymal interface or leading edge.
Intrapleural cysts up to 5 mm were noted in the dense pleural fibrosis. The cysts were lined by reactive hobnail cells, representing either hyperplastic type 2 pneumocytes or mesothelial cells and were, therefore, different from blebs (intrapleural, unlined collections of air).
