| brown induration of the lung | A condition characterised by firmness of the lungs, and a brown colour associated with haemosiderin-pigmented macrophages in alveoli, consequent upon long-continued congestion due to heart disease. Synonym: pigment induration of the lung. (05 Mar 2000) |
|---|---|
| red induration | A condition observed in lungs in which there is an advanced degree of acute passive congestion, or acute pneumonitis (sometimes termed interstitial pneumonia), or a similar pathologic process. (05 Mar 2000) |
| penile induration | A disease of unknown aetiology in which there are plaques or strands of dense fibrous tissue causing induration of the corpora cavernosa of the penis. The condition produces a painful deformity and is sometimes seen in cases of dupuytren's contracture. (12 Dec 1998) |
| gray induration | A condition occurring in lungs during and after pneumonic processes in which there is failure of resolution; there is a conspicuous increase in fibrous connective tissue in the walls of the alveoli, and also within the alveoli (e.g., fibrous organization of exudate); in contrast to brown induration, there is usually not a prominent degree of pigmentation, unless chronic passive congestion is also present.

| pigment induration of the lung | A condition characterised by firmness of the lungs, and a brown colour associated with haemosiderin-pigmented macrophages in alveoli, consequent upon long-continued congestion due to heart disease. Synonym: pigment induration of the lung. (05 Mar 2000) |
| plastic induration | Sclerosis of corpus cavernosum of penis. (05 Mar 2000) |
| cyanotic induration | Induration related to persistent, chronic venous congestion in an organ or tissue, frequently resulting in fibrous thickening of the walls of the veins and eventual fibrosis of adjacent tissue; the affected tissue becomes firmer than normal, and tends to have an unusual, red-blue colour.

| Froriep's induration | Induration of a muscle through an interstitial growth of fibrous tissue. Synonym: Froriep's induration, interstitial myositis, myofascitis. (05 Mar 2000) |
