A name given to tumours, which occur in mucous membranes especially; and which have been compared to certain zoophytes. Polypi may form on every mucous membrane. They are most commonly observed in the nasal fossae, pharynx, and uterus; more rarely in the stomach, intestines, bronchial tubes, bladder, and meatus auditorius externus. They vary much in size, number, mode of adhesion, and intimate nature. Accordingly, they have received various appellations; mucous, soft, vesic'ular, when their substance has been soft, spongy, vesicular, and, as it were, gorged with fluid. Others have been called hard; and these have been distinguished into fibrous or fleshy, and into scirrhous or cancerous. Fibrous polypi, Pol'ypi fibro'si, Inopol'ypi, are of a dense, compact texture, and whitish colour. They contain few vessels, and do not degenerate into cancer. The scirrhous or carcinom'atous are true cancerous tumours, painful and bleeding. They present all the pathological changes which belong to cancerous affections, and the prognosis is of course unfavourable. The mode of treating polypi must differ according to their character. The means used to destroy them have been, 1. To subject them to the action of certain astringent powders or solutions, to obtain their resolution. 2. Cauterization or the application of the actual cautery or caustics. 3. Excision or ablation with a cutting instrument. Extirpation with the fingers or with the polypus forceps. 5. A ligature, put round them so as to prevent their nutrition. A seton has, also, been sometimes used to gradually destroy the pedicle. The term Polypi, Pseudopol'ypi, Cardi'tit polypo'sa, Pol'ypiform Concre'tions, (F.) Concretions polypeuses ou polypiformes ou sanguines du Coeur, Hemocardioplasties, (Piorry,) has likewise been applied to collections of blood-fibrinous concretions- found in the heart or great vessels after dissolution. These were once, erroneously, regarded as morbid. The presence of these concretions may be suspected, when in the course of an acute or chronic affection of the heart, or at the close of chronic diseases in general-especially those of the lungs -the heart's action becomes suddenly tumultuous, obscure, and accompanied with a soft bellows' murmur, whilst the general symptoms indicate the effects of obstructed circulation. The right cavities are most frequently affected.
