tracheia (arteria) windpipe + bronchial tube[s] + pathos suffering, disease; Greek chondros cartilage + osteon bone + plastike of plastic, sculpture; a synonym of hondroosteoplastiche-Skye a bronchopathy] — pathological heterotopic formation of bone and cartilaginous tissue in a mucous membrane of a trachea and bronchial tubes.

It is observed, as a rule, at adults and only in isolated cases — at children. Large, average and small vnutrilegoch-ny bronchial tubes are surprised (see). In a trachea (see) patol. changes are localized, as a rule, in the lower two thirds, on a lobby and sidewalls. The back webby wall of a trachea is surprised seldom.

Patol. cartilaginous and bone growths in respiratory tracts took for tumors (a chondroma, an osteoma) earlier. In a crust, time consider that they can be an ecchondrosis or exostoses (see) cartilages of bronchial tubes or a trachea, the investigation hron. inflammatory processes in walls of bronchial tubes or tracheas, and also anomaly of development of walls of bronchial tubes and tracheas. The last point of view gained the greatest recognition. Sometimes T. x. develops against the background of a local amyloidosis of a trachea (see the Amyloidosis).

Macroscopically on a mucous membrane of a trachea and bronchial tubes the whitish eminences of various size merging sometimes in tyazh with the wrong outlines are visible multiple firm. On a section they are presented by islands of bone or cartilaginous tissue. The bone tissue (see the Bone) these islands has a mature lamellar structure, but maybe coarse-fibered. Bone islands are not connected with the preexisting cartilage. According to various researchers, cartilaginous tissue (see) islands can be fibrous, elastic or hyaline. Certain sites of a neogenic cartilage are under an epithelium. As well as the bone tissue, cartilaginous islands arise irrespective of the preexisting cartilage of a bronchial tube or a trachea. Larger cartilaginous centers are located near the preexisting cartilage, but are usually separated from it by a zone a perikhondriya.

T. x. it is found accidentally at rentgenol more often. research or bronkhoskopiya. In some cases the wedge, manifestations in the form of feeling of dryness in a throat, hoarseness, cough, a pneumorrhagia, a stenosis of a trachea are described. T. x. it can be combined with tracheitis, damage of a trachea at tuberculosis, syphilis and a scleroma, changes at to-rykh are not connected with the centers heterotopic a cartilage - and osteogeneses.

Symptomatic treatment. At the stenosis of a trachea caused by T. x., there can be a need for an operative measure.
