Fibromata consist of dense connective tissue,usually covered only with a thin layer of stratified orcolumnar epithelium. In shape they are rounded or Fig. Fibroma on the left vocal cord. oval, smooth in contour, and pale in color. They arealmost always attached by a rather broad base (as shownin Fig. 117, in which a fibroma of the left vocal cord isdepicted). Fibromata vary in size from a pins head toa pea. 3. Cysts are usually due to the sealing up of themouths of mucus-secreting glands, and to the retentionin and distention of the ducts of the glands by the secre-tions. Cysts may be small or quite large, and areusually attached by a broad base. Attention has beencalled recently to the fact that the walls of these cystsare in some cases observed to contain giant-cell forma-tion and tubercle bacilli. There may be no other evi-dences of tuberculosis in an individual having such acyst. The positions in which cysts are most commonlyfound are the ventricular bands, ary-epiglottic folds,epiglottic, protruding from the ventricles of the larynx,and, rarely, from the vocal cords. 32 498 DISEASES OF
