Psammomata are fairly common intra-cranial tumors, and though benign, they may destroy the patient throughgradually increasing intracranial pressure. A chondroma is a tumor composed of hyaline cartilage. It is usu-ally found connected with the epiphyses of the long bones. Chondro-mata are dense, hard, and immovable when young; but when maturethey may be the seat of cystic degeneration. They may become calci-fied or ossified. The treatment of chondromata is not always easy. Obviously, theycall for thorough excision, but thorough excision, if it compromise the. ^ Fig. 519.—Diffuse lipoma TMassachusetts General Hospital). epiphyses of the long bones of young persons, may result in a permanentshortening of the limb. On the other hand, the chondroma ma}- attaina great size, and may so far involve the integrity of the bone that itsremoval implies the amputation of the limb. One may see that theremoval of chondromata may call for the highest degree of experienceand skill, and that each individual case must be treated upon its individ-ual merits. An osteoma is a bone tumor, which we must distinguish from anexostosis and from an odontoma. Exostoses are irregular outgrowthsof bone, while osteomata are distinct tumors composed of bone-liketissue; and odontomata are tumors of dental origin and , osteomata may be regarded as ossifying chondromata.
