TROPHONEUROSES. 505 gives a vivid picture of excavation of the sella turcica. A pituitarytumor is not necessarily present. This gland may be compressed byan adjacent growth or influenced by a variety of pathological conditions arising after the attainment of full sexual growthcause, in varying degree, sexual inaptitude, genital atrophy, impotence^and amenorrhea, and may cause more or less Fig. 217.—a--Ray picture of sella turcica, marked +. excavated by pituitary tumor. No acro-megaly present. The treatment must be carefully individualized. Brain tumor con-ditions must be treated on their own surgical indications. Decom-pressive operations are advisable in some instances. When the tumoris definitely limited to the pituitary, it offers an opportunity for abrilliant operation and an equally brilliant result. The cachexiaresulting upon a lack of pituitary function must be combated bypituitary feeding, and this may be tried in the infantile or juvenilecases. Adiposis Dolorosa.—In 1892 F. X. Dercum,1 under the titleAdiposis Dolorosa, described a condition which seems in the adult to beanalogous to the adiposity and genital dystrophy of Froehlich whichoccurs in earlier years. This condition has come to be generally knownas Dercums disease. In the etiology, neuropathic heredity or a personal neuropathic con-dition have not been noted with suf
