[Illustration: FIG. 17.--Infant 11½ months old. Separation of lower epiphysis of femur with marked subperiosteal hemorrhage. Typical periosteal "tags" or "streamers." The connection of these "streamers" with the periosteal layer is evident.] Hess and Unger observed that in several instances where subperiosteal hemorrhage had been diagnosed, X-ray examination disclosed that the swelling of the thigh was due mainly to infiltration of the muscles and subcutaneous tissue. It is surprising how an infiltration of serum gives rise to a swelling which resembles in appearance and consistency the classical subperiosteal tumor. The skin, mucous membranes and subcutaneous tissues are frequently the sites of hemorrhage. There is a difference of opinion as to how frequently petechial hemorrhages occur in scurvy, particularly as to whether they are encountered early in this disorder. Great variation in this regard may be noted in individuals and in groups of cases occurring at different times. In the cases reported in 1914 by Hess and Fish, petechial hemorrhages were frequently an early sign, to such an extent that they led to a study of the blood and blood-vessels in this disorder. The hemorrhages in this "scurvy epidemic" were the result of a complication of scurvy with an infectious disease. It is not necessary, however, for infection to exist to bring about a rupture of the small vessels. The idiosyncrasy of the individual has to be considered as well as the fact that infants have a tendency to develop minute skin hemorrhages, especially such as have an exudative diathesis. In the course of scurvy, petechiæ may be found not only in the skin, but in the mucosa of the mouth, especially overlying the hard palate, and also in the palpebral conjunctiva, identical with the minute petechiæ so significant of general sepsis. In addition to these minute hemorrhages larger ones are not infrequently found in various parts of the body, especially in the neighborhood of the joints. They appear as discolorations of various intensities and shades, and are often interpreted as being merely the result of bruises. These have been encountered most often about the knee-joint, on the forehead, or in the concha of the external ear, where they may best be seen by means of transmitted light. A form of hemorrhage which must be especially mentioned, although it is very infrequent, is that taking place into the orbit, leading to a _proptosis of the eyeball_, usually the left (Still). This sign should be borne in mind, as it occurs occasionally before other symptoms have rendered the diagnosis clear, and may lead to a diagnosis of tumor.
