DISEASES OF THE SKIN AND CELLULAR TISSUE.
Besides the eruptive fevers, Moreau has found different colorings of the skin in the dead infant; Naege16, Edis and 011ivier d'Angers, mace ration and changes in the epidermis of a living child; Dohrn, inflam matiOn of the skin; Houel, a case of hypertrophy with icthyosis: Char pentier, an identical case, 1877; Simpson, icthyosis; W. Smellie, ictliyosis. Finally, pemphigus has been noted, which, according to Rceser, 1876, is always syphilitic. Still, cases of non-syphilitic pemphigus have been seen by Krauss, Hervieux, Hassan-Mahmoud, Faloy and Des rnelles. One of the most interesting is that of Lorain and Prevost. There existed in a syphilitic infant pemphigus, and also changes in the lungs. Finally, Ammon has cited a case of melanosis of the eyes, and Lobstein a case of cirrhosis. Simpson has described certain tumors of the cervical region, and spina bifida. Meckel and Otto, a cystic tumor of the cellular tissue, situated at the posterior part of the neck, divided into two lateral and symmetrical lobes, by the ligamentum nuclue. Berndt, Omar Hawkins, Beatty, Muller and Henke, cystic congenital tumors of the neck. Simpson, cystic tumors, whose mass consisted of the union of little cells, filled with a thick glairy liquid, at the upper part of the neck, and projecting more or less into the mouth. Wallmann has
described a similar case. These are true ranuhe, consisting of hyper trophied salivary glands. Simpson, tumors in the cervical region, formed by vascular erectile tissue, deeply situated and disappearing on pressure, —on the contrary, increased by crying or efforts. One of these was operated on later; there was profuse hemorrhage. Under the name of bronchocele, has been described congenital hypertrophy of the thyroid gland; this may disappear after some years; Simpson has seen 5 cases of it. 011ivier. has seen in front and to the right of the neck, a tumor, the size of a hazel-nut, of a whitish-yellow color, soft and fluctuating, which yielded pus. Planteau, in 1876, collected a number of cases of cervical tumors. Riveau Landreau has noted a case of purulent ophthalmia, supervening during uterine life.
Taylor records abscesses in the fcetus; Finnell, intra-abdominal tumors; Legendre, hydrocele of the cord; Friedreich, cancer. The intra uterine fcetal pathology is, however, as yet hardly outlined.
