skin to be noted are cleanliness, elasticity, general nutrition, moisture, presence of scales, atrophy, hyperplasia (ichthyosis, horny warts, cutaneous horns, the various forms of elephantiasis), scleroderma, keloid, xeroderma pigmentosum, albinism, leucoderma, vitiligo, myxœdema, seborrhœa, alopecia, erysipelas, dermatomyositis, psoriasis, impetigo, rhinophyma, herpes, miliaria, sudamina, symmetrical gangrene, trophic changes, “goose-flesh,” hemorrhages, scars, tattoo-marks, etc. The various forms of skin-diseases should be described and recorded whenever present. The presence of petechiæ or ecchymoses in the skin (purpura) is characteristic of all the forms of essential purpura (simplex, peliosis rheumatica, hæmorrhagica, senilis, morbus maculosis Werlhofii, scurvy, Möller-Barlow disease, etc.); such skin hemorrhages occur also as the result of trauma, congenital hæmophilia, in the course of many infections (small-pox, plague, typhus, yellow fever, endocarditis, measles, scarlet fever, septicæmia, pyæmia, rheumatism, meningitis, typhoid fever), in many intoxications (snake-bite, icterus, nephritis, iodine, bromine, phosphorus, chloroform, etc.), also in severe anæmia, pernicious anæmia, leukæmia, sarcoma, carcinoma, acute yellow atrophy of the liver, hysteria, vicarious menstruation, reflex hemorrhages, stigmatization, etc. The number, size, color and location of all cutaneous hemorrhages should be recorded. 24. =Hair.= Color, abundance, distribution, character, quality, condition, length, pathologic conditions (alopecia areati, senilis, præsenilis, pityrodes, syphilitica and symptomatica, trichorrhexis nodosa, hypertrichosis, parasites, etc.). In prolonged fevers and wasting diseases the diameter of the hair is diminished. Symptomatic alopecia occurs after syphilis, typhoid fever, scarlet fever, measles, erysipelas, anæmia, Roentgen irradiation, etc. The length, color and quality of the hair as well as amount and distribution vary in different races. Hypertrichosis is often associated with degeneracy, criminal tendency, epilepsy, idiocy and certain forms of insanity. An apparent growth of hair after death may be caused by retraction of the tissues; an actual postmortem growth is not conceded by the majority of authorities in spite of the numerous tales to that effect. Loss or absence of pigment is seen in albinism, leukotrichia due to infection, Graves’ disease, exposure, burns, nervous affections, fright, worry, etc. The presence on or about the body of hairs not belonging to the cadaver is a point of great importance in medicolegal cases and one that should be thoroughly investigated as to their source. Human hair can be identified microscopically, and it is possible to recognize different specimens according to their variation in color, length, quality, etc.
