Generalized progressive atrophy leads to a condition that simulates the appearance of a "living skeleton." Facial hemiatrophy is an incurable disease, as yet of unknown pathology. It consists of wasting of the bones, subcutaneous tissues, and muscles of one-half of the face or head, the muscles suffering but slightly.
Burr contributes an exhaustive paper on hemiatrophy of the tongue with report of a case as follows: "L. B., female, mulatto, thirty-one years old, married, came to the Medico-Chirurgical Hospital, Philadelphia, September 23, 1895, complaining that her 'tongue was crooked. Save that she had had syphilis, her personal history is negative.
It is a chronic affection, usually beginning in early life, increasing slowly for years, and then becoming stationary. It is distinguished from one-sided muscular atrophy by the electric reaction, which is not lost in the facial muscles in facial hemiatrophy, and there is no atrophy of other muscles of the body.
