e section of the affected masses before this time has been known to be followed by amaurosis； convulsions； apoplexy； epilepsy； and even death。 Alarmed or taught by such occurrences； the common people often went about all their lives with the plica gradually dropping off。 Formerly there was much theorizing and discussion regarding the etiology and pathology of plica； but since this mysterious affection has been proved to be nothing more than the product of neglect； and the matting due to the inflammatory exudation； excited by innumerable pediculi； agglutinating the hair together； the term is now scarcely mentioned in dermatologic works。 Crocker speaks of a rare form which he entitles neuropathic plica； and cites two cases； one reported by Le Page whose specimen is in the Royal College of Surgeons Museum； and the other was in a Hindoo described by Pestonji。 Both occurred in young women； and in both it came on after washing the hair in warm water； one in a few minutes； and the other in a few hours。 The hair was drawn up into a hard tangled lump； impossible to unravel； limited to the right side in Le Page's patient； who had very long hair； and in Pestonji's case to the back of the head； where on each side was an elongated mass； very hard and firm； like a rope and about the size of the fist。 There was no reason to believe that it was ascribable to imposture； the Hindoo woman cut the lumps off herself and threw them away。 Le Page found the most contracted hairs flattened。 Stellwagon reports a case of plica in a woman。 It occupied a dollar…sized area above the nape of the neck； and in twelve years reached the length of 12 feet。 There was no history of its manner of onset。
Tinea nodosa is a name given by Morris and Cheadle to a case of nodular growth on the beard and whiskers of a young man。 In a case noticed by Crocker this disease affected the left side of the mustache of a medical man； who complained that the hair； if twisted up； stuck together。 When disintegrated the secretion in this case seemed to be composed of fungous spores。 Epithelium fragments； probably portions of the internal root…sheath； sometimes adhere to the shaft of the hair as it grows up； and look like concretions。 Crocker states that he is informed by White of Boston that this disease is common in America in association with alopecia furfuracea； and is erroneously thought to be the cause of the loss of hair； hence the popular name； 〃hair…eaters。〃
Thomson describes a case of mycosis fungoides in a young girl of the age of fourteen； whom he saw in Brussels toward the end of October； 1893。 She was the third of a family of 13 children of whom only five survived。 Of the children born subsequently to the patient； the first were either premature or died a few days after their births。 The seventh was under treatment for interstitial keratitis and tuberculous ulceration of the lips and throat。 The disease in the patient made its appearance about seven months previously； as a small raised spot in the middle of the back just above the buttocks。 Many of the patches coalesced。 At the time of report the lumbar region was the seat of the disease； the affection here presenting a most peculiar appearance； looking as if an enormous butterfly had alighted on the patient's back； with its dark blue wings covered with silvery scales； widely expanded。 The patient was not anemic and appeared to be in the best of health。 None of the glands were affected。 According to Thomson there is little doubt that this disease is caused by non…pyogenic bacteria gaining access to the sweat…glands。 The irritation produced by their presence gives rise to proliferation of the connective…tissue corpuscles。
Jamieson reports a case of mycosis in a native of Aberdeenshire aged thirty…eight。 There was no history of any previous illness。 The disease began three years previous to his application for treatment； as a red； itching； small spot on the cheek。 Two years later lumps presented themselves； at first upon his shoulders。 The first thing to strike an observer was the offensive odor about the patient。 In the hospital wards it made all the occupants sick。 The various stages of the disease were marked upon the different parts of the body。 On the chest and abdomen it resembled an eczema； on the shoulders there were brown； pinkish…red areas。 On the scalp the hair was scanty； the eye…brows denuded； and the eyelashes absent。 The forehead was leonine in aspect。 From between the various nodosities a continual discharge exuded； the nodosities being markedly irregular over the limbs。 The backs of the hands； the dorsums of the feet； the wrists and ankles； had closely approximating growths upon them； while under the thick epidermis of the palms of the hands were blisters。 Itching was intense。 The patient became emaciated and died thirteen days after his admission into the hospital。 A histologic examination showed the sarcomatous nature of the various growths。 The disease differed from 〃button…scurvy。〃 Mycosis fungoides approximates； clinically and histologically； granulomata and sarcomata。
Morris described an interesting case of universal dermatitis； probably a rare variety of mycosis fungoides。 The patient had for many years a disease which had first appeared on the arms and legs； and which was usually regarded by the physicians who saw the case as eczema。 At times the disease would entirely disappear； but it relapsed； especially during visits to India。 At the time the patient came under the care of Morris； his general health seemed unaffected。 The skin of the whole body； except the face； the scalp； and the front of the chest； was of a mahogany color。 The skin of the lips was so thickened that it could not be pinched into folds； and was of a mottled appearance； due to hemorrhagic spots。 All over the thickened and reddened surface were scattered crops of vesicles and boils。 The nails were deformed； and the toes beyond the nails were tense with a serous accumulation。 The glands in the right axilla and the groin were much enlarged。 The hair on the pubes had disappeared。 The abdomen was in a condition similar to that upon the limbs； but less in degree。 The front of the chest below the nipples was covered with dark papules the size of a pin's head。 The back； the buttocks； the face； and the scalp presented similar lesions。 The most striking lesions were three ulcersone on the back of the right hand； one on the right temple； and the other on the left cheek。 The largest was the size of a florin； and had elevated borders； somewhat infiltrated； they were covered with a brown； dry scab。 The patient suffered from itching at night so that he could not sleep。 He was kept under observation； and in spite of treatment the malady advanced in a periodic manner； each exacerbation being preceded by a feeling of tension in the parts； after which a crop of vesicles would appear。 Sometimes； especially on the feet； bullae formed。 The patient finally left the hospital and died of an intercurrent attack of pneumonia。 A microscopic examination revealed a condition which might be found with a number of the chronic affections of the skin； but； in addition； there were certain cell…inclusions which were thought to represent psorosperms。 Morris
