Enlargement of the cervical glands from secondary cancer may simulate tuberculosis, but is differentiated by its association with cancer in the mouth or throat, and by the characteristic, stone-like induration of epithelioma.
The soft parts, including the nail, should be reflected towards the dorsum in the form of a flap, the base of the exostosis divided with the chisel, and the exostosis removed. Malignant disease in relation to the nails is rare. Squamous epithelioma and melanotic cancer are the forms met with. Treatment consists in amputating the digit concerned, and in removing the associated lymph glands.
Lupus usually begins earlier in life, it presents apple-jelly nodules, and lacks the rounded, elevated border. Syphilitic lesions progress more rapidly, and also lack the characteristic margin. The differentiation from squamous epithelioma is of considerable importance, as the latter affection spreads more rapidly, involves the lymph glands early, and is much more dangerous to life. Treatment.
He describes epithelioma very clearly, enumerates its most frequent locations in their order, lays down its bad prognosis, and hence the necessity for early operation with entire removal of the new growth whenever possible. He feared hemorrhage very much, however, and warns with regard to it, and evidently had had some very unfortunate experiences in the treatment of these conditions.
#Cancer.# There are several types of primary cancer of the skin, the most important being squamous epithelioma, rodent cancer, and melanotic cancer. [Illustration: FIG.
The wart horn grows from a warty papilloma of the skin. Cicatrix horns are formed by the heaping up of epidermis in the scars that result from burns. If an ulcer forms at the base of a horn, it may prove the starting-point of epithelioma, and for this reason, as well as for others, horns should be removed. [Illustration: FIG.
Nevertheless, in my enthusiasm, I have diagnosed in this case that a very considerable extent of the cardiac wall was affected by epithelioma. We shall see. Not long since I condemned Tudor to an early and sudden death a death which might be hastened by circumstances. 'Poor chap! Hugo murmured. The dead man looked so young, artless, and content.
The varieties of cancer are distinguished according to the character and arrangement of the epithelial cells. The squamous epithelial cancer or epithelioma originates from a surface covered by squamous epithelium, such as the skin, or the mucous membrane of the mouth, gullet, or larynx.
CLASSIFICATION OF TUMOURS: I. Connective-tissue tumours: Innocent: Lipoma, Xanthoma, Chondroma, Osteoma, Odontoma, Fibroma, Myxoma, Endothelioma, etc.; Malignant: Sarcoma II. Epithelial tumours: Innocent: Papilloma, Adenoma, Cystic Adenoma; Malignant: Epithelioma, Glandular Cancer, Rodent Cancer, Melanotic Cancer III. Dermoids IV. Teratoma.
The term trade epithelioma has been applied to that form met with in those who follow certain occupations, such as paraffin workers and chimney-sweeps.
