The diseased parts presented the following appearances. Portions of the acromion process, superior costa, and spine of the scapula, were of their natural appearance. But the coracoid process, the glenoid cavity, and the cervix, were entirely destroyed, and their situation occupied by an irregular broken-down tumour, consisting of osseous spiculæ, and cancelli, irregularly disposed, and forming cavities which were filled with blood, partly fluid and partly coagulated. The head of the humerus was extensively absorbed. The articulating cartilage was almost entirely destroyed, particularly on the inner side, where a large portion of the bony matter had also been removed. The ulcerated surfaces were of a dark, bloody colour.
HYDATIC TUMORS.
Another disease of the bones which ought to be introduced here is the development of hydatids, which I described twelve years ago under the name of osteo-hydatidic tumours. The seat of this affection is not confined to any particular class of bones; though the long are perhaps most prone to it. Its precise nature and origin have not yet been determined; nor are its symptoms such as to enable us, in the present state of our knowledge, to distinguish it from exostosis, osteosarcoma, and other maladies. Its progress is commonly slow, the surface of the tumour is smooth and regular, the skin exhibits no unusual appearance, and the adjacent textures rarely participate in the morbid action. The hydatids, usually of a globular figure, vary greatly in size and number, and are generally filled with a thin, limpid fluid. They appear to be of the nature of acephalocysts. The prognosis unfavourable, owing to the difficulty of destroying these parasites, and their constant tendency, when interfered with, to reappear.
As soon as the true nature of this tumour is ascertained it should be laid freely open, its contents turned out, and the sac destroyed. For this purpose the sides of the cavity should be seared with the actual cautery, or touched with some of the more powerful escharotics, as the nitrate of silver, or the caustic potash. If these measures fail, and the disease involve the whole circumference of the bone, nothing short of amputation will suffice. This was successfully resorted to in one of the cases which came under the observation of Mr. Lucas of London.]
TREATMENT OF TUMOURS.
It may be observed generally, that no benefit can be derived from external applications to tumours, such as friction with liniments or ointments containing iodine, mercury, &c.; and that, therefore, it is injudicious to employ such temporising measures; for though a tumour at its commencement appear to be of a very harmless nature, yet it may soon assume a most malignant character. If an apparently simple tumour increase, and exhibit symptoms of inflammation, it will perhaps be advantageous to apply leeches, to arrest that incited action which affords the accession of new materials; this, however, cannot check the morbid activity inherent in the new formation, though it may hold the growth in check a little. If a tumour is to be removed by external applications, it is evident that these must be such as shall prevent the deposit of new matter, and allow the absorbents to remove that which already exists; for absorption is always going on in a tumour, though it leaves no evidence of its progress, on account of the deposition of new matter exceeding the removal of the old. I must say that I am unacquainted with any remedies capable of performing the above indication. The removal of a swelled gland may occasionally be accelerated by such means when stationary, or on the decline, and before cheesy tubercular unorganized matter is infiltrated into its texture; but to trifle so with a new and independent growth is altogether absurd. The knife only is to be depended on.
Many of the tumours first described have no malignant disposition originally, and only require surgical interference when they produce deformity or inconvenience from their bulk. Yet even these ought not to be allowed to attain any great size, however indolent they may appear at first, and however little pain they may produce; for there is always a danger of their assuming a malignant tendency, or forming connections with important parts, so as to render their removal either altogether impracticable, or at least attended with much difficulty. Tumours of every kind, when seated near important organs, must be early removed. Glandular tumours, however, even when of great size and long continuance, are not to be rashly interfered with, when they arise from irritation in the neighbourhood.
Those in which it is feared that malignant action has commenced cannot be trifled with; and the only means which afford a chance of the patient’s being effectually delivered from them is an operation. With a view to their complete extirpation, the external incisions ought always to be free, so as to admit of the after-dissection being easily and rapidly performed: they ought also to be made in the direction of the muscular fibres, whether these lie above or beneath the tumour. In this way the margins of the wound are easily brought into apposition, and there retained; whereas, if the fibres be divided transversely, the wound will gape, and union by the first intention be rendered absolutely impossible. If there is no reason to suppose that the tumour is malignant, little or no integument ought to be removed, unless the growth is of a large size; but, when malignity is dreaded, all the discoloured, tense, and adherent integument, all that is permeated by dilated and tortuous vessels, ought to be taken away, and the incisions made at a distance from the disease. In all cases they ought to commence at the point where the principal vessels enter; these are thus divided at the outset, can be readily secured by ligature, or by the fingers of an assistant, and the dissection is proceeded in without risk or interruption from farther hemorrhage. If the opposite course be pursued, the vessels will be divided two or more times during the operation, and thus the performance of it will either be delayed by the application of numerous ligatures, or will be attended with a considerable loss of blood. After the tumour has been exposed it ought to be principally detached in one direction, as in this way its removal will be sooner accomplished, and not first cut on one side and then on another. If malignant, great care should be taken that all the diseased mass be removed, for a minute portion remaining will form a nucleus in which similar diseased actions are certain to arise; in most instances, it will be prudent not only to remove the parts actually diseased, but those also which are in immediate connection with the tumour, though at the time they appear healthy. All important parts must be carefully avoided. After removal of the mass, and the complete cessation of bleeding, the edges of the wound must be approximated, so as to favour union by the first intention; if this fail, granulation must be promoted, and the wound dressed according to the particular circumstances of the case. All operations on malignant tumours, in their advanced stages, are unwarrantable; they are necessarily painful and severe, and cruel because unavailing; they often, indeed, expedite the dissolution of the patient. If the integuments over the tumour have ulcerated, and if the lymphatics in the neighbourhood are diseased, the disease if removed will certainly be reproduced, and the succeeding tumour will be still more malignant. The operation ought, if at all, to be performed when the disease is in its incipient state, for then only can success be expected.
Exostoses need not to be interfered with, unless they are the source of much inconvenience, either from their size and form, or from their having been detached, and lodged amongst the adjacent soft parts. If loose, they can be removed in the same way as any other extraneous body; if firm, their attachment must be divided by a saw, or by cutting pliers, close to the bone from which they spring. Sometimes, as in the scapula or other flat bone, a portion of the original bony tissue can be cut out along with the new growth, and this renders the chance of any return of disease much less likely.
