generally diminishes in size from absorption of the fatty matter; the nipple is retracted, often to a great degree, and the surrounding integuments are of a purplish hue, and exude a sanious fluid; at length the nipple is completely destroyed by ulceration. In other instances the tumour is large, and there is a hard œdema of the integuments; the skin is thick, coarse, and of a dark red colour. The tumour soon adheres immoveably to the subjacent muscles and ribs, converting the contiguous portion of the former into a substance similar to itself. There may be other varieties in the appearances and symptoms of carcinoma; but the above are those which are most frequently observed, and are sufficient to denote the general character of this species of tumour, and to show its peculiar and inveterate malignancy.

      Ulcers or swellings, at first simple, may assume a malignant action, either carcinomatous or of another kind; thus, in one instance, a simple ulcer, produced by a burn, assumed a foul and unhealthy aspect; and ultimately degenerated into a most malignant sore. Various malignant actions commence in glands of the conglobate or conglomerate kind, at first simply enlarged from irritation or injury. The female breast often becomes indurated from a blow, or from milk abscess, and remains for a series of years, half a lifetime perhaps, without any perceptible change in the enlargement and induration; but the tumour frequently is roused into activity at the critical time of life, and malignant action ultimately commences. The menstrual period ought to be particularly attended to in affections of the mamma more especially, but also in all tumours and ulcers; for both during and before it tumours become larger and more painful, the whole system appears to be excited, then relaxed, and all morbid actions seem to possess increased activity.

      In this disease, as in soft cancer, as it has been called, (and they occasionally pass into each other,) the bloody masses, or sacs containing bloody fluid, are to be dreaded, and when they exist are to be considered as very unfavourable; for if, on the removal of a carcinomatous tumour, such appearances be found, the disease will certainly return; a new tumour, of even a worse character than the preceding, will be formed; a fungus will be protruded, and from this hemorrhage will occur.

      The lymphatic glands, both above and below the tumour, generally enlarge early in the disease, become hard, and cut like cartilage, and with a grating noise. Frequently they become converted into a dense and fibrous substance, resembling carcinoma; sometimes they are softened and broken down at several points, and contain a purulent or bloody fluid. They enlarge, coalesce, and form irregular masses, which rise more and more above the surface; the superimposed integuments give way, and then occur those destructive ravages by ulceration and sloughing already described. The lymphatic vessels entering these tumours and emerging from them feel hard and wiry, as if thickened. The integuments in the neighbourhood of the tumours, and in the course of these absorbents, are of a blue colour, and the veins enlarged and tortuous; the limb below the enlargement swells and is œdematous. The absorbents often become affected months or even years after the removal of the original and exciting tumour; the immediate cause being taken away, yet the inherent disposition to malignant action is too often left, not to be eradicated. In fact, the disease generally returns, either in the original integuments, in the form of tubercles or buds, in the cicatrix, or in the glands; very frequently all are affected. It seems also to spring not unfrequently from fascia. Such enlargements of the glands have been said to arise, in the first instance, from irritation, and not from any participation in malignant action; and on this supposition, though in general extremely incorrect, cruel, bloody, and unnecessary operations have been performed.

      Cancer seizes either the mucous or the cutaneous surface, with hardness and a warty excrescence; this ulcerates, and is surrounded by a hardened base. The process of destruction advances, and the ulcerated part presents the same appearances as those of a sore arising from a similar action in a deeply-seated carcinomatous tumour. The glands also enlarge, and assume the same aspect as if they had been the original seat of the disease. Some pathologists seem disposed to deny this, but apparently on no very sufficient grounds.

FUNGUS HÆMATODES

      Has been much confounded with medullary sarcoma, but the two diseases are materially different. Fungus hæmatodes almost always supervenes on other morbid formations, when they have been ulcerated and exposed; and the particular formation which most frequently precedes is the medullo-sarcomatous; a bleeding fungus, however, occasionally protrudes from tumours of a different character, which, though they may have been at first simple, have degenerated, ulcerated, and assumed a malignant action. The disease certainly does not occur so frequently as some have asserted; for many, instead of limiting the application of the term to those fungous protrusions which bleed, honour with the appellation of fungus hæmatodes every growth which protrudes after the ulceration of a tumour, and every tumour which is unusually prominent, of soft consistence, and of a somewhat fungous appearance, although such have never shown any disposition to bleed, either spontaneously, or from irritation. But fungus hæmatodes, as the name implies, is truly a fungus which resembles blood; and as bloody or blood-like tumours are formed from the rupture of some vessel of rather a large size, and as they almost invariably evince a tendency to profuse hemorrhage, as a necessary consequence of the mode of their formation, the term is correctly applied only to those fungous growths which either have at one time emitted a discharge of blood, and exhibit symptoms of a recurrence of the hemorrhage, or which frequently pour out a quantity of blood, sometimes inconsiderable, but often profuse, and generally altogether uncontrollable. In short, the circumstances necessary to entitle a morbid formation to the appellation of fungus hæmatodes are a fungous structure and appearance, and hemorrhage proceeding from it to a greater or less degree, and with more or less frequency. Fungi are frequently met with, but there are certainly few hæmatoid fungi.

      The excrescence is generally of a dark colour, resembling a mass of coagulated blood, but of more soft consistence, and its extremity has often a sloughy appearance. It is evidently organised; for, on being injured even in a very slight degree, hemorrhage ensues from the part which has been broken or contused, and frequently the growth bleeds spontaneously. At first the hemorrhage is in general slight, but is often repeated, becomes very profuse, and in most instances cannot be arrested. The vessels in the substance of the morbid mass are diseased in their coats, and have altogether lost their power of contraction; they give way either spontaneously or by laceration, and by their non-contraction they appear to serve merely as passive tubes, through which the blood is poured out by the active vessels which supply them; the latter are not exposed to any of the causes which tend to produce speedy obstruction of their canals, therefore continue to transmit their contained fluid through their subservient branches, and from this the uncontrollable nature of the hemorrhage can be accounted for; from the number of vessels which supply the new structure, and which are thus employed, it can be readily imagined that the hemorrhage will be profuse. In many instances, the application of firm pressure on the limb above the seat of the disease is even insufficient to arrest the flow of blood; and though this may, in some degree, be explained by supposing the continued stream to be venous, still it must be confessed that the disease appears connected with a peculiar hemorrhagic tendency. Frequently the fungus is found to communicate with, or rather to arise from, numerous cysts of a glossy appearance, from which also blood is copiously effused. The surrounding tissues are completely disorganised in the immediate neighbourhood, and also much altered in structure for a considerable extent around; the muscles, besides their disorganisation, have acquired a peculiar brown hue. Sometimes the hemorrhage does not seem to proceed so much from the fungus as from the subjacent cysts; for when a superficial incision or puncture is made into it, the bleeding is often inconsiderable, and only becomes alarming after masses of coagulated blood have been removed, and the cysts thereby exposed. Occasionally the fungus communicates with a cavity of enormous size, filled with blood, partly coagulated and partly fluid, and from the parietes of which the hemorrhage proceeds. When the disease has supervened on a medullo-sarcomatous tumour, the coagulated blood is mixed with a substance resembling the brain in a state of putrescence. It may supervene on polypous tumours, particularly of the antrum; and of this I have seen several instances. Sometimes it is produced after the removal of a tumour apparently not of malignant character, and in this case it frequently does not appear till the wound has almost cicatrised.
