Fungus Haematodes. This singular complaint was first distinctly described by Mr. Hey, in his very excellent work, entitled"practical Observations in Surgery." It is a bloody tumour which forms in every part of the body, painful when seated in the muscles; but producing little inconvenience when in the cellular substance. It distends the integuments; but does not,like an abscess, render them thinner. When pressed with the hands, one part will give the sensation of a deep-seated fluid; in another the tumour is hard and uneven. When the integuments burst, the appearances are sometimes those of an excoriation only; sometimes a dark, bloody mass protrudes through the aperture. Where the fungus comes into contact with the muscles, they lose their natural redness and their fibrous appearance, becoming brown, and like the adipose membrane.
When the fungus appears through the skin, it bleeds copiously, and the haemorrhage is frequently repeated till the patient sinks; neither the hydrargyrus nitrarus ruber, the hydrargyrus muriatus, antimonium muria-tum, or undiluted vitriolic acid, can repress its growth. Amputation is the only remedy; and if the tumour has begun at the lower part of a limb, and the slightest portion is left at the upper, the disease returns. It appears to be an organised, and is probably a living, parasitic animal, nourished by the vital fluid of the patient, and capable of absorbing from the subjacent vessels what is effused from its own.
