A system of surgery : pathological, diagnostic, therapeutic, and operative . r-face of the morbid growth, and dipping into its interior. The outer table of thebone is transformed into a thin, parchment-like lamella, perforated in variousplaces, or entirely destroyed by absorption. A section of the tumor usuallyexhibits, in addition to the appearance just described, osseous fragments, or piecesof fibro-cartilage. The superincumbent integuments, traversfed by large bluishveins, are at first soft and glossy; but at length, from the constant and increasingpressure exerted upon them, they ulcerate, and allow the fungous mass to pro-trude. Some of the more extraordinary alterations which the osseous structure iscapable of undergoing in this disease are well seen in fig. 332, from a specimenin the cabinet of Professor Buchanan. The patient was a mulatto girl, about CHAP. VIII. MALIGNANT FORMATIONS. 845 twelve years of age, who had labored for some time under a large, lobulatedtumor, partly elastic and partly inelastic, situated in the lower part of the leg, Fig. Enceplialoid of the tibia. and attended with great dilatation and distension of the subcutaneous being performed, the stump healed kindly, and for several weeksthe girl did well; but in a few months she began to complain of pain in her hipand side, and she died in less than a year, apparently from internal malignantdisease. A section of the tumor displayed an immense number of osseousspicules, of extraordinary length and delicacy,whose intervals were occupied partly by car-tilaginous and partly by gelatinous substance,with here and there a cyst containing bloody-looking matter. The external characters ofencephaloid are well displayed in the adjoin-ing cut, fig. 333, from a specimen in my col-lection. 2. Of colloid of the osseous tissue verylittle is known. It is most frequently metwith in the diseased conditions of the bonesdenominated osteosarcoma and spina ventosa. Fig. 334.
