In TUBERCULOSIS AND SYPHILIS 381 isolated cases, however, a restoration of the destroyed muscle-fibresby regeneration does seem to take place, at least partially. A special form of chronic muscular inflammation is myositis ossi-ficans, which results in new formation of bone in the muscles andtendons after the model of periosteal bone-development (pp. 358-9).It may occur spontaneously, or as the result of injuries, in isolatedmuscles (the deltoid, biceps of the arm or adductors of the thigh,the condition being then spoken of respectively as drill-hone orriders-bone), or it may affect most or even all of the muscles ofthe body in succession. Tuberculosis occurring primarily in muscle is certainly very rare. h. Fig. 194.—Spindle-Celled Sarcoma of the Muscular Tissue of the 285. (Alum cochineal.) a, Bundles of spindle cells, in longitudinal and trans-verse section, usurping the place of the primitive muscle bundles ; h, Blood-vessels. Most frequently it spreads to the muscular tissue from the surround-ing parts, in which case it takes the form of caseous nodes,abscesses, fistulae, and so forth. Syphilis may exist in the muscles in the form either of gummataor of a more diffuse affection. In the latter case the endomysiumin the neighbourhood of the blood-vessels is found infiltrated withsmall cells, and the muscle corpuscles are also seen to be under-going proliferation. These changes either subside again or leadeventually to cicatricial thickening of the intramuscular connectivetissue and to atrophy of the muscular fibres. Of primary new-formations the sarcomata occur most frequently. 382 THE MUSCU
