Degenerations of a similar kind as those of the abdominal recti were found in both pectorals. In the chest region, however, the degeneration was less frequent and less severe. We observed it only twice, and in neither instance had the degeneration led to a rupture and hemorrhage of the muscle bundles. Kuskow observed a single case of degeneration and hemorrhage of the pectoral muscles. In the psoas muscle we observed degeneration on two occasions, in one of which the lesion was associated with a partial separation of the muscle fibers and hemorrhages into its substance. In one case clinically, but not coming to autopsy, a lesion, which from its character we presume to have been a degeneration, occurred in the sterno-mastoid, being accompanied by hemorrhage and the development of a firm clot the size of a hazel nut. In the subsequent history of this case the lesion passed through an aseptic process of organization with contracture so that the patient has recently been developing a “wryneck.” Kohts in 1890 reported the finding of muscle degeneration and abscesses in the arm. The condition arose as a late complication of influenza. From our experience at the autopsy table in observing the relative frequency with which muscle degeneration occurs in the severe cases of epidemic influenza, we feel convinced that numerous cases which recover pass undiagnosed of this condition. Furthermore we have evidence, as illustrated in a case observed by Dr. McMeans, wherein a lesion which occurred in the gluteal muscles was followed by a localizing infection at this site that these muscle degenerations and hemorrhages may have serious consequences. There are a number of instances in which post-influenzal complications of the nature of deep-seated abscesses of the extremities, thorax, and abdomen may have their explanation for the localization in a primary muscle damage accompanied by hemorrhage and followed by an infection of variable type. Cole also comments upon the development of abscess in the deep muscles where degeneration had taken place. In illustrating some of our findings to Dr. J. Anderson he immediately recognized such a condition in the pectoral muscles of a patient in which he was unable to arrive at a conclusion of the pathological events which had taken place. It is one of the noteworthy features in this disease that the voluntary muscles of certain regions are apt to suffer severe damage, while the heart and the various unstriped muscular tissues are little if at all affected by a similar process. It would be interesting to know whether the lack of response and the delayed functional recovery on the part of the muscles of the extremities in so many patients who have suffered influenza is the result of the damaging influence of a peculiar intoxication present in this disease. One of the features in influenza is the prostration of the patient, and with it there is definite muscular weakness. We have been
