The duodenum shows often intense congestion. This occurs with sufficient frequency to demand attention, especially as a similar condition has been described in other disorders grouped with scurvy. Willcox and others found congestion of the duodenum and of the lower intestine in beriberi, and Andrews described not only congestion but even minute hemorrhages. Small duodenal ulcers are by no means infrequent both in human and in guinea-pig scurvy (Holst and Froelich). The presence of such marked congestion surrounding the papilla of Vater would lead us to expect the occurrence of catarrhal jaundice associated with scurvy. But, on the contrary, icterus has rarely been noted in scurvy. Urizio has described jaundice in this connection, but it is difficult to decide whether his cases were true scurvy, as they occurred in an epidemic of jaundice and no histologic examination of the bones was carried out.
The intestine may present a variety of lesions.[29] The mucosa is frequently congested and swollen, and the solitary follicles and Peyer’s patches enlarged. These changes may progress to necrosis and extensive ulceration. In an outbreak of scurvy occurring in this country in 1917, in a large institution for epileptics, ulceration was a frequent lesion at necropsy.[30] Dysentery, a frequent complication of scurvy in some epidemics, may add to this ulceration and lead to even complete sloughing of the inner lining of the intestine. Hemorrhages are found in the mucous, serous or muscular layers. Here, as elsewhere, the hemorrhages vary in size from petechiæ to large infiltrations of blood. A very striking picture is sometimes presented by the pale, edematous intestinal wall dotted or streaked with vivid red.
Liver.—The liver is frequently congested, as would be expected in view of the involvement of the right heart. Erdheim found congestion, however, in only nine among thirty-one necropsies, although enlargement of the heart was present twenty-one times. There may be hemorrhages in the glandular tissue or under the peritoneum. “Cloudy” and fatty degenerations occur occasionally, and in some cases an early cirrhosis. Lind found abscess of the liver, and wrote that in a few instances “the matter or corruption was hardened, as it were, into a stone.”
Spleen.—This organ is usually somewhat enlarged and congested. Charpentier, in the Paris epidemic of 1871, found it often three to four times the normal size and very soft, and Lind tells us that “the spleen was three times bigger than natural, and fell to pieces, as if composed of congealed blood.” It must be remembered that the pathologic as well as the clinical picture of the scurvy of Lind and his time was generally complicated by infection. The enlargement is usually by no means so great, and no doubt is due in part to intercurrent infections. On section, it is found frequently to contain much reddish-brown pigment. Hemorrhage may also occur. In beriberi, Andrews observed frequent congestion of the spleen and also a loss of normal markings.
Pancreas.—There is but one reference to a lesion of the pancreas in scurvy, that of Sato and Nambu, who encountered hemorrhage of this organ in one case among the necropsies performed in the course of the Russo-Japanese War.
Kidneys.—Here again, congestion and hemorrhage are the two lesions most commonly found. The kidneys also may show any of the forms of nephropathy ordinarily recognized, but these must be regarded as complicating conditions and not a part of the true scurvy.
Small hemorrhages may be found in the uterus, bladder or urethra. They are especially common in the bladder, both in man and in the guinea-pig, and in some instances may be the cause of the hæmaturia noted during life.
Lymph-nodes.—General enlargement of the lymph-nodes has been described, but occurs probably only in advanced cases where a general infection has been superadded. As a rule the enlargement is confined to nodes draining areas where hemorrhage has occurred. On section these nodes are reddish or brownish as the result of the pigment which they contain, the “black and red spots of different sizes” mentioned by Lind. Following infection they may become purulent, resulting in the inguinal buboes so frequently mentioned by the older authors,[31] or in the purulent mesenteric nodes associated with intestinal ulceration.
Organs of Internal Secretion.—Until recently these organs have received but little attention. It is probable, however, that in the near future they will be the object of close study and that new information will be acquired as to their condition in this disorder. Hemorrhages are commonly seen in the adrenals, enlarging them greatly and giving them a deep red color; the hemorrhage generally involves mainly the medullary portion.[32] It is probable that careful scrutiny will disclose hemorrhages in the other glands of internal secretion. The question of the involvement of these glands will be again considered under the microscopic anatomy, and has been taken up from a functional standpoint in treating of the possible indirect action of the vitamines.
The brain and the spinal cord likewise have been but little studied. It is hardly to be expected that much will be learned from an investigation of the gross pathology of these organs, but the microscopic anatomy offers a promising field of research. Hemorrhage may occur into the brain substance, into the cord or the membranes surrounding them. Pachymeningitis hemorrhagica interna has been described frequently (Meyer, Hayem, Sutherland, Sato and Nambu) and may give rise to the symptoms of meningitis. Sutherland reports an instance where thrombosis of the basal artery was found postmortem. In one case, that of Feigenbaum, hemorrhage of the cord was diagnosed during life and confirmed at necropsy.
