Carcinomas arising from organs neighbouring the ureter can directly infiltrate the ureter. Distant ureteral metastasis from colon adenocarcinoma is extremely rare and usually an incidental finding in performed autopsies. We report a case of a right ureteral metastasis in a 65-year-old Caucasian male with a history of rectal cancer for which he had been treated 4 years before. He presented with asymptomatic moderate right hydronephrosis. The patient underwent a right nephroureterectomy. Histology of the ureter revealed transmural adenocarcinoma with infiltration of the mucosa. Infiltration of the muscular coat of the bladder was found 2 years later. Thus, cystectomy and left ureterocutaneostomy were performed. The patient died 6 months later due to toxic megacolon during chemotherapy. The differential diagnosis of ureteral adenocarcinoma, especially in patients with previous history of colon adenocarcinoma, should include the possibility of distant metastasis from the primary colonic tumor.


The author, while dissecting a gravid uterus of seven months, on the 8th of April, 1838, observed the trunk of a large nerve proceeding upwards from the cervix to the body of that organ along with the right uterine vein, and sending off branches to the posterior surface of the uterus; some of which accompanied the vein, and others appeared to be inserted into the peritoneum. A broad band, resembling a plexus of nerves, was seen extending across the posterior surface of the uterus, and covering the nerve about midway from the fundus to the cervix. On the left side, a large plexus of nerves was seen, surrounding the uterine veins at the place where they were about to enter the hypogastric vein. From this plexus three large trunks of nerves were seen accompanying the uterine vein, which increased in size as they ascended to the fundus uteri. From the nerve situated on the posterior surface of the vein, numerous filaments passed off towards the mesial line, as on the right side; some following the smaller veins on the posterior surface of the uterus, and others becoming intimately adherent to the peritoneum. The largest of the nerves which accompanied the uterine vein was traced as high as the part where the Fallopian tube enters the uterus; and there it divided into numerous filaments, which plunged deep into the muscular coat of the uterus along with the vein. A large fasciculated band, like a plexus of nerves, was also seen on the left side under the peritoneum, crossing the body of the uterus; and several branches, apparently nervous, proceeding from this band, were distinctly continuous with some of the smaller branches of nerves accompanying the uterine veins. The preparation of the parts was placed in the Museum of St. George’s Hospital, on the 1st of October, 1838; and several anatomists who examined it were of opinion that they were absorbents accompanying the uterine veins, and tendinous fibres spread across the posterior surface. Dr. Lee availed himself of another opportunity which presented itself, on the 18th of December of the same year, of examining a gravid uterus in the sixth month of pregnancy, which had the spermatic, hypogastric and sacral nerves remaining connected with it; and during the last ten months, he has been diligently occupied in tracing the nerves of this uterus. He believes that he has ascertained that the principal trunks of the hypogastric nerves accompany, not the arteries of the uterus, as all anatomists have represented, but the veins; that these nerves become greatly enlarged during pregnancy; and that their branches are actually incorporated, or coalesce with the branches of the four great fasciculated bands on the anterior and posterior surface of the uterus, bearing a striking resemblance to ganglionic plexuses of nerves, and sending numerous branches to the muscular coat of the uterus.

This is Part I., of a series of three, of a paper on the microscopical characters of rhythmically contractile muscular tissue, other than that of the blood-heart. It comprises a reexamination of the microscopical characters of the rhythmically contractile muscular coat of the veins of the bat’s wing, and is offered by the author as Appendix No. 3 to his paper in the Philosophical Transactions for 1852, entitled “Discovery that the veins of the Bat’s Wing (which are furnished with valves) are endowed with rhythmical contractility, and that the onward flow of the blood is accelerated by each contraction.” This reexamination supplies additional details, illustrated by more correct figures, confirmatory of the author’s previous description of the microscopical characters of the muscular coat of the veins of the bat’s wing. The author examines also, by way of comparison, the tonically contractile muscular coat of the arteries, and points out that, though the fibrils of the muscular coat of the veins do not present transverse markings, they differ in their microscopical characters as much from the fibrils of the muscular coat of the arteries, as the transversely striped muscular fibrils of the bat’s heart do from them. He insists, therefore, in conclusion, that there are no grounds for an implied physiological form of the doctrine of isomerism, viz. similarity of structure, with different endowments.

The paper consists of two parts, having a real relation to each other, though apparently little connected. I. On the Movements of the Stomach .—The anatomy of its muscular coat is first briefly mentioned, and the so-called oblique fibres of some authors stated to be really transverse, i. e . at right angles to the altered direction of the canal. The muscular actions of the digesting stomach are then considered.
