Abstract
PDF - A sarcomatoid variant of urothelial carcinoma in the female urethral diverticulum has not been reported previously. A 66-year-old woman suffering from dysuria presented with a huge urethral mass invading the urinary bladder and vagina. Histopathological examination of the resected specimen revealed predominantly undifferentiated pleomorphic sarcoma with sclerosis. Only a small portion of conventional urothelial carcinoma was identified around the urethral diverticulum, which contained glandular epithelium and villous adenoma. The patient showed rapid systemic recurrence and resistance to immune checkpoint inhibitor therapy despite high expression of programmed cell death ligand-1. We report the first case of urethral diverticular carcinoma with sarcomatoid features.

Abstract

- We reviewed 2159 consecutive cases of surgically resected appendices. The appendectomy specimen consisted of 91 cases of acute focal appendicitis (5.4%), 926 cases of acute suppurative appendicitis (55.1%), 228 cases of acute gangrenous appendicitis (13.6%), 63 cases of periappendicitis (3.8%), 13 cases of pure fibrous obliteration of the lumen (FOL; 0.8%), 18 cases of other diseases (7 mucoceles, 2 mucinous cystic neoplasms, 4 carcinoids, 2 metastatic carcinomas, 2 tuberculous appendicitides, and 1 eosinophilic appendicitis; 1%), and 342 cases with no diagnostic abnormality (20.3%). Patients having acute appendicitis ranged from 3 to 84 years of age, and patients in their 10's and 20's occupied over half of 2159 cases. Diagnostic accuracy of the acute appendicitis was 79.7%. Incidence of the acute appendicitis was suspected to be 7.2/100,000/year. Twenty eight cases of acute appendicitis were associated with diverticula. In the former acute primary diverticulitis led to acute appendicitis in 14 of 28 cases. Among 478 incidental appendectomy cases, there were 3 acute focal appendicitides, 1 acute suppurative appendicitis, 1 eosinophilic appendicitis, 32 periappendicitides, 1 mucocele, 40 pure FOLs, 1 deciduosis, 1 endometriosis, and 1 diverticulosis without inflammation. There were 69 cases of FOL (32 complete forms and 37 incomplete forms), among which 13 cases were associated with acute appendicitis. FOL was more frequent in female patients as well as patients over 40 years of age. Incomplete FOL was considered to progress to complete form with age. The incidence of appendiceal diverticula was higher, whereas the incidences of carcinoid tumor and FOL were lower compared with that in the western report. In 14 of 28 cases the appendiceal diverticulum was the site in which acute appendicitis began.

Abstract
PDF
- The morphologic development of the liver in the embryonic period is described in serial sections of 18 human embryos representative of Horizons 12 to 23 . In the earliest specimen of horizon 12, the liver is seen as branching cord of endodermal cells originating from the hepatic diverticulum and invading into the loose stroma of septum transversum, transforming the surrounding stromal cells into primitive blood spaces and blood cells. Thereafter, the parenchymal cells rapidly proliferated so that the size of the organ was reaching a fifth of the CR length in horizon 23. The vascular system of the liver was in a symmetric configuration in horizon 12, which is composed of umbilical and vitelline veins and hepatocardiac channels on both sides. The evolution of the vascular system includes intergration of the vitelline veins into the portal vein, obliteration of the right umbilical vein and left hepatocardiac channel, and creation of the ductus venosus. The intrahepatic biliary tract is found to be formed by the "in situ transformation" mechanism, which involves transformation of the parenchymal cells, adjacent to the fibrous tissue surrounding the portal and umbilical veins, to networks of cuboidal epithelial cells lining the ductal lumen. These intrahepatic duct systems were found to communicate with the extrahepatic system at the porta hepatis.
