“…Muzinhaltige Zellen im Epithel der Blase werden fur das Schwein nicht nur im Falle einer Zystitis beschrieben (ZOCH, 1964;TOO et al, 1985), sondern auch bei der exsudativen Dermatitis und im Zusammenhang mit Fallen von E.-coli-Enteritis, Schweinepest und suppurativer Arthritis (MEBUS et al, 1968;BROBST et al, 1971). Auch bei Menschen, Rindern und Katzen wurde iiber ahnliche Alterationen am Ubergangsepithel oder der Lurninu propria des Harntraktes bei chronischen Iniektionen als Cystitis cystica oder Cystitis glandularis berichtet (KRAG und ALCOTT, 1957;BROBST und OLSON, 1963;ZACHARY, 1981;WALTHER et al, 1987;BARRESI und MARAFIOTI, 1990;NEW und ROBERTS, 1990;NODA und ETO, 1990).

Study of Eubacterium-suis Infection in the Bladder of Sow using ElectronmicroscopyScanning electron microscopy was performed on bladder biopsies from 20 sows with cystitis. Results were compared with those of healthy control animals. Biopsy specimens were taken from nine sows infected only with commensal bacteria (E. coli, streptococci, staphylococci) and from 11 sows, where Eubacterium suis (E. su25) was involved in urinary tract infection and had caused a haemorrhagic cystitis. Increased losses of normal superficial cells covered with microplicae could be seen depending on the degree of cystitis. Desquamation of the surface layer exposed smaller cells patterned with short microvilli. These cells were presumed to be immature intermediate cells and goblet cells. Goblet cells were found only in infected organs. The varying surface structure of epithelial cells in relation to receptor quality is important for the bacterial adherence to bladder mucosa.All examined bladders infected with E. suis showed a total loss of superficial cells. Luminal cells covered with multiple short microvilli were accompanied by cells with long pleomorphic processes. Accumulating cell necrosis was indicated by a smooth surface structure. Funnelshaped orifices between the epithelial cells were identified as excretory ducts of mucus-filled cysts, which are formed by the confluence of degenerating goblet cells.E. suis infection of the porcine bladder causes more severe alterations than infections due to other bacteria. However, debilitation of the urothelium due to previous infection is necessary to support infection of the bladder with E. suis.

“…The lesion occurs in female patients of reproductive age, and its pathogenesis appears to be similar to that of ordinary endometriosis [1][2][3][4]6]. In this paper, we would like to describe an additional case, in which an unusual association with glandular cystitis of intestinal type was observed besides the typical clinicopathological features.…”

Mullerianosis of the urinary bladder: report of a case with suggested metaplastic origin

et al. 2006

View full text Add to dashboard Cite

Mullerianosis of the urinary bladder is a very rare and morphologically complex tumor-like lesion. It is composed of several types of mullerian-type lesions, including endometriosis, endocervicosis, and endosalpingiosis. This disease occurs in women of the reproductive age group. In the pathogenesis, implantative and metaplastic origins have been suggested, and they are still under discussion. In the present report, a rare case of this lesion in a 41-year-old woman is described. The bladder contained, in addition to typical mullerianosis, glandular cystitis with focal intestinal metaplasia. An interesting and, to our knowledge, hitherto unreported feature was a rare continuity between the glands of mullerianosis and glands of glandular cystitis. The histologic and immunohistochemical findings in the present case support strongly the metaplastic origin of mullerianosis.
