“…Although a malignant tumor arising in mullerianosis of the urinary bladder was still not described, one can suppose that such possibility can occur in analogy with malignization of endometriosis. A single case of endometrioid carcinoma in endometriosis of the urinary bladder [1] and four cases of clear cell carcinoma associated with endometriosis or mullerian cysts [5] were described till now. The carcinomatous epithelium in these cases was distinguishable by its malignant nuclear features, irregular gland architecture, and, at least, focal stromal desmoplastic reaction.…”

“…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

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.

“…Only eight cases of tumor arising from foci of bladder endometriosis have been reported so far in the English literature [157][158][159][160][161][162][163][164]. It should be considered that although specific criteria have been established to define the development of a malignant tumor from endometriosis [165], not all the reports on this topic seemed to have strictly followed these criteria.…”

Glandular lesions of the urinary bladder:clinical significance and differential diagnosis

et al. 2010

View full text Add to dashboard Cite

A variety of glandular or pseudoglandular lesions may be seen in the urinary bladder, ranging from those that are entirely benign to aggressive-behaving malignant primary and secondary tumours. Lesions with minimal to no evident premalignant potential include several proliferative and reactive processes, such as cystitis cystica and cystitis glandularis, although the possibility exists for confusion of such lesions with an infiltrative neoplasm, particularly in limited biopsy specimens. Similarly, ectopic tissues of Müllerian origin may be seen occasionally in the urinary bladder and their differentiation from a true glandular neoplasm is important to avoid improper treatment. As urothelial carcinoma has a propensity for divergent differentiation, a wide spectrum of morphological variants exists with varying degrees of glandular differentiation. Some such variants have demonstrated clinical behaviour that is more aggressive than their histology would suggest, thus deserving recognition and potentially different treatment. In this paper, we review the glandular lesions of the urinary bladder ranging from benign proliferative processes to malignant primary and secondary neoplasms, with emphasis on clinical significance and features useful in resolving their differential diagnoses.

Malignant transformation in endometriosis of the urinary bladder

Abstract: A case of primary intravesical endometrioid carcinoma is described, together with a review of the literature. This represents the fourth reported case of malignant transformation in vesical endometriosis.
