A case of fistulizated pelvic malacoplakia: cytohistologic, immunohistochemical and electron-microscopic study.
A case of malacoplakia with a tumor-like involvement of the pelvis is presented. It was characterized by a urine-trickling fistula from the bladder to the gluteal surface and by acute urinary retention. Examinations both cytologic of urine collected from urethra and from fistula, and histological of tissues from bladder and rectum were performed. Histiocytes with Michaelis Gutmann bodies were found in all specimens. The specimens were also studied from an immunohistochemical and electron-microscopic point of view. The case was found interesting because of the unusual fistulization and for the absence of other important associated diseases usually reported in the literature.
