Abstract

Malakoplakia is an inflammatory process that has been rarely reported in the prostate. Malakoplakia in association with prostatic carcinoma is exceedingly rare with only 4 previously reported cases. We describe the clinical features and the associated pathology in 4 patients who demonstrated malakoplakia of the prostate in association with prostatic adenocarcinoma. Prostatic malakoplakia presenting in association with prostatic adenocarcinoma was identified in 4 patients through a search from the records of 3 institutional databases with large in-house and consult uropathology practices. In 2 of the patients the diagnostic needle biopsy contained only prostatic carcinoma; malakoplakia in association with prostatic carcinoma was documented on prostatectomy, performed 15 and 8weeks after the biopsy, respectively. Both patients experienced urinary infections during the interval between the biopsy and the prostatectomy. The third and fourth patient had a long-standing history of “prostatitis”, and acute urinary tract infection with urinary retention, respectively. The needle biopsy in both patients showed concomitant malakoplakia and prostatic carcinoma. One of them also had malakoplakia on the initial biopsy containing only atypical glands and on the subsequent one demonstrating carcinoma. One patient was treated conservatively and one with prostatectomy. Although coexistent prostatic carcinoma and malakoplakia are exceedingly rare, malakoplakia can likely occur as an exceptionally rare complication of a prostate needle biopsy, particularly in individuals with long-term or acute urinary tract infections at the time of the biopsy.

Our First Participant!

Thanks to the participation from men with suspected prostate cancer and men diagnosed with prostate cancer, we will be able to measure if our “tests” can reveal the true nature of prostate cancer and if the tests or biomarkers can diagnose prostate cancer and tell us what cancers are more aggressive.

As part of the Alberta Prostate Registry and Biorepository, patients will be entered into our study, in which blood and other samples are collected over time and their health outcomes are recorded over many years. Patients will follow standard medical advice and care through their doctors. Our team collect biospecimens and information related to general health and cancer behavior over time.

Rather than being frightened by the word ‘cancer’, we want to learn how to predict serious and morbid prostate cancer complications well before they happen, so that we can weigh carefully the pros and cons of available treatments.

In the process, we expect to identify new and important advantage points for better therapies to be developed. The word “cancer” may be scary, but what is truly scary is unawareness.

“It makes me very happy to be able to contribute to find better ways to diagnose prostate cancer.”
