Lower Urinary Tract Symptoms Due to Xanthoma of the Prostate After Kidney Transplantation: A Case Report.

Transplant Proc 2020 Nov 15;52(9):2736-2738. Epub 2020 May 15.

Departments of Anatomic Pathology and Urology, School of Medical Sciences, State University of Campinas (Unicamp), Campinas, Brazil.

Background: Prostatic xanthoma is a lesion of unknown cause that is often an incidental finding in patients undergoing needle biopsy or transurethral resection. To the best of our knowledge, we report on a unique case of a pure xanthoma without benign prostatic hyperplasia of the prostate in a patient with lower urinary tract symptoms manifested after kidney transplantation.

Methods: A 62-year-old man was submitted for a kidney transplant in April 2018. Read More

Dramatic Enlargement of the Prostate due to Xanthogranulomatous Inflammation.

Low Urin Tract Symptoms 2015 Sep 14;7(3):166-8. Epub 2014 Aug 14.

Department of Urology, NYU Langone Medical Center, New York, New York, USA.

Case: Xanthogranulomatous inflammation of the prostate is a rare condition that can cause lower urinary tract symptoms and may be mistaken for adenocarcinoma. It is often seen on prostate biopsy, but can usually be treated conservatively with temporary catheterization, alpha blockade, and allowing time for improvement. We present a case of a 78-year-old man found to have a 318 g prostate secondary to xanthogranulomatous inflammation. Read More

Best practices recommendations in the application of immunohistochemistry in the prostate: report from the International Society of Urologic Pathology consensus conference.

Am J Surg Pathol 2014 Aug;38(8):e6-e19

*Departments of Pathology, Urology, and Oncology, The John Hopkins Medical Institutions, Baltimore, MD ‡Department of Pathology, Yale University School of Medicine, New Haven, CT †Department of Oncology-Pathology, Karolinska Institutet, Karolinska University Hospital, Stockholm, Sweden §Section of Pathological Anatomy, Polytechnic University of the Marche Region, School of Medicine, United Hospitals, Ancona, Italy.

The following are the International Society of Urological Pathology (ISUP) recommendations for the use of immunohistochemistry (IHC) in prostate specimens. Either high-molecular weight cytokeratin (34βE12 or CK5/6 or others) or p63 or a combination of the 2 with AMACR either in a double or triple cocktail is recommended for the workup of small foci of atypical glands suspicious for adenocarcinoma of the prostate (PCa). ERG is optional as it is present in only 40% to 50% of prostate cancers and also positive in high-grade prostatic intraepithelial neoplasia. Read More

[Pseudohyperplastic carcinoma with xanthomatous changes: a neoplasm mimicking glandular hyperplasia of the prostate].

Actas Urol Esp 2010 Apr;34(4):333-9

Departamento de Patología, Instituto Nacional de Ciencias Médica y Nutrición Salvador Zubirán, Ciudad de México, México.

Introduction And Objectives: Varieties of prostatic adenocarcinoma whose architectural and cytological appearance mimicked benign lesions have been reported in recent decades. Such neoplasms include xanthomatous (foamy) carcinoma and pseudohyperplastic carcinoma. We recently studied five carcinomas showing a cytoarchitectural combination of both neoplasms which were confused with benign glandular proliferations. Read More

prostatic xanthoma: a mimic of prostatic adenocarcinoma.

Hum Pathol 1994 Apr;25(4):386-9

Department of Pathology, Mayo Clinic, Rochester, MN 55905.

Xanthoma is a localized collection of cholesterol-laden histiocytes that is usually idiopathic, but may be seen in patients with hyperlipidemia. We report seven cases of xanthoma involving the prostate, including one arising in a patient with mild hyperlipidemia. Prostatic xanthoma appeared as a solitary microscopic lesion in the peripheral zone (six cases) or transition zone (one case). Read More
