Phyllodes Tumor of the Prostate With Epithelial Intestinal Metaplasia

Am J Surg Pathol. 2018 Jun;42(6):836-839. doi: 10.1097/PAS.0000000000001052.


Phyllodes tumor of the prostate is a rare mesenchymal tumor conventionally regarded as a stromal tumor of undetermined malignant potential. While the initial presentation is that of urinary obstruction and/or hematuria, the subsequent clinical behavior is thought to be a function of stromal cellularity and cytologic changes of malignancy. Of histologic interest, the epithelial component of this tumor varies, including intestinal metaplasia, as seen in the present case.
