Abstract
Specialized stromal tumours of prostate includes stromal tumors of uncertain malignant potential
(STUMP) and stromal sarcoma. Florid Benign prostatic hyperplasia must be differentiated from
prostatic stromal neoplasia. Prostatic STUMPs may have significant overlap with florid stromal
hyperplasia. A case of prostatic STUMP is reported in this article. A 56 years old man presented
with dysuria. Ultrasonography and CT scan showed inhomogenous parenchyma and highly
suspicious lesion in posterior transition zone and postero-lateral peripheral zone of left lobe at mid
gland of prostate. Capsular invasion was absent. Core biopsy revealed nodular hyperplasia with
focal phyllodes like atypical stromal hyperplasia (STUMP). PSA level was 7.2 ng/ml. We should
observe the glandular epithelial neoplasia and stromal cells changes during histopathological
diagnosis because sarcomatouus changes in stromal cells is equally devastating as carcinoma
