Prostate cancer is a common malignancy in men; however, sarcoma of the prostate is an uncommon variant. Sarcoma of the prostate occurs in all age groups with rhabdomyosarcoma being more common in children while leiomyosarcoma occurs more in the older adults. Stromal tumour of uncertain malignant potential (STUMP) occurs in adults. Modalities of treatment include surgery, radiotherapy and chemotherapy used singly or in combination, but all report poor long term survival despite treatment selected. We present 2 cases of prostate stromal tumours.

Case report

We present two patients in their fourth decade who presented with acute urinary retention. Computed tomography scan was performed in both cases and showed a large tumour arising from the prostate. Prostate specific antigen was less than 4ng/ml in the two cases and core needle biopsy performed and samples taken for histology. The histology reports showed embryonal carcinoma and STUMP in the first and second cases respectively.


Prostate sarcomas are uncommon but may pursue aggressive clinical course while STUMP has a variable course. Early diagnosis and use of combined modalities of treatment may be required to improve survival.
