CLINICAL PRESENTATION A 56-year-old Chinese male with previously diagnosed prostatic stromal tumour of uncertain malignant potential (STUMP) presented with urinary retention 6 years after transurethral resection of prostate (TURP). TREATMENT AND OUTCOME Cystoscopy showed a papillary tumour of the prostatic urethra causing near-complete obstruction. Repeat TURP was performed. He has been asymptomatic since. CONCLUSION There has been fewer than 100 cases of this lesion reported worldwide. Definitive treatment is not well established. Longterm follow-up to monitor progression and possible recurrence is required, and repeat TURP or radical surgery may be necessary.
