Short Case Report
Leiomyosarcoma of the Prostate A 63-year-old man presented with frequency and hesitancy of micturition for 3 months. He never had any acute retention of urine. Physical examination revealed a non-tender distended urinary bladder and a smooth softish non-tender mass continuous with the left lobe of the prostate. The median groove of the prostate was palpable, and its right lobe was within normal limits. Serum alkaline and acid phosphatase and blood urea were within normal limits. An intravenous pyelogram showed normal excretion with calyceal system and ureters looking normal. The urinary bladder was displaced to the right by external pressure (see Fig. 1). Suprapubic exploration on 3rd April 1973 revealed a mass arising from the pelvis with apparent continuity with the left side of the bladder wall. The bladder was opened and mucosa found intact. Careful dissection showed the tumour to be extra-vesical, and arising from the left lobe of the prostate. The removed tumour was found to be encapsulated except at its attachment to the prostate, and measured 12 cm x I I cm x 7 cm. Histology showed highly cellular tissue and fibroblasts and muscle fibre consistent with the diagnosis of leiomyosarcoma (See Fig. 2). At his last follow-up on 28th July 1974 he was well, with no sign of recurrence.
Comment
Leiomyosarcoma of the prostate is rare, constituting 0.1 % of prostatic malignancies (Stirling and Ash, 1939). Few patients survive for more than 7 months after diagnosis (Longley, 1955). AMLCHANDRA CHAYTERJEE Goa Medical College, Panaji,Goa, India
