Primitive neuroectodermal tumor of the prostate in a 64 years old man: An unusually late presentation

Abstract

Primitive neuroectodermal tumors (PNETs) are uncommon tumors that primarily affect young males. They are rarely seen in the prostate and occurence in an old age group is uncommon. We present a case of a 64-year-old male who presented with complaints of difficulty in passing urine for 1-year duration and on contrast-enhanced computed tomography showed an enlarged mass in the prostate with hypoattenuating areas. Serum prostatic specific antigen was mildly raised. Transurethral resection of prostate was done and histology showed clusters of round cells that expressed CD99. The patient underwent radical surgery for tumor resection. PNETs are tumors of soft tissue origin and generally affect the young age group. This case of PNET in the prostate is unusual for its site and age of presentation. In conclusion, while making a diverse diagnostic evaluation of aggressive prostate cancers, PNET should be taken into account.
