Sarcomatoid Carcinoma of Prostate: Report of an Unusual Tumor

Prostatic sarcomatoid carcinoma (SC) is an extremely rare type of malignant tumor of prostate. A 57 years old man presented to the outpatient department with lower urinary tract symptoms and altered bowel habits. Clinical assessment revealed a stony hard prostate with normal serum prostate specific antigen (PSA). Histopathology of the prostatic biopsy revealed spindle cell tumor with brisk mitosis. Immunohistochemistry showed positivity with cytokeratin and vimentin in these cells, an uncommon finding, clinching the diagnosis of SC.
