Transrectal ultrasound appearance of squamous cell carcinoma involving the prostate.
OBJECTIVE
This report describes the transrectal ultrasound appearance of squamous cell carcinoma of the prostate.


METHODS
One case of squamous cell carcinoma involving the prostate by extension from a primary urethral carcinoma and a second case of radiation-induced primary prostatic squamous cell carcinoma are presented and the ultrasound findings discussed.


CONCLUSIONS
In these 2 cases, squamous cell carcinomas involving the prostate exhibited similar transrectal ultrasound appearances. Both lesions demonstrated an irregular, anterior, relatively hyperechoic appearance.
