Adenomatoid metaplasia of prostatic urethra. 1981

S A Martin, and D J Santa Cruz

Adenomatoid metaplasia, or so-called nephrogenic metaplasia, is an uncommon alteration of urothelium associated with prior trauma and/or chronic infection. Although the majority of reported cases of adenomatoid metaplasia have involved the urinary bladder, two cases of patients in whom the metaplastic changes were present in tissue from prostatic resections are presented. The fact that both patients had undergone prior transurethral resections of the prostate further supports the association between adenomatoid metaplasia and trauma. Confusion of adenomatoid metaplasia with prostatic ductal carcinoma in one of the cases emphasizes the importance of the recognition of this lesion. The distinction of adenomatoid metaplasia from ductal carcinomas and from other benign proliferative lesions in the prostatic urethra is discussed.

D008679	Metaplasia	A condition in which there is a change of one adult cell type to another similar adult cell type.
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011467	Prostate	A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.	Prostates
D011468	Prostatectomy	Complete or partial surgical removal of the prostate. Three primary approaches are commonly employed: suprapubic - removal through an incision above the pubis and through the urinary bladder; retropubic - as for suprapubic but without entering the urinary bladder; and transurethral (TRANSURETHRAL RESECTION OF PROSTATE).
