The diagnosis of @entity263 is usually made on needle biopsies. Numerous benign lesions may mimic @entity5 , especially when the focus of @entity189 is limited. The presence of seminal vesicle-ejaculatory duct epithelium on prostate biopsy is not rare and could cause @entity911 with @entity420 . Lipochrome pigments are frequently encountered in seminal vesicle-ejaculatory duct but may be also seen in @entity263 . @entity1486 immunostaining in difficult cases is sometimes used, but high-grade @entity420 may be negative. In one previous report, @entity21826 was found to be expressed in seminal vesicle but not in normal prostate. @entity21826 belongs to the family of @entity1 @entity3558 genes. So we investigated herein the immunohistochemical expression of @entity21826 in prostate @entity420 and seminal vesicle-ejaculatory duct. We have tested 30 prostate @entity420 of various grade, 10 normal seminal vesicles, and 10 prostate @entity420 invading the seminal vesicles. The tissues were fixed in 10% buffered @entity406 and embedded in paraffin. Immunohistochemistry was performed using the avidin- @entity1885 -peroxidase complex technique. All @entity420 and normal prostate structures tested were negative. In contrast, all seminal vesicles were diffusely immunostained with @entity21826 antibody. We concluded that @entity21826 is a valuable marker of seminal vesicle-ejaculatory duct and is useful for the differential diagnosis with @entity263 .
