The etiology of EAF is unknown. ⋯ The 19-year-old woman is the youngest patient with EAF ever described.

To investigate the incidence of amyloidosis of seminal vesicles and ejaculatory system including ejaculatory ducts and vasa deferentia, we reviewed the whole mount sections of 447 radical prostatectomy specimens removed for prostatic cancer, including 273 cases from the United States and 174 cases from Korea. Of these, 21 cases (4.7%) showed amyloidosis in seminal vesicles, vasa deferentia, and in ejaculatory ducts. Ten of these (3.7%) cases were from the United States and 11 cases (6.3%) from Korea. ⋯ The vessels or prostatic stroma are not part of this process. Amyloidosis develops subepithelially spreading to include the wall of these organs and appears to be related to advanced age. The incidence of amyloidosis of the ejaculatory system in Korean patients was higher than in US patients.
