We read with interest the significance of the different types of seminal vesicle invasion described in the recent paper by Kristiansen et al 1 The three types of invasion of the seminal vesicle are well recognised, but there is a much rarer method of invasion, that is by intraductal cancer spreading up into the seminal vesicles via the ejaculatory ducts. This method has been reported in a single case report 2 but was not seen in the series by Kristiansen 1. This article is protected by copyright. All rights reserved.
