The mutational frequency of BRAF and KRAS in low-grade serous testicular neoplasms-a case series.

Aims: Low-grade serous neoplasms of the testis are rare neoplasms that show striking morphological similarities with the better-understood ovarian neoplasms. This study is to see if there are similar molecular abnormalities in these two tumours. The cell of origin, relationship with serous ovarian tumour and the pathogenesis of these neoplasms are not fully established.

Intraductal spread of prostate cancer into the seminal vesicles.

We read with interest the significance of the different types of seminal vesicle invasion described in the recent paper by Kristiansen et al 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 but was not seen in the series by Kristiansen . This article is protected by copyright.
