Yes indeed I would also consider this to be gynaecomastia,
It just depends on what stage / severity the process is at.
In the early stages you get the tree root hypo echoic changes and as it becomes more severe the echogenic glandular tissue appears.
I am recording a part 2 of the breast webinar which will deal with the male breast and other topics like implants etc.
I hope you will enjoy it when it becomes available.
Happy Easter,
Steve
