Urology/white lump on my penis shaft when erect


little white lump
little white lump  
I've noticed white oval lump on my penis shaft when it's erect, it doesn't move and quite solid, like a small pear, it disappears when my reaction it's gone, do you know what it might be and how to cure it?


It's obviously hard to determine reliably what various lumps and lesions are on the penis.  However, a small, painless, soft white nodule in this location is often a small sebaceous cyst.  If it doesn't hurt or bother you, we often recommend that such cysts be left alone but it can be removed with a small surgery if you wish.

Have this checked by your local physician to be sure.
