Urology/soft enlargement on the



I have a soft lump on  my penis. It is located on the middle vein on the top of the shaft of my penis just below the stomach. It is soft ,painless, 1 cm in width, squeezable, visible when the penis is flaccid or erect. slight widening of the vein on the penis shaft is evident also.
I can recall it has been there for  almost 2 years.
Could you please help me with a possible diagnosis.


A reliable diagnosis is obviously not possible from just your description.  It could be a vascular issue as it is located in the large vein along the top of the penis.  If so, it would not usually be something that we would treat and the fact that it's been there for 2 years suggests that it isn't anything particularly dangerous.  It may be best to consult with a local urologist just to be sure.

QUESTION: Thanks you dr. For your reply.
I attached pictures of the lump.
If you may have a look at it.

ANSWER: Samir:

Looks like a venous bleb or dilation of a large, superficial vein.  If so, it's harmless.

QUESTION: Dear dr,
Is there a  possibility that it will  increase by time and What could have caused it.
I also have varicocele. Any relation?

Thx again


Remember, we are uncertain as to the actual diagnosis.

The bleb may increase with time, or it may not.

Cause is usually developmental meaning it was always there but becomes more prominent with age.

Not related in any way to a varicocele.
