Customer Question

I have a lump on my left shoulder. It doesn't hurt. It is about 1cm. It doesn't have a distinct shape. It seems like it is sitting on the bone. I am 54.

Hello. I'm Dr. Phil, licensed and practicing internist. Excellent service is my goal.

Thanks for this excellent question.

I'm sorry you are having this problem

I need to gather additional information in order to give you the best answer possible

Where exactly on the shoulder?

Is it soft or hard?
Customer: replied 3 years ago.

it is on the top of the round bone, directly above the armpit on on the very top of the shoulder, it is hard.

Expert:  Dr. Phil, MD replied 3 years ago.
thank you for that reply Helen

this is most likely a ganglion cyst.

This is a cyst related to a joint. These are quite common and occur when part of the joint capsule pushes out.

This is nothing to worry about

I would have it looked at to be sure. Even if its not a ganglion cyst I'm quite sure its not cancer or anything serious

I hope this helps. If you have more questions just reply.

Hi
I have some additional information
A ganglion cyst is possible, but it is uncommon on the shoulder. As well, they are soft- as they are fluid filled cysts.
More commonly this is osseous hypertrophy (or bony overgrowth) of the AC joint (acromioclavicular). This is not a cancer nor is it arthritis.
It is not uncommon for a mass to be over the acromioclavicular (AC) joint. This is located on top of the shoulder, at the end of the collar bone- just as you describe.

Very rarely would it be a cancer- osteochrondromas can form on the humeral head, but this is more common in young adults.

Since this is causing you concern, you should see your physician for examination and an xray. Depending on the findings, they may want to do further studies, such as a CT scan or MRI.

Hang in there and keep me posted.

please leave positive feedback if this helped.

Ganglion cysts can often be hard. Especially if they are calcified
Expert:  Dr. Natasha replied 3 years ago.
Ganglion cysts typically have a smooth rounded shape as they are a cyst. As you have described, this mass does not have any particular shape which makes it very unlikely to be a ganglion cyst. As well, they are very rare on the shoulder.

An xray will tell all. Either way- it is not likely to be dangerous! :-)
