Myself Dr Josh- A Board Certified Physician and I’m happy to help with your question today.

Well, Such pea size lump in his armpit could be- Epidermoid Cyst.

They grow slowly and don't usually cause any problems. He may want to remove it if it doesn't look good, or if it's painful, infected or ruptured.

Such cyst are round lumps and can be felt just beneath the skin surface. They are very common. Usually they are small of the pea size but sometimes they slowly get bigger over many months to become a few centimeters in diameter. No need to worry for that.

Regarding bony growth on skull could be related with collection of fibrous tissue with core bony material attached to his skull. One more possibility is sebaceous or epidermal cyst.

To be honest, I would not be worried for any serious issue.

This can be left alone.

For peace of mind, you can get a clinical examination done by doctor.

Hope this helped

His bone tumor was called Osteochondroma
Expert:  Dr Josh replied 3 months ago.


Well, An osteochondroma is a benign (noncancerous) tumor and it usually develops during childhood or adolescence.

And in most cases of osteochondroma, no treatment is required other than regular monitoring of the tumor to identify any changes or complications

An x-ray would show the bony growth of an osteochondroma.

As, skull x-ray has already been done, so i would not panic for any serious issue. Yes, such lump, is felt as hard and without pain.

It is not indicative of any serious issue. No need to worry.

For peace of mind, you can get a clinical examination done by doctor.

Hope this helped
