I am a healthy 33 year old female. I noticed a small marble sized lump on the top of my forearm under the skin last night. It does not move, is extremely painful and I have some tingling in the arm. There is no visible bruising, and I do not remeber any trama. Could this be a malignancy?

That's always a possibility, but there are also a lot of other things it could be. There are a lot of causes of lumps and bumps in the hand and forearm.

These can include: ganglion cysts, epidermal inclusion cyst (EIC), foreign body granuloma, fibroma, neuroma, local abscess, sebacous cyst, and many more.

The only way to know for sure, is to have it looked at by your physician. If necessary a biopsy can be done.

Good luck.
