Brief Answer:
Acne nodule

Detailed Answer:

As I mentioned before this is an acne nodule.

Ideally I would have treated it by injection of a triamcinolone acetonide (a steroid) in a concentration of 2.5 mg/ ml, 2-4 units, with a 26 G needle. Thereafter, it would settle down within 48 hours.

I would suggest that you take him to a dermatologist who would administer it. The steroid has to injected into the nodule. The procedure is simple and there is only a minor pain.
