Eczema is much more common in childhood compared with psoriasis. The inner elbow area or flexural area is also a more common site for atopic eczema. Psoriasis tends to affect more the extensors of the elbow and the onset is often in the later teens and twenties, although it can also occur in childhood.
The diagnosis of psoriasis and eczema is usually made clinically. If you have any doubts, you can visit your doctor or dermatologist, who can give you a proper assessment of the rash.
