Unlikely: Leukemia or lymphoma is very low on the list of causes for itching. Dry skin is by far much more common. Try applying a moisturizer on your skin <3 minutes after bathing and perhaps again 12 hrs later (with or without bathing). Have you tried taking a sedating antihistamine to see if it helps? If problem persists, see allergist or dermatologist.

Scratching causes it: Petechiae result from a minor bleed from a broken capillary blood vessel. The most common cause for petechiae limited to a specific area is local trauma. Scratching is a common cause. If your petechiae appeared in certain areas only after you started scratching that would be a likely cause. If that is not the case or if your problem persist or worsen see your physician for a specific diagnosis.
