Nickel itch is a dermatitis resulting from sensitization to nickel the first symptom is usually pruritis, which occurs up to 7 days before skin eruption appears. The primary skin eruption is erythematous, or follicular it may be followed by superficial discrete ulcers that discharge and become crusted or by eczema. The eruptions may spread to areas related to the activity of the primary site such as the elbow flexure, eyelids, or sides of the neck and face. In the chronic stages, pigmented or depigmented plaques may be formed. Nickel sensitivity, once acquired, is apparently not lost of 100 patients with positive patch tests to nickel, all reacted to the metal when retested 10 years later. ... 

Nickel can pose some minor health hazards to people who come into contact with it. For example, both nickel in solution and the nickel in stainless steel are known to cause a skin irritation known as nickel itch, which is a form of dermatitis. Stainless steel watches, jewelry, and glasses frames have all been known to cause this irritation. More serious health hazards can come from inhaling nickel dust. In nickel mining and other industrial environments where nickel is used, inhaling the dust has been linked to nasal and lung cancer. 

This is a hard blue-white metal used in electroplating and in a range of alloys. Nickel salts may cause skin sensitivity (nickel itch) while nickel carbonyl (a gas) may irritate the lungs (broncho-pneumonia) and has been associated with cancer of the lung.

Nickel tetracarbonyl can be absorbed through the skin. While the skin contact with a dilute solution can cause dermatitis and itching, that from a concentrated solution or the pure liquid can produce a bum. Absorption of the liquid through the skin may result in death. The subcutaneous and intravenous LD50 values in rats are 60-70 mg/kg.
