Intralesional corticosteroids.

Intralesional corticosteroids are commonly used in clinical dermatology. They are an adjunct to topicals and a possible substitution for systemic corticosteroids. Intralesional corticosteroids can be injected via a syringe and needle or with a Dermo-Jet. Although multiple preparations are available, the triamcinolones have more acceptable physical characteristics. Systemic absorption and consequent adverse effects are rarely a problem because of low dosage administered. Local adverse effects (the most prominent of which is atrophy) depend on the strength of the preparation, the quantity used, the area of the body, and the skin condition being treated.
