The value of local intracutaneous injections of various relatively insoluble steroid suspensions has been reported by several investigators, in the treatment of a variety of different dermatologie disorders. Most prominent among these disorders is alopecia areata, in which the response can be easily observed,1,2 and readily demonstrated to be a specific effect of the steroid not due solely to trauma or to psychic influences of the injections per se.
This modality has also been employed in papulosquamous eruptions of chronic and torpid nature, notably lichen simplex chronicus,3 psoriasis, andhypertrophie lichen planus.4 Tattooing with the Conway Dermajector as a method of introducing steroid into the skin has been championed by Aaron, Kantor, and Stromeyer. In this technique fine solid needles are driven through a film or a well of steroid suspension on the skin surface. Objections to the tattooing method include the painfulness of tattooing over the scalp or bony prominences, and the relatively inefficient delivery of steroid into the cutis. Others have employed intracutaneous injection with the standard tuberculin syringe and hypodermic needle.
