It has been used as a test for cellular immunity in patients with neoplastic and immunologic disorders, and also for the treatment of alopecia areata and persistent verruca vulgaris. However, since dinitrochlorobenzene has been shown to have potentially carcinogenic effects, the use of dinitrochlorobenzene in these relatively benign disorders has been a source of debate.1 Recently, the use of dinitrochlorobenzene has gained popularity as an "alternative" treatment in human immunodeficiency virus (HIV) infection. Use of dinitrochlorobenzene has been promulgated through the gay press, based on the theory that its delayed-type hypersensitivity reaction activates the immune system, resulting in an increased number of T4 cells and elevation of T4/T8 ratios (San Francisco Sentinel, Sept 26, 1986, pp 9, 11). We describe a patient who used dinitrochlorobenzene for this purpose and
