Ankara, Turkey been no similar eruption before. The patient's mother stated that he had had an upper respiratory infection for a few days before the eruption emerged and that the only medication he had been given was tablets containing triprolidine hydrochloride 2.5 mg and pseudoephedrine hydrochloride 60 rag. She added that he had not previously taken these tablets. The lesion cleared completely without treatment within 2 weeks leaving no residual pigmentation. Then an oral challenge test was conducted, and an identical eruption at the same site developed 4 hours after administration of pseudoephedrine hydrochloride 30 mg. The provoked eruption resolved without any pigmentary change during the next 2 weeks. The patient was instructed to avoid all pseudoephedrine-containing medications.

Fig. 1. Fixed drug eruption caused by pseudoephedrine in the right inguinal region. of the skin or mucous membranes whenever the causative drug is taken. When the acute phase resolves, it usually leaves behind residual hyperpigmentation that becomes more prominent after each recurrence. However, in nonpigmenting fixed drug eruption, no pigmentary change occurs and the site of the drug hypersensitivity response is hypothesized to be dermal, t Although oral provocation is the most reliable means of confirming the suspected cause of a fixed drug eruption, topical open provocation on postlesional skin presents an alternative for patients who refuse oral rechallange. 2 Pseudoephedrine is widely used in many overthe-counter cold preparations for alleviation of nasal congestion. Despite its frequent use, adverse skin reactions appear to be unusual. Our search of the literature revealed 13 cutaneous reactions caused by pseudoephedrine. A severe generalized eruption (morphologic condition not specified) accompanied by joint swelling, 3 a recurrent pseudoscarlatina with distal desquamation, 4 a recurrent toxic shock syndrome,5 and a systemic contact dermatitis 6 have been reported. Fixed drug eruptions have also been known to occur in response to pseudoephedrine.,127• -11 Our patient's clinical features are in sharp contrast to other nonpigmenting fixed drug reactions caused by pseudoephedrine, which were all characterized by multiple, usually symmetric lesions. Since Shelley and Shelley 1 defined nonpigmenting fixed drug eruption as a separate entity and
emphasized its symmetric distribution, our patient's solitary lesion that faded without any pigmentation is unusual. We propose that the nonpigmenting dermal type of fixed drug eruption does not always occur in a symmetric fashion but can also appear as a solitary plaque just like the pigmenting epidermal type.
