OBJECTIVE: Erythromelalgia is a rare, highly debilitating disorder characterised by severe episodes of discomfort, erythema, and desquamation of the extremities. Its causes include genetic factors, medications, and several underlying medical conditions. This paper describes a novel cause of erythromelalgia through a case report and literature review.
CASE DESCRIPTION: A 47-year-old Caucasian man presented with a two-year history of intermittent pain, redness and desquamation of the hands. He experienced several such episodes, each lasting 3-4 weeks. A skin biopsy confirmed the diagnosis of erythromelalgia. After several recurrences, he admitted to the intermittent use of pseudoephedrine as a nasal decongestant, which coincided with the episodes of erythromelalgia. Complete resolution of symptoms was reported on cessation of this medication.
CONCLUSION: Pseudoephedrine has been reported to cause a wide range of cutaneous reactions but has not been known to precipitate erythromelalgia. Recognition of this rare side effect may offer early diagnosis and reduced morbidity.
