Psychiatric-Medical ComorbidityCitalopram-induced subacute cutaneous lupus erythematosus - first case and review concerning photosensitivity in selective serotonin reuptake inhibitors

ObjectiveThis report describes a case of subacute cutaneous lupus erythematosus (SCLE) in a patient treated with citalopram and discusses evidence linking selective serotonin reuptake inhibitors (SSRIs) to the induction of photosensitivity.MethodCase report and review of published literature.ResultsA 71-year-old woman with major depression developed 2 days after intake of 20 mg citalopram a strongly itching and largely dimensioned confluencing erythema with infiltrations and blisters all over the trunk with fever and malaise. Histological and laboratory investigations were consistent with the diagnosis of SCLE. After stopping citalopram intake, dermatologic symptoms significantly improved within 2 weeks. SSRIs have been associated with 14 cases of adverse cutaneous events as a result of SSRI-induced photosensitivity. No case of SSRI-induced SCLE has been described.ConclusionIn clinical practice, indication and dosage of citalopram and other SSRIs should be carefully monitored. In the case of a SSRI-induced photosensitivity, medication can be switched to an antidepressant from another class.
