Objective: We investigated the clinical features of SCD caused by Rhus.
Methods: We conducted a retrospective analysis of 11 patients with SCD caused Rhus in Dong-A University hospital and Haeundae Paik Hospital.
Results: Nine (81.8%) were women, and average age was 58.91±10.29 years (range 45-75). The way of Rhus ingestion was boiled chicken with Rhus (n=9, 81.8%), Rhus vegetables (n=1), and Rhus sap (n=1). All patients experienced generalized pruritus and erythematous maculopapular rash. The patients developed erythema multiforme (n=2), vesiculobullous lesion (n=3), urticaria (n=3), and angioedema (n=1). Extracutaneous symptoms were duodenal ischemia (n=1), hypotension (n=2), fever (n=4), and oral mucositis (n=1). The mean latency period was 1.45±0.69 days (range 1-3), and mean recovery times were 12.27±3.77 days (range 5-18). Systemic corticosteroid was administered in 10 (90.9%) for 18.09±15.44 days (range 4-47).
Conclusions: SCD from ingestion of Rhus showed various cutaneous manifestation mainly erythematous maculopapuar eruption, and also extracutaneous symptoms. Most of the patients recovered well with the treatment of systemic corticosteroids.
