Abstract
Background: The clinical and histopathological classification of erythema multiforme(EM) and Stevens-Johnson syndrome (SJS) are difficult due to a lack of clear-cut criteria. In recent studies, some authors suggested that erythema multiforme and Stevens-Johnson syndrome were clinically and histopathologically different disorders. Objective : The purpose of this study was to review the clinicopathological characteristics of the EM and SJS and to suggest specific findings for differentiating between the two diseases. Methods : Fifty four patients with EM and SJS diagnosed in the Department of Dermatology of Dong-San Hcepita1 from January 1987 through to December 1996 were studied retrospectively. Results : The results were summarized as follows. l. In view of causal factors, 54 cases were classified as drug-induced (n=22, 41%), herpes-induced (n=16, 30%), tuberculosis (n= 2, 3%), pneumonia (n=l, 2%), unknown (n=13, 24%). 2. Fifty four cases were clinically classified as SJS (n= 29, 54%), EM minor (n=-15, 2S%) and EM major (n = 10, 18%). 3. Erythema multiforme was found to be more related to herpes (13 of 25 cases) than to drugs (3 of 25 cases), while SJS was more related to drugs (19 of 29 cases) than to herpes (3 of 29 cases). 4. Varying degrees of necroti changes of keratinocytes were found in all the cases. The severity of degree or extent of necrosis was higher in patients with SJS than EM. 5. In demial changes, EM showed differences from SJS by having a denser and deeper lymphocytic infiltrate, and increased amount of extravasated erythrocytes. Conclusion : Taken together, although our findings could not provide a defmite clue to determine whether EM and SJS are different distinet entities or not, this study may be useful to differentiate and to understand the pathogenesis of EM and SJS. A prospective large scaled study should be conducted to definitively characterize these entities.
