5 patients, all using a mephenesin -containing ointment, with an acute contact dermatitis also presented an id-like spread with erythema multiforme features. In 4 patients, patch tests were performed and since mephenesin was the common allergen in each of these cases, we may assume that this is also the cause of the erythema multiforme-like lesions.

The clinical histories of twenty children hospitalized for erythema multiforme (EM) were reviewed. Three forms of the illness were defined according to clinical criteria: minor (EMm), intermediate (EMt) and major (EMM). Previous infections were associated with the process in 30% of the cases, administration of drugs also in 30%, and a combination of the two factors in 30% of the subjects. No specific etiology was found in two cases (10%). Respiratory tract symptoms and general discomfort preceded the EMM form, and evidence of digestive organ involvement was frequent in the EMm form. Erythrocyte sedimentation rate was usually high. Postinflammatory sequelae occurred in only two cases, and one subject died in the first 24 hours.
Eighty-six cases of erythema multiforme (EM) were studied based on the distribution of skin lesions. Twenty-nine patients had distinct facial skin lesions as well as lesions on the extremities (Group A) and 57 patients had skin lesions only on the extremities (Group B). Patients in Group A were younger than those in Group B; the average ages being 7.5 and 25.2 years, respectively. In Group A, the disease occurred mainly in winter, while, in Group B, it began most frequently in summer. Preceding ulcerated pernio was seen in 11 patients of Group A, but only one of Group B. Histopathologically, both groups are compatible with a diagnosis of EM, although the seasonal occurrence of facial involvement in Group A may suggest a specific etiological relationship to cold.
Inflammation and ulceration at the epithelium-connective tissue interface, a characteristic of erythema multiforme (EM), may be associated with altered molecular attachment of basal keratinocytes. To determine the expression of basal keratinocyte-associated integrins and their basement membrane ligands in oral EM, specimens of clinically and microscopically confirmed EM (n = 12) and mucosal controls (n = 7) were stained immunohistochemically for the integrins alpha 3, beta 6, beta 1, and beta 4 and for extracellular matrix proteins laminin 1, laminin 5, collagen IV, and collagen VII using a standard avidin-biotin-peroxidase technique. In EM, results showed increased staining intensity for all integrins studied in basal and suprabasal keratinocytes. Basement membrane-associated staining of a6 and b4 was intense, but disrupted and fragmented. In EM, integrin staining was most marked at the summit of the connective tissue papillae. Laminin 5 staining was more intense than in controls, was frequently fragmented, and extended into the lamina propria. Laminin 1 staining was discontinuous and was frequently less intense than in controls. Collagen IV staining in EM was interrupted along the basement membrane. Collagen VII staining was fragmented but unchanged in intensity. These alterations in interface adhesion molecules suggest that hemidesmosome-associated molecules are important in the pathogenesis of EM. The staining intensities and patterns of expression of these adhesion molecules suggest that oral EM is initially focused in the connective tissue papillae.
Plasma C3d concentrations were measured in patients with erythema multiforme (EM) complicating herpes labialis. C3d levels were raised during cold sores but not during EM. Heat damaged red cell clearance was prolonged during EM. These observations support the concept that immune complexes disseminate herpes simplex virus (HSV) antigens to skin before the onset of EM.

In twenty patients with erythema multiforme we investigated circulating immune complexes and their deposition in the skin lesions. CIq-binding activity was elevated in ten of twenty patients, and the platelet aggregation titre was high in three of twelve tested sera. Decreased levels of C3 were seen in two and of C4 in one out of eighteen patients. Direct immunofluorescence showed a deposition of C3, IgM or IgG in the blood vessel walls of the upper dermis in four of twelve patients. These findings may suggest that transient production of circulating immune complexes and their deposition play an important role in the pathogenesis of this disease.
A survey of twenty-six cases of erythema multiforme was undertaken. All patients had oral lesions and seventeen had skin involvement, mainly on the hands. The average age was 32 years, and female patients predominated in the group. Nearly one third gave a history of a severe emotional disturbance prior to the attack, four patients developed lesions after penicillin therapy, and two presented initially with acute primary herpes simples stomatitis. Skin and mucosal biopsies were undertaken in some patients, and it was concluded that no pathognomonic features were identifiable; a subepithelial bulla, however, could occasionally help in the differential diagnosis. Other laboratory investigations, including a complete blood count, determination of herpesimplex titer, and urinalysis, were not helpful, except that the erythrocyte sedimentation rate was raised in sever cases. Possible etiologic factors were discussed in relation to the survey. It was thought that the cause is still obescure except in drug-induced cases and that the diagnosis is essentially a clinical one, since various laboratory investigations cannot be shown to produce consistent pathognomonic findings.
We report about a special case of recurring Erythema multiforme after Herpes glutealis. There closely grouped vesicles all over; only at the palms we saw target-like skin lesions.
We have reported a case of severe erythema multiforme caused by outbreaks of recurrent HSV-2 infection. The EM was debilitating and responded to the treatment of HSV with oral acyclovir. On stopping the oral acyclovir, the HSV and the EM both recurred. We recommend a trial of oral acyclovir in cases of severe EM caused by recurrent HSV.
The authors report the case of erythema multiforme characterized by its cephalic onset and its rise after association phenytoin and cranial irradiation, for glioblastoma with epileptic fits. Eight similar cases are observed in literature with the same timing. Benign outcome is not always the rule because 2 patients died. This type of reaction being not forseeing, and outcome very varying, we suggest to avoid phenytoin in patients having a cerebral tumor revealed by epilepsy and needing a cranial irradiation.
Diagnosis and particularly the management of erythema multiforme and Stevens-Johnson syndrome are controversial in medical textbooks and thus in individual cases. In these diseases, fatalities may result from various causes, including secondary infection or visceral organ damage to lung, liver, or kidneys. We present a series of 13 cases managed by one group of physicians which demonstrates the controversy in certain cases, and we review the controversy in the medical literature. Corticosteroid therapy used in this series was considered beneficial in every case by the managing physician and lifesaving in some cases. There were no fatalities in this series. Although the summation may be considered as our opinion only, the frequently suggested "controlled trial of corticosteroid therapy" can probably never be done for ethical reasons, and series such as this will have to establish the standard of therapy.
