Disorders of the oral mucosa are an area of interdisciplinary cooperation involving physicians from a diverse range of medical specialties. Diseases characterized by a similar mucosal abnormalities include lichen planus, pemphigus vulgaris, paraneoplastic pemphigus, mucous membrane pemphigoid, epidermolysis bullosa acquisita, linear IgA bullous dermatosis and chronic ulcerative stomatitis.

Introduction. Drug reaction with eosinophilia and systemic symptoms (DRESS) is a serious, potentially life-threatening syndrome with skin lesions, internal organ involvement and eosinophilia. Objective . To present the case of a 35-year-old woman with DRESS syndrome after 6 weeks of treatment with the anticonvulsant drug carbamazepine. Case report . A 35-year-old woman, suffering from depression, was admitted to hospital after a single exposure to artificial ultraviolet radiation during carbamazepine therapy. Generalized maculopapular eruptions and laboratory blood test abnormalities were recognized. After withdrawal of the causative drug and treatment with corticosteroids and antihistaminic preparations, the skin lesions disappeared and the values of laboratory blood tests improved. Conclusions . Due to the high rate of mortality in DRESS, a quick diagnosis is of crucial value. Most important is detailed history taking, immediate cessation of the causative drug, and in severe cases therapy with systemic corticosteroids. Proper diagnosis reduces the rate of fatal outcome of the disease, which is estimated at 10–38%.

Dermatitis herpetiformis (DH), bullous pemphigoid (BP), and pemphigus vulgaris (PV) are autoimmune bullous skin conditions with eosinophilic and neutrophilic infiltrations. While cytokines are crucial for the affinity and activation of different leukocyte cells in the inflammation and blister formation, there are no studies concerning a role of IL-36. The goal of the study was to analyze whether interleukin 36 is involved in pathogenesis of DH, BP, and PV. And the second aim of the study was the estimation of correlation between IL-36 and IL-17 and titers of specific antibodies in these diseases. Expression of IL-36 and IL-17 was detected in serum in all DH, BP, and PV samples. Serum levels of IL-36 and IL-17α were statistically higher in DH, BP, and PV groups as compared to the control group. IL-36α levels were statistically higher in DH patients, as compared to patients with PV and BP. Our results showed that IL-36 may be helpful in the diagnostic and monitoring of the activity of the disease. IL-36 may play a relevant role of enrolling eosinophils and neutrophils in DH, BP, and PV and finally provoke tissue injury.
