RESUMEN
The aim of the study was to analyze the characteristics of posterior reversible encephalopathy syndrome (PRES) cases treated at 10 different institutions in our country. Fifty-eight patients diagnosed with PRES were included in this study. The data of PRES cases from 10 departments of pediatric hematology/oncology were analyzed. The mean age of the patients at the time of diagnosis of PRES was 8.95±3.66 years. Most patients (80.4%) had a primary diagnosis of acute leukemia. Patients received chemotherapy (71.4%) and/or used steroids within 14 days before the diagnosis of PRES (85.7%). Hypertension was found in 83.9% of the patients. Twenty-six patients had infections and 22 of them had febrile neutropenia. The most common electrolyte disorders were hypocalcemia, hypomagnesemia, and hypopotassemia. Six patients had tumor lysis syndrome and 4 had inappropriate antidiuretic hormone syndrome. Magnetic resonance imaging was used for diagnosis in all patients. The most commonly involved regions by magnetic resonance imaging were occipital (58%), parietal (51%), and frontal lobes (45%), respectively. Twenty-five patients required intensive care and 7 patients were intubated. In conclusion, PRES may develop during the follow-up and treatment of hematological diseases. In addition to steroid and intense combined chemotherapies, immunosuppressive agents and hypertension are also factors that may be responsible for PRES.

Toxic epidermal necrolysis and Stevens-Johnson syndrome are rare mucocutaneous diseases which are associated with a prolonged course and potentially lethal outcome. They are mostly drug induced and mortality rates are very high. Although mostly skin is involved, multiple organ systems such as cardiovascular, pulmonary, gastrointestinal, and urinary systems may be affected. Here, we report a case of Stevens- Johnson Syndrome associated with methotrexate treatment who developed acute cardiac failure and gastrointestinal hemorrhage beside skin findings. He had been treated with intravenous immunglobulin and methylprednisolone succesfully and continued chemotherapy with methotrexate treatment again.
La necrólisis epidérmica tóxica y el síndrome de Stevens- Johnson son enfermedades mucocutáneas raras que están asociadas a una evolución prolongada y a un desenlace potencialmente mortal. Principalmente están inducidas por fármacos y las tasas de mortalidad son muy elevadas. Aunque la piel es la más comprometida, también pueden estar afectados múltiples aparatos o sistemas como el cardiovascular, pulmonar, gastrointestinal y urinario. En este artículo, describimos el caso de un paciente con síndrome de Stevens-Johnson asociado al tratamiento con metotrexato, quien desarrolló insuficiencia cardíaca aguda y hemorragia gastrointestinal además de las manifestaciones en la piel. El paciente recibió un tratamiento satisfactorio con metilprednisolona e inmunoglobulina por vía intravenosa y continuó la quimioterapia con metotrexato.
