Non-typhoidal Salmonella (NTS) is an important pathogen that causes gastroenteritis, bacteraemia, and focal infections. Herein, we present our experience with bloodstream infections caused by Salmonella in paediatric leukaemia patients, which has been reported for the first time in both Europe and the US. According to our research, NTS might be a cause of serious infections in paediatric haematology-oncology patients. Following a low bacterial diet and increasing the hygiene of both the children and their surroundings would be beneficial in preventing these infections., Competing Interests: The authors declare no conflict of interest.

Objective: To report a case of late-onset self-healing Langerhans cell histiocytosis., Case Description: A 4½-month-old female patient presenting with an eythematopurpuric eruption underwent a skin biopsy for histopathology and was first diagnosed with isolated cutaneous Langerhans cell histiocytosis. Her lesions regressed within a few months and she was retrospectively diagnosed with late-onset self-healing Langerhans cell histiocytosis after being without skin or systemic involvement in a follow-up four years later., Comments: Self-healing Langerhans cell histiocytosis, which is characterized by clonal proliferation of Langerhans cells and presents with cutaneous lesions, is a rare self-limited variant of histiocytosis and can only be diagnosed retrospectively, after the patient remains free from systemic involvement for several years. Although it presents at birth or during the neonatal period, only a few cases of its late-onset type regarding the age of onset have been reported. Purpuric lesions that appear after the neonatal period serve as a clue for late-onset self-healing Langerhans cell histiocytosis and the patients should be monitored regularly for systemic involvement if the diagnosis is confirmed by a cutaneous biopsy.

Acute generalized exanthematous pustulosis (AGEP) is a rare cutaneous rash characterized by the abrupt onset of a generalized pustular rash often accompanied by fever. There is a history of drug use in 90% of the cases. Here we have reported a 15-year-old male patient with sickle cell anemia who developed AGEP after the use of ceftriaxone. Our patient was hospitalized because of vaso-occlusive crisis and on the third day of ceftriaxone treatment, erythematous pustular lesions accompanied with fever were observed on the body and extremities. Resolution of symptoms followed discontinuation of ceftriaxone. Sensitivity to ceftriaxone was shown with a patch test. The AGEP was considered due to clinical and histopathological findings. This is the first pediatric case of AGEP due to ceftriaxone.
