Lymphadenopathy child

Allopurinol-induced drug reaction syndrome with eosinophilia and systemic symptoms (A-DRESS) is a well-described condition in adults, whereas it is uncommon among children. We describe a case of A-DRESS in a 16-year-old male with steroid-dependent nephrotic syndrome. He presented a life-threatening clinical course with persisting fever, skin rash, eosinophilia, lymphadenopathy, distributive shock, and herpesvirus 6 detection. The withdrawal of allopurinol and a combination of intravenous immunoglobulins (IVIGs) and systemic corticosteroids led to the patient's recovery without sequelae...

Pleural effusion in the pediatric population is an abnormal pathology characterized by the accumulation of fluids between the parietal and visceral pleura. The etiology of this excessive fluid accumulation can be attributed to both infectious and non-infectious factors. Notably, Streptococcus pneumoniae stands out as the predominant infectious agent responsible for this condition. Non-infectious causative factors encompass hematolymphoid malignancies, congestive heart failure, hemothorax, hypoalbuminemia, and iatrogenic causes...

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vascular proliferative condition, typically presenting as subcutaneous nodules in the head and neck region of middle-aged women. Kimura disease (KD) is a benign condition that presents with subcutaneous nodules in a similar distribution with lymphadenopathy and eosinophilia, typically in Asian adult males. These diseases are often discussed together, including whether they exist on a spectrum or if they represent separate disease entities. Both are very rare in the pediatric population; in this report we highlight the case of a 10-year-old Caucasian male presenting with ALHE and KD...

Patients undergoing therapy for T cell acute lymphoblastic leukemia are at risk of infections during their treatment course. Cat scratch disease caused by Bartonella hensalae can masquerade as leukemic relapse and cause systemic infection. Obtaining a thorough exposure history may aid clinicians in making the diagnosis.

A 3-year-old boy presented with acute headache, vomiting and right focal clonic seizures without history of fever, joint pain or altered sensorium. Neuroimaging showed multifocal contrast enhancing lesions with significant perilesional edema. CECT chest and abdomen showed multiple variable sized nodules in the lungs and hypodense lesion in liver with mesenteric lymphadenopathy. There was persistent eosinophilia with maximum upto 35 %. Liver biopsy and brain biopsy revealed Cladophialophora bantiana. He was treated with IV liposomal amphotericin and voriconazole for 6 weeks with repeat neuroimaging showing more than 50 % resolution of the intracranial lesions...

MEVALONATE KINASE DEFICIENCY. Mevalonate kinase deficiency is a rare, autosomal recessive, auto- inflammatory disease, linked to mutations in the gene MVK, resulting in the activation of pyrin inflammasome and hypersecretion of interleukin-1β (IL-1β). The clinical spectrum realizes a continuum which extends from the mild phenotype of the partial MVK deficiency (hyperimmunoglobulinemia D) resulting in periodic fever syndrome to a letal form of mevalonate aciduria (MA, complete MVK deficiency). Symptoms occur before the age of one, often with a trigger...

INTRODUCTION: Rosai-Dorfman disease (RDD) is a sinus histiocytosis with massive lymphadenopathy. This rare condition is a benign disease of unknown etiology. Bilateral orbital localization of RDD is rare. OBSERVATION: The authors report the case of a 6-year-old child who presented with bilateral orbital-palpebral masses associated with chronic cervical lymphadenopathy. There were no laboratory signs of inflammation. Serological and tuberculosis screening tests were negative...

BACKGROUND: Kawasaki disease (KD) is an acute systemic vasculitis of unknown etiology that affects infants and young children but is extremely rare in neonates, especially afebrile KD. We present a case of KD without fever in a neonate and review the literature on KD in neonates. CASE PRESENTATION: A newborn female was hospitalized because her peripheral blood leukocytes increased for half a day. The admission diagnosis was considered neonatal sepsis and bacterial meningitis...

BACKGROUND: H Syndrome is a rare genetic condition caused by biallelic pathogenic variants in the SLC29A3 gene. It is characterized by a wide range of clinical manifestations, many of which are related to the immune-rheumatological field. These include scleroderma-like skin changes, deforming arthritis, and enlarged lymph nodes. The condition also features cardiac and endocrine defects, as well as hearing loss, for which the immune pathogenesis appears less clear. Immunomodulatory medications have been shown to improve many symptoms in recent experiences...

BACKGROUND: Systemic juvenile idiopathic arthritis (SJIA) is a form of childhood arthritis with clinical features such as fever, lymphadenopathy, arthritis, rash, and serositis. It seriously affects the growth and development of children and has a high rate of disability and mortality. SJIA may result from genetic, infectious, or autoimmune factors since the precise source of the disease is unknown. Our study aims to develop a genetic-based diagnostic model to explore the identification of SJIA at the genetic level...

Introduction. Childhood Hodgkin lymphoma (HL) is often curable, but in Sub-Saharan Africa (SSA), access to standard treatments like combined chemotherapy and radiotherapy is limited. This study aimed at evaluating the effectiveness of using chemotherapy alone for children with HL in SSA. Methods. We searched Medline, Embase, Cinahl Plus and Cochrane Central databases for records of studies that evaluated childhood HL survival outcomes from January 2000 to December 2022. Results. Six observational studies were identified for inclusion, and 3 were included in the meta-analysis...

INTRODUCTION: Pigmented hypertrichosis with insulin-dependent diabetes mellitus (PHID) syndrome is a rare disease, and part of the cluster Histiocytosis-lymphadenopathy plus syndrome (H syndrome), which is associated with mutations in the SLC29A3 gene. Patients with PHID show clinical features of H syndrome, but also have insulin-dependent diabetes mellitus. The PHID associated diabetes has previously been described as predominantly in absence of pancreatic autoantibodies. Case Series Presentation: Through an open call in two international diabetes registers, clinical and genetic characteristics of 7 PHID patients in 6 treatment centres were collected after informed consent...

INTRODUCTION: During the Covid-19 era, acute abdomen and mesenteric lymphadenopathy were encountered as frequent mimic of appendicitis. This phenomenon can further complicate the diagnosis of acute abdominal conditions, not solely due to bacterial or viral intestinal infections but also attributable to post-infectious acute inflammatory states resulting in either undertreatment of inflammatory conditions or unnecessary surgery. CASE PRESENTATION: In this case study, we present the case of an 11-year-old female who initially presented with fever and right lower quadrant abdominal pain, raising concerns of appendicitis...

A 1-year-old male child presented with whitish discoloration of pupil of the left eye and swelling over the left axilla. A contrast-enhanced magnetic resonance imaging of the brain and orbits performed revealed left eye extra-ocular retinoblastoma. 18F-fluorodeoxyglucose positron emission tomography/computed tomography scan was done in this child as a part of baseline staging of retinoblastoma in an ongoing research project. The scan revealed left eye extra-ocular retinoblastoma along with calcified left axillary level I lymph node...

BACKGROUND: Pediatric esthesioneuroblastoma (EN) can infiltrate skull base anatomy, presenting challenges due to high radiation doses and pediatric tissue sensitivity. This study reports outcomes of pediatric EN treated with proton radiotherapy (PT). PROCEDURE: Using an IRB-approved prospective outcomes registry, we evaluated patient, tumor, and treatment-related variables impacting disease control and toxicity in pediatric nonmetastatic EN treated with modern multimodality therapy, including PT...

We describe a case of congenital syphilis in an adopted infant with a unique dermatologic presentation of scalp granulomas, along with lymphadenopathy, anemia, and elevated liver transaminases. To our knowledge, this cutaneous morphology has not been previously reported in the literature. This case highlights the varied clinical presentation of congenital syphilis and the diagnostic challenge it poses for clinicians, especially in the context of unknown prenatal history/unknown risk factors, or if syphilis is acquired during pregnancy after routine screening is performed...

A previously fit and well girl of middle-childhood age presented to her local emergency department after waking with upper-facial swelling. She had a 24-hour preceding history of mild vomiting illness and fatigue. Examination revealed palpable splenomegaly and mild cervical lymphadenopathy, with pitting oedema of the forehead, nasal bridge and eyelids. Admission full blood count showed anaemia and neutropenia, and further investigations confirmed a diagnosis of acute lymphoblastic B-cell leukaemia. X-ray of the chest and CT imaging did not reveal any local facial mass, veno-occlusive disease or mediastinal pathology to explain her facial swelling...

Kerion Celsi is an inflammatory, deep fungal infection of the scalp. It is rare in neonates but gets more common in children about 3 years and older. It represents with swelling, boggy lesions, pain, alopecia and purulent secretions. Secondary bacterial infection is not unusual after maceration. Extracutaneous manifestations include regional lymphadenopathy, fever and very rare fungemia. Id-reactions can occur. Diagnosis is based on clinical suspicion, clinical examination and medical history. Diagnosis should be confirmed by microscopy, fungal culture and molecular procedures...
