Background: Systemic juvenile xanthogranuloma is a very rare disease typically presents as skin lesions with yellow papules or nodules and is sometimes fatal. We report a case of congenital neonatal systemic juvenile xanthogranuloma with atypical skin appearance that made the diagnosis difficult.

Case Presentation: A preterm Japanese female neonate with prenatally diagnosed fetal hydrops in-utero was born with purpuric lesions involving the trunk and face. Read More

The non-Langerhans cell histiocytoses (N-LCH) represent a group of rare diseases with different clinical presentations and imaging features to classical LCH. While there is a long list of entities, only few present with musculoskeletal soft tissue and osseous manifestations alongside the more commonly reported systemic findings. Erdheim-Chester disease (ECD) is typically seen in adults as bilateral and symmetrical long bone osteosclerosis. Read More

Introduction: Juvenile xanthogranuloma (JXG) is a disorder of histiocytic proliferation that affects young children and usually presents as spontaneously regressing cutaneous lesions. JXG with systemic involvement is a rare entity associated with significant morbidity and mortality. Intracranial solitary lesions are uncommon, and when comorbid with multiple lesions of the central nervous system in young children, it has an extremely worse prognosis. Read More

Juvenile xanthogranuloma (JXG) is a type of non-Langerhans cell histiocytosis that most commonly manifests as a solitary cutaneous lesion of the head and neck in children. Intracranial JXG is extremely rare. Although it is widely known that JXG skin lesions gradually disappear over time without treatment, treatment guidelines for intracranial JXG have not been established. Read More

Histiocytosis is a rare inflammatory process characterized by pathologic infiltration and accumulation of cells derived from the monocytic lineage in normal tissue. It encompasses more than 100 different subtypes of disorders that were recently classified into five main groups: Langerhans-related histiocytosis, Rosai-Dorfman histiocytosis, cutaneous and mucocutaneous histiocytosis, malignant histiocytosis, and hemophagocytic lymphohistiocytosis and macrophage activation syndrome. Langerhans cell histiocytosis is the most common histiocytic disorder. Read More

Langerhans cell histiocytosis, Rosai-Dorfman disease, and juvenile xanthogranuloma may present at birth or any time afterward. Some patients have minimal skin or lymph node involvement, but others present with life-threatening pulmonary, hepatic, bone marrow, or central nervous system lesions. There is often a delay in diagnosis because of confusing overlap with more common neonatal diseases. Read More

Neurofibromatosis type 1 (NF1) is a complex autosomal dominant disorder associated with germline mutations in the NF1 tumor suppressor gene. NF1 belongs to a class of congenital anomaly syndromes called RASopathies, a group of rare genetic conditions caused by mutations in the Ras/mitogen-activated protein kinase pathway. Generally, NF1 patients present with dermatologic manifestations. Read More

Several dermoscopic features of juvenile xanthogranuloma (JXG) have been previously described in single cases or small case series and need to be further verified in a large sample. We aimed to investigate the dermoscopic patterns of JXG in a large case series and the correlations of these with clinical features of different histopathological subtypes of JXG. Patients who underwent dermoscopic evaluation and had a histopathological diagnosis of JXG were recruited. Read More

Juvenile xanthogranuloma (JXG) is a rare, benign histiocytic disorder of young children. It is most often present with cutaneous involvement of the head, neck and trunk region. Systemic JXG causes cutaneous lesions with extracutaneous involvements frequently seen in the orbit, liver, spleen, lung, kidney and bones. Read More

Background/objective: Juvenile xanthogranuloma (JXG) is a rarely encountered skin disorder, which is characterized by the proliferation of non-Langerhans cell histiocytes. As JXG primarily affects infants and young children, this study aims to describe the epidemiologic, clinical, and histopathologic characteristics of 44 children diagnosed with JXG at a tertiary health care center.

Methods: Fourty-four children with a histopathologic diagnosis of JXG between January 2003 and January 2017 were retrospectively reviewed. Read More

Sitosterolemia is an extremely rare autosomal recessive disease caused by mutations in either or , which encode for a sterol efflux transporter (sterolin) that pumps sterols out into the intestinal lumen or into bile. This leads to progressive accumulation of plant sterols in blood and tissues. Clinical presentation is variable and may include xanthoma, arthritis, thyroid dysfunction, premature atherosclerotic disease, splenomegaly, and hematologic manifestations. Read More

Juvenile xanthogranuloma (JXG) is the most common non-Langerhans cell histiocytic disorder in children. This report describes the case of a 28-day-old boy that presented with multiple subcutaneous nodular lesions on the trunk and extremities, and multiple red nodular lesions on the scrotum. Magnetic resonance imaging (MRI) of the brain showed a well-demarcated extra-axial dura-based mass that appeared isointense or slightly hyperintense on T1-weighted images, hypointense on T2-weighted images and had intense enhancement on gadolinium-enhanced T1-weighted images.
