Rosai-Dorfman disease, or sinus histiocytosis with massive lymphadenopathy, is a rare multisystemic disorder that was first reported by Rosai and Dorfman in 1969. It is a distinct histioproliferative disorder due to overproduction of histiocytes, which accumulate in lymph nodes. The cardiac involvement of this disease is extremely rare, and until now, only 18 cases have been reported. We report the case of a 53-year-old woman with right atrial mass mimicking myxoma, which the histopathologic evaluation revealed to be Rosai-Dorfman disease of the right atrium...

The clinical significance of pituitary uptake on routine whole body 18F-fluorodeoxyglucose (FDG) positron emission tomography/computer tomography (PET/CT) is not completely characterized. We seek to assess the potential differential diagnosis/underlying etiology of pituitary FDG uptake incidentally identified on routine PET/CT scans. A total of 24,007 PET/CT whole body scans in recent 5 years were retrospectively reviewed. Patients with maximum standardized uptake value (SUVmax) > 4.1 in the pituitary glands were identified...

Langerhans cell histiocytosis is a rare histiocytic disorder for which skin involvement and management are poorly described in adults. The aim of this retrospective monocentric study in a national reference centre is to describe the clinical characteristics, quality of life, BRAF mutation status and outcomes of skin involvement in adult patients with Langerhans cell histiocytosis. Twenty-five patients (14 females, mean age 47 years) were included, with a median follow-up of 33 months (range 4-420 months). Patients experienced poor dermatological quality of life despite low body surface involvement...

REVIEW
Laura A Drubach
An important mandate when imaging pediatric patients is the reduction of radiation exposure to the lowest possible level consistent with good quality diagnostic imaging, so individual selection of radiopharmaceutical dosage and imaging technique is essential. Although the logistics of image acquisition and the approach to interpretation mirror the more common use in adults, the challenges of imaging young children typically require greater attention to patient preparation, positioning, and supervision during imaging, with the use of parental or family engagement in the procedure, gentle restraint, and occasionally the need for sedation...

A 19-year-old male patient was observed due to having central diabetes insipidus (DI) for five years. He had a history of smoking 5-10 cigarettes a day for two years, but stopped smoking from the last month. The computerized tomography revealed thin-walled cystic lesions in different sizes more dominantly in the upper lobes and consolidated areas in the left upper and lower lobes. The wedge resection from the right lower lobe revealed pulmonary langerhans cell histiocytosis. Follow-up acid-fast bacteria (AFB) examinations revealed (+++) and antituberculous treatment was started...

Primary histiocytic tumors of the CNS are rare. The current WHO classification (2016) included 5 entities: Langerhans cell histiocytosis (LCH), Erdheim-Chester disease (ECD), Rosai-Dorfman disease (RDD), juvenile xanthogranuloma (JXG), and histiocytic sarcoma (HS) (1). The diagnosis usually is made based on the tumor differentiation as to the counterpart in normal histiocyte development. This article is protected by copyright. All rights reserved.

PURPOSE OF REVIEW: Rosai-Dorfman disease (RDD) is a rare histiocytic disorder typically presenting as painless cervical lymphadenopathy. Extranodal involvement is common and may also affect bones. Here, we present a patient with typical nodal disease and multifocal bone manifestations. Further, a systematic literature review was performed to better understand the phenotype, clinical course and treatment options of such patients. RECENT FINDINGS: RDD is a nonmalignant, classically sporadic histiocytosis...

Juvenile xanthogranuloma is a non-Langerhans cell lesion mostly limited to the skin but occasionally presenting in extracutaneous locations or associated with systemic conditions. Lesions need to be distinguished mainly from dermatofibroma, xanthoma, Langerhans cell histiocytosis, or reticulohistiocytoma. Herein, we present a hemosiderotic variant of juvenile xanthogranuloma in a 12-year-old girl, which we have not found described in literature. The lesion presented at the back of the scalp as a slowly growing yellowish polypoid lesion showing occasional bleeding...

BACKGROUND: The coexistence of Rosai-Dorfman disease (RDD) with Langerhans cell histiocytosis (LCH) is very rare, as to date only 17 cases have been reported in the english literature. The pathophysiology of this uncommon co-occurrence still remains enigmatic and a subject of various speculations. CASE PRESENTATION: We report a case of a 30-year-old female patient who presented with a pathologic fracture of the left proximal femur. Her medical history was unremarkable, there were no fever, skin lesions, lymphadenopathy or other organomegaly at physical examination...

Crystal-storing histiocytosis (CSH) is a rare histiocytic lesion, most often described in association with lymphoid malignancies, especially plasma cell myeloma or lymphomas associated with monoclonal gammopathy. A few cases have also been described in patients without an underlying lymphoid/plasmacytic neoplasm. The histiocytes are characterized by intralysosomal accumulation of crystals composed of whole or part of the immunoglobulin molecule. The pathobiology is largely unclear. It is a rare phenomenon and the available literature is restricted to case reports and a few case series...

Langerhans-cell histiocytosis (LCH) is a rare, benign bone tumor, usually occurring in children and younger adults under 20 years old. Only a few cases of solitary bone lesions of the adult spine are reported in literature, therapeutic guidelines or treatment regimens for lesions of the adult spine are not established yet to our knowledge.

BACKGROUND: Rosai-Dorfman disease is a form of histiocytosis affecting the systemic lymph nodes. Intracranial Rosai-Dorfman disease is rare and presents with extra-parenchymal or intraparenchymal proliferative mass lesions. Cranial neuropathy has not been reported in Rosai-Dorfman disease except when caused by mass effect by an adjacent lesion. PATIENT DESCRIPTION: We describe a girl with Rosai-Dorfman disease who presented with peripheral and multiple cranial neuropathies...

PURPOSE: The eosinophilic granuloma is a unifocal or multifocal Langerhans cell histiocytosis characterized by an expanding proliferation of Langerhans cells in bones. Skeletal LCH is a rare condition, and vertebral regeneration in cases of vertebral body collapse is even rarer. We report the case of a girl with spontaneous complete healing. METHODS AD RESULTS: A 3-year-old girl was referred for nighttime back pain, with no fever and no neurologic signs. Within a few days, she developed sudden painful restriction of all spine movements...

Griscelli syndrome (GS) is a rare autosomal recessive disorder resulting in pigmentary dilution of the skin and hair with variable phenotypes depending upon subtypes. Mutations in 3 distinct genes MYO5A, RAB27A, MLPH are responsible for 3 subtypes (GS1, GS2, and GS3) of GS respectively. GS subtype 2 commonly develops hemophagocytic lymphohistiocytosis (HLH) and recurrent infections due to immunodeficiency. We hereby report a 20 month old male child presenting with silvery gray hair, hypomelanosis and features of hemophagocytosis...

A 6-year-old boy presented to the pediatric emergency department with a unilateral 5 × 3-cm superficial mass on the postauricular region growing for 1 month. Point-of-care ultrasound was used to evaluate the mass, which revealed a complex cystic mass penetrating the temporal bone. After confirmatory magnetic resonance imaging, the patient was transferred for neurosurgical evaluation, and the tumor was excised. Pathology revealed Langerhans cell histiocytosis.
