A 15 year-old-male presented with concurrent sinonasal polyposis and anterior uveitis with cervical lymph node enlargement. Cervical lymph node biopsy confirmed Rosai-Dorfman disease. Though patient's eye symptoms did not respond well to topical corticosteroid treatment but he showed a remarkable regression in the size of nasal polyps and cervical lymph nodes after systemic corticosteroids. Int...

We share our experience with serial PET/CT imaging on a patient with extranodal Rosai-Dorfman disease (RDD) with hepatopancreatic involvement. RDD is a benign proliferative disorder of histiocytes mainly involving the lymph nodes. It typically presents with fever and painless cervical lymphadenopathy in young adults and less than half of RDS cases demonstrate extranodal involvement. RDD involve...

Rosai-Dorfman disease (RDD) also known as sinus histiocytosis with massive lymphadenopathy is a rare disorder of histiocytes characterized histologically by intracellular engulfment lymphocytes. It may occur in any age group, but most commonly seen children and young adults. painless, bilateral cervical lymphadenopathy. In approximately one-third patients it can variety extranodal sites where h...

Rosai-Dorfman disease (RDD) involves abnormal proliferations of oddly behaving histocytes that are not derived from the Langerhan's Cell linage. These collections tend to occur within lymph nodes, with occasional extra nodal presentation. While RDD is a rare entity itself, extra nodal cases are even more so, with even fewer reporting cardiac involvement, and previously only in adults. This repo...

The authors describe a 20-year-old man who initially developed an intradural mass in the upper cervical region and subsequently presented with nasal/paranasal sinus and posterior fossa masses, well demonstrated by CT and MR. Histopathology demonstrated dense fibrous tissue, aggregates of histiocytes with round to oval vesicular nuclei, and other features diagnostic of Rosai-Dorfman disease; a r...

Rosai-Dorfman disease (RDD) is a rare condition that causes massive lymphadenopathy, most commonly in the cervical area. Cowden syndrome (CS) hamartomas skin and mucosa predisposes individuals to various malignancies. Lhermitte-Duclos (LDD), or dysplastic cerebellar gangliocytoma, often associated with CS. A 41-year-old female all three conditions presented abnormal uterine bleeding endometrial...
