Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a rare, benign self-limiting condition of unknown etiology. Less than a quarter of cases have only extranodal involvement and a few cases of skeletal involvement of Rosai-Dorfman disease without associated lymphadenopathy have been reported in the literature. We herein report cytohistologic findings in a case of sole sk...

Rosai-Dorfman disease is a self-limiting condition caused by histiocyte proliferation within the sinusoids of lymph nodes and in extranodal tissue. It is a rare disease, particularly in children, that progresses with extensive lymphadenopathy. This paper reports on the case of a 2-year-old child with progressive cervical lymphadenopathy associated with persistent fever and radiological findings...

We describe a rare case of sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) associated with a six-year history of autoimmune pancreatitis, which was controlled by steroid treatment. The patient presented with multiple, cervical and thoracic lymphadenopathy and abnormal, nodular opacities in the lung. Histologically, Rosai-Dorfman disease with numerous IgG4-positive cells...

Rosai-Dorfman disease is a rarely seen disease with unknown etiology. Extranodal involvement is most commonly seen in the head and neck region. Histopathologically, it is characterized by histiocytic cell proliferation. This paper presents a case of a 15-year-old male patient who presented with nasal obstruction and was surgically treated for a mass filling in the left nasal meatus that was dia...

Introduction: Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy, is a rare benign disorder characterized histologically by lymphatic sinus dilatation due to histiocyte proliferation. Rosai-Dorfman disease accompanied by IgG4 plasma cell infiltration is an even rarer situation. To the best of our knowledge, no imaging report of fluoro-deoxyglucose positron emi...

Received 27 October 2008 Accepted 30 March 2009 ABSTRACT Rosai-Dorfman disease is a rare disorder which seems to involve not only the lymph nodes but most other organs of the body. The case history is presented of a woman who was thought to have atypical carcinoma of the lung but in whom a diagnosis of Rosai-Dorfman disease was eventually made following a range of investigations including CT sc...

Rosai-Dorfman disease is a benign lymphohistiocytosis that often involve lymph nodes and present as massive lymphadenopathy with sinus histiocytosis. The disease is rarely associated with intracranial involvement. Herein, we report a 33-years-old man with recent onset of unconsciousness. According to his past medical history, he was suffering from frontal headache, ataxia and dizziness with no ...

Rosai-Dorfman Disease (RDD) also known as Sinus Histiocytosis With Massive Lymphadenopathy (SHML) is a rare and benign nonLangerhans histiocytosis. First described in 1965 by Destombes [1] then in 1969 by Rosai and Dorfman, this disease is characterized by benign histiocytic proliferation with frequent lymphophagocytosis (emperipolesis) [2]. All ages are affected but most of the patients presen...

UNLABELLED INTRODUCTION Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy, is a rare benign disorder characterized histologically by lymphatic sinus dilatation due to histiocyte proliferation. Rosai-Dorfman disease accompanied by IgG4+ plasma cell infiltration is an even rarer situation. To the best of our knowledge, no imaging report of fluoro-deoxyglucos...
