Rosai-Dorfman disease or sinus histiocytosis with massive lymphadenopathy is a rare disorder that typically manifests as lymphadenopathy and systemic symptoms whose etiology remains poorly elucidated. The diagnosis is based on immunohistochemistry. Its treatment is poorly defined but the prognosis is usually favorable. Here we report a 14 year old boy who presented with massive bilateral cervi...

Rosai-Dorfman disease is a rare benign histiocytic disease that infrequently presents in the spine. We report a case of Rosai-Dorfman disease isolated to the epidural thoracic spine in a 26-year-old male. To our knowledge, this is the 15th reported case of isolated spinal disease and only the fourth case of isolated thoracic epidural disease. Given its rarity as well as non-specific symptoms an...

CRDD: cutaneous Rosai-Dorfman disease RDD: Rosai-Dorfman disease INTRODUCTION Rosai-Dorfman disease (RDD) is a benign nonLangerhans cell histiocytic disorder often involving the cervical lymph nodes. Extranodal disease was reported in 43% of patients with RDD in a review of the literature, with the skin reported to be the most common extranodal site. In the absence of lymph node involvement, RD...

Rosai-Dorfman disease is a benign histiocytic proliferative disorder of unknown etiology. The disease mainly affects lymph node tissue, although it is rarely confined to the skin. Here, we describe a 53-year-old woman with purely cutaneous Rosai-Dorfman disease. The patient presented with a large pigmented plaque on her left leg, and sparse erythematous papules on her face and arms. A complete ...

INTRODUCTION Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman Disease, is a rare and benign source of lymphadenopathy first described in 1969, which mimics neoplastic processes. This disease commonly presents in children and young adults with supra-diaphragmatic lymphadenopathy or extranodal lesions consisting of tissue infiltrates composed of a polyclonal populatio...

ESR: erythrocyte sedimentation rate INTRODUCTION Rosai-Dorfman disease, also called sinus histiocytosis with massive lymphadenopathy, is a rare histiocytic condition of unknown etiology first described in 1969. Primary cutaneous manifestation without systemic involvement of Rosai-Dorfman disease is even more uncommon. Here we present a case of primary cutaneous manifestation of Rosai-Dorfman di...

Rosai-Dorfman disease is a rare, benign histiocytic proliferative disorder that usually affects the lymph nodes. Although extranodal involvement has been reported in diverse sites, manifestation in the cardiovascular system is extremely rare. Specifically, cardiac involvement in Rosai-Dorfman disease is an extraordinarily infrequent event. We describe a case of a 36-year-old female who presente...

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 scans, positron emission tomography (PET) and histological ...
