Is Rosai-Dorfman disease malignant?

Is Rosai-Dorfman disease malignant?

Rosai-Dorfman disease (RDD) or sinus histiocytosis with massive lymphadenopathy (SHML) is primarily a nodal-based, idiopathic, benign proliferative disorder of histiocytes with 43% of these cases also involving extranodal sites. The breast is an unusual site of occurrence of RDD.

What do you call the microscopic pathologic hallmark of Rosai-Dorfman disease?

The hallmark of Rosai-Dorfman disease is emperipolesis, in which lymphocytes and other inflammatory cells reside undisturbed within the cytoplasm of the histiocytes (figures 3, 4, arrows).

Is Rosai-Dorfman an autoimmune disease?

It is characterized by a non-clonal proliferation of distinctive cells of macrophage or histiocyte lineage, that primarily accumulate in lymph nodes [1]. We present 2 case reports in which patients were found to have an autoimmune disease as well as a rare, benign histiocytic disorder known as Rosai-Dorfman disease.

Is Rosai-Dorfman genetic?

Nevertheless, we propose that Rosai–Dorfman disease is a clonal histiocytic disorder driven by genetic alterations, at least in mutated cases, similar to Langerhans cell histiocytosis and other non-Langerhans cell histiocytosis histiocytoses.

Is Rosai-Dorfman disease serious?

In some cases of Rosai-Dorfman disease, the accumulation of histiocytes into masses may cause compression of vital organs potentially resulting in serious complications. In some cases, the lymph nodes may not be affected.

Who discovered Rosai-Dorfman?

In 1965, Pierre-Paul Louis Lucien Destombes had described, in French, four patients having “adenitis with lipid excess” which is recognized as the original description of the condition. Therefore, the condition is sometimes called “Destombes-Rosai-Dorfman disease”.

What is RD diagnosis?

The diagnosis of Rosai-Dorfman (RD) is made following a biopsy of the affected tissue. A small piece of the tissue is obtained so that it can be viewed under a microscope by a pathologist. If the cells in the tissue have certain specific characteristics, the diagnosis of RD can be made.

How do you treat Rosai-Dorfman?

Treatments and overall response rates (ORR) in patients with Rosai-Dorfman disease. Corticosteroids were used as the first-line therapy in 17 (27%) patients. Of these, responses were observed in in 56% of the cases, with a maximum response duration of 71 months and a relapse rate of 53%.

Is Rosai-Dorfman fatal?

Despite the disease having relatively good prognosis, the patient was dead within a month of confirmed diagnosis, occurring in <3% of Rosai–Dorfman disease cases.

Is Rosai-Dorfman disease curable?

In many cases, the symptoms of Rosai-Dorfman disease may disappear without treatment (spontaneous remission) within in months or a few years. Clinical observation without treatment is preferred for individuals with Rosai-Dorfman disease whenever possible. In many cases, no therapy will be necessary.

What is RDD diagnosis?

Rosai-Dorfman disease (RDD), first described in 1969, is a disease that occurs when the body produces too many histiocytes in the lymph nodes. These histiocytes most often accumulate in the nodes in the neck (cervical nodes), though other lymph nodes and other parts of the body may also be affected.

What is RD in medical diagnosis?

Rosai-Dorfman disease (RD), also known as sinus histiocytosis with massive lymphadenopathy (SHML), is a rare histiocytic disorder which involves the over-production of a type of white blood cell called non Langerhans sinus histiocyte.

Is Rosai-Dorfman curable?
