[Benign histiocytosis: Rosai-Dorfman disease]

BACKGROUND

Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease (RDD)) is a rare entity with pathological accumulation of specific, activated macrophages, mainly in cervical lymph nodes. However, in half of patients its primary presentation is extranodal. Its aetiology is unclear; several clues point in an immunological direction. Common clinical presentation is massive cervical lymphadenopathy, but nearly half of all patients suffer from extranodal manifestation at very diverse localizations. Diagnosis is based on histopathological findings: emperipolesis and S-100 positive histiocytes. Taking into account its benign character, caution in implementing therapy is recommended. Therapeutic options are limited to specific situations only.

CASE DESCRIPTIONS

Two patients with known RDD presented at our outpatient clinic. A 75-year-old woman with two tumours in her right breast and an 83-year-old man with constipation - most likely due to a kidney tumour. Microscopic findings finally confirmed extranodal manifestation of RDD.

CONCLUSION

Extranodal manifestations of RDD present in various forms and on history taking, physical examination and radiological imaging may resemble malignancies.

Extranodal rosai-dorfman disease presenting as incidental bone tumor: a case report

We report a case of primary extranodal Rosai-Dorfman disease presenting as a painless lesion in the left ilium of a 71-year-old African-American man.

Rosai-Dorfman disease

Sinus histiocytosis with massive lymphadenopathy, also known as Rosai-Dorfman disease, is a rare histiocytic proliferative disorder of unknown aetiology. The classic presentation of Rosai-Dorfman disease is massive, bilateral, painless cervical lymphadenopathy. Extranodal disease is also common, often with a particular predilection for the head and neck regions. We report a rare case of Rosai-Dorfman disease with nodal and multiple extranodal manifestations in a 13-year-old girl. The patient had cervical and mediastinal lymphadenopathy, multiple soft tissue swellings of the scalp, bilateral proptosis and goitre due to thyroid gland involvement. She responded to steroids, with remission of the swellings and symptoms. This case is being reported for its rarity, multiple extranodal manifestations and thyroid gland involvement. Thyroid gland involvement in Rosai-Dorfman disease has rarely been reported in the literature.

Rosai-Dorfman disease involving the neurohypophysis

Rosai-Dorfman disease is a rare, histiocytic proliferative disorder of unknown etiology commonly affecting lymph nodes. Extranodal lesions with or without nodal involvement also occur. We report the case of a 63 year-old woman with disseminated Rosai-Dorfman disease involving the neurohypophysis and associated with adenohypophysial PRL cell hyperplasia.

Rosai-Dorfman syndrome: a case report

A 30-year-old woman presented with multiple swellings in the neck associated with febrile illness of 3 months' duration. She also complained of nasal blockade. The swellings were non-tender, non-matted with about 4-5 cm in size. CT scan of nose and paranasal sinuses revealed a mass in the right nasal cavity. Histopathology from cervical lymph nodes which showed large clusters of mononuclear foamy histiocytes-emperipolesis of lymphocytes or lymphophagocytosis was seen in some cells. The patient was treated with antibiotics and prednisolone.

[Mammary gland Rosai Dorfman disease. A case report and literature review]

Rosai-Dorfman disease (RDD) is an uncommon idiopathic, benign histiocytic lesion. It generally involves the cervical lymph nodes and, less often the extranodal sites. Involvement of the breast is rare, with about 18 cases reported in the English literature to date. We describe a case of breast involvement by extranodal RDD. The patient was a 67 year old woman with a solid breast lesion that was detected during mammography screening. Microscopically, the lesion was well-circumscribed, and made of sheets of S-100 protein-positive large histiocytes displaying lymphocytophagocytosis. Because the clinical presentation and imaging characteristics of RDD frequently mimics invasive breast carcinoma, awareness and appropriate diagnosis of this entity is essential for proper treatment.

Rosai-Dorfman disease of the subglottis diagnosed by ultrasound-guided fine-needle aspiration biopsy: a case report

We report a case of subglottic narrowing caused by an extranodal deposit of sinus histiocytosis in a 55-year-old man. To the best of our knowledge, no previous reports have described diagnosis using sonographic-guided fine-needle aspiration cytology for Rosai-Dorfman disease of the subglottis. This patient was diagnosed by sonographic-guided fine-needle aspiration biopsy, which revealed lymphocytes, plasma cells, and many foamy, multinuclear histiocytes with preserved lymphocytes in their cytoplasm (emperipolesis). The patient underwent an incisional biopsy of the tumor and received postoperative steroids and low-dose chemotherapy. The subglottic tumor was markedly regressed 6 months later.

Sinus histiocytosis with massive lymphadenopathy: a case report with pleural effusion and cervical lymphadenopathy

Sinus histiocytosis with massive lymphadenopathy (SHML) is a rare disorder characterized by a nonneoplastic proliferation of distinctive histiocyte cells within lymph node sinuses and lymphatics in extranodal sites. SHML occurs worldwide and is primarily a disease of childhood and early adulthood. A 26-yr-old man presented with painless palpable lymph node in cervical area. Radiographic studies revealed pleural effusion with lymphadenopathy and calcification in mediastinum. The cervical lymph node biopsy showed dilated sinuses filled with histiocytes with clear cytoplasm. The cells stained positive with CD68 and S-100. These cytologic and immunohistochemical findings were considered consistent with the diagnosis of SHML.

CONGENITAL ROSAI-DORFMAN DISEASE WITHOUT LYMPHADENOPATHY

Rosai-Dorfman disease (RDD) is a rare histiocytic proliferative disorder with massive lymphadenopathy. We here describe RDD of a neonate who presented with paleness and hepatosplenomegaly but not lymph-node swelling. Routine laboratory studies showed anemia, thrombocytopenia, and an elevated value of gamma-glutamyl transpeptidase. Histological examination of the liver revealed a proliferation of histiocytes with abundant eosinophilic cytoplasm, which were positive for S-100 protein and CD68 but not CD1a and did not reveal Birbeck granules. Radiological studies showed hepatosplenomegaly and a narrowing of the hepatic vein, which might have contributed to hypersplenism resulting in anemia and thrombocytopenia. This case is thought to be congenital RDD without lymphadenopathy.

Isolated intracranial Rosai?-?Dorfman disease mimicking meningioma in a child

A 9-year-old boy presented with a 12-month history of headaches and recent grand mal seizures. Computed tomography and magnetic resonance imaging of the brain revealed an enhancing right frontal convexity lesion. The preoperative diagnosis was meningioma. However, histological examination was diagnostic of Rosai-Dorfman disease. Rosai-Dorfman disease confined to the intracranial compartment is very rare, of 34 reported cases only one presented in the first decade. Optimal treatment has not been established, but complete surgical resection alone seems effective and allows histological distinction from meningioma.

Rosai-Dorfman disease in an Asian Indian woman with classic generalized lymphadenopathy and nasal obstruction: a case report

Rosai-Dorfman disease is rare. When it does occur, it usually affects children, and it has a propensity for whites and blacks as opposed to members of other races. We report the case of a 45-year-old Asian Indian woman who presented with painful masses in the area of the axillary, cervical, and inguinal lymph nodes. She had a decade-long history of tonic-clonic seizures and a recent history of digestive complaints and progressive nasal stuffiness. Endoscopic examination of the left nasal cavity revealed the presence of submucosal bulges along the septum and the lateral wall; hypertrophy of the adenoids was also noted. Histologic analysis of lymph node specimens revealed dilated parenchymal sinuses, germinal activity with infiltration of numerous histiocytes (emperipolesis), and chronic inflammatory cells. The patient was diagnosed with Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy) with atypical extranodal involvement (the nasal area). An aggressive course of polychemotherapy thrice daily was initiated, but it had no lasting effect, and the patient died 8 months later of an undetermined cause. Our patient's age at the onset of her disease, her race, and the extranodal involvement make this case of Rosai-Dorfman disease unusual and perhaps unique.

Isolated intracranial Rosai-Dorfman disease mimicking suprasellar meningioma: case report with review of the literature

Rosai-Dorfman disease (RDD) is an idiopathic histiocytic proliferation affecting the lymph nodes. Isolated intracranial RDD is rare and usually appears as a well-defined, dural-based lesion without lymphadenopathy. The clinical and radiological features of intracranial RDD are similar to meningioma. Histopathology and immunohistochemistry are essential for a definitive diagnosis. This is a report of a 43-year old male with isolated intracranial RDD, which manifested as a suprasellar meningioma. The clinical, radiological and pathological aspects of the disease are discussed within the context of a review of previously reported cases.

Report of two cases of Rosai-Dorfman disease with only skin involvement

Although cutaneous localization associated with lymphadenopathy is a common phenomenon in Rosai-Dorfman disease, cutaneous and subcutaneous involvement alone occurs only rarely. We herein report two cases of cutaneous lesions in the absence of lymph node localization and systemic symptoms or signs. Characteristic features of the disease, such as emperipolesis, were evident in both cases.

[Rosai-Dorfman's disease (sinus histiocytosis with massive lymphadenopathy): a report of a case and bibliographic review]

Rosai-Dorfman's illness, also denominated sinus histiocytosis with massive lymphadenopathy is considered benign entity of unknown etiology; although it is believed it may be due to alterations of immune system. It was described in 1969 by Rosai and Dorfman and there are nearly 500 cases worldwide reported. The most frequent clinical manifestation is massive lymph node enlargement, mainly cervical, but almost in the fifth percent of cases any lymph node may be affected. Diagnosis is pathological, without treatment of choice, evolution is often spontaneous resolution. In extraganglionar compromise, illness may be progressive and fatal. A45 year-old woman with cervical and nasal lymphadenopathy and fever is presented. Biopsy report: histiocytosis with emperipolesis phenomenon and immunohistochemical markers S-100, CD48, and CD45, positives. Encountering total T lymphopenia, mainly CD4+ diminished relationship CD4/CD8 and polyclonal gammopathy. Relevant in this case, clinical presentation multiple lymph nodes, distinct of other reported in our country whose presentation was mainly cutaneous plus association among Rosai-Dorfman with immunological changes and good clinical response to immunomodulator treatment, not previously seen, as in this patient.

Rosai-Dorfman disease in the differential diagnosis of cervical lymphadenopathy

Rosai-Dorfman Disease or Sinus Histiocytosis with Massive Lymphadenopathy (SHML) is a rare benign disease of unknown etiology, which presents with cervical lymphadenopathy. It is usually seen in younger patients. The extranodal form affect various regions of the head and neck, and is more common in patients with immune abnormalities. It is a self-limited and seldom life-threatening disease, rendering therapy unnecessary in most cases. For those who require therapy because of persistent or worsening symptoms, treatments modalities include surgery, chemotherapy, radiotherapy and steroids. The authors describe one case of a 43-year-old man with bilateral cervical masses, nasal obstruction, fever, weight loss and decreased vision with 6 months duration. As his social history was positive for tobacco and alcohol use, the initial diagnosis was a possible rhinopharyngeal malignant tumor. Medical investigation established the diagnosis of SHML. After therapy, the 6-month follow-up evidenced the patient's clinical improvement, although cervical masses persisted. The clinical presentation, histological features, pathogenesis and treatment of this case are discussed.

Rosai Dorfman disease

Rosai Dorfman disease is rare benign disease of lymph nodes but extra nodal sites may also be affected. It was discovered in 1969. Probably this is the first case report of such case in Bangladesh. Recently I found a girl of 14 years old with gradual painless massive cervical lymphadenopathy for six weeks duration with no signs of acute inflammation. Along with lymphadenopathy she had mild low grade fever. The common probable causes of lymphadepathy were excluded by history, physical examination and laboratory examination. Excisional biopsy and later histopathology confirmed the case as Rosai Dorfman disease. This disease usually follows a benign course and does not require any treatment other then periodic follow up. In course of time it gradually subside. In our case the patient comes every month for follow up. She is doing better now, there is mild regression of the size of lymphnodes. She is attending school regularly and appearing in exams as well. Now our patient is receiving vitamins & occasional paracetamol only.

Rosai Dorfman disease--a rare entity report of two cases with nodal and extranodal involvement

Rosai Dorfman Disease (RDD) also known as Sinus Histiocytosis with Massive Lymphadenopathy (SHML)is a very rare variety of reactive histiocytoses. It commonly involves cervical lymph nodes; although involvement of other lymph node regions, skin and other organ involvement can occur. It has a good prognosis so there is a need to differentiate it from other lympho proliferative disorders of poorer prognosis. We present two cases of this rare disorder illustrating its clinical spectrum; a 22 years old woman with involvement of submandibular lymph nodes, nasal septum and sub-glottic region and a 45 years old male with prominent skin involvement.

Multifocal nodal and extranodal Rosai-Dorfman disease initially diagnosed as histiocytic lymphoma

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy (SHML), is a systemic disease involving nodal and extranodal tissues. We report a 48-year-old female with recurrent nasal obstruction due to polypoidal masses involving the nasal sinuses, turbinates and septum bilaterally, and lumps in the right infra-orbital region and region of the right lacrimal sac. A 4 cm right upper neck mass was also noted, which was initially diagnosed as histiocytic lymphoma. Histopathology of the nasal and infraorbital lesions revealed fibro-inflammatory masses containing histiocytic cells with large vesicular nuclei and abundant foamy cytoplasm exhibiting emperipolesis and lymphophagocytosis, admixed with scattered plasma cells and lymphocytes. These histiocytes revealed immunohistochemical positivity for S-100 protein and CD68, but were negative for CDla. The findings supported a diagnosis of RDD. This report serves to remind pathologists and clinicians of the extranodal manifestations of RDD and its potential confusion with lymphomas.
