Case report: Rosai-Dorfman disease with rare extranodal lesions in the pelvis, heart, liver and skin

Rosai-Dorfman disease (RDD), a rare form of non-Langerhans cell histiocytosis, can involve systemic extranodal lesions. Skin lesions are the most common, whereas intrapelvic, cardiac, and hepatic lesions are infrequent. The present study describes a 74-year-old woman with multiple extranodal lesions in the pelvis, heart, liver, and skin that were successfully treated with glucocorticoid therapy. She had experienced fever and persistent inflammation without cervical lymphadenopathy for several months and ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography (PET) showed abnormal FDG uptake in the left cheek; cervical, axillary, inguinal lymph nodes; periatrium; and pelvis. She was diagnosed with RDD based on skin and pelvic biopsies. Although this was an atypical case without bilateral cervical lymphadenopathy, the FDG-PET detection of inflammatory lesions led to selection of suitable biopsy sites, and pathological examination led to a correct diagnosis. Findings in this patient indicate that RDD can present with an atypical distribution of infrequent extranodal lesions, with attention required to prevent a delayed diagnosis.

An Unusual Tumor in an Uncommon Site-Orbital Rosai-Dorfman Disease: A Case Report

Rosai-Dorfman disease (RDD) is also known as Sinus Histiocytosis with Massive Lymphadenopathy. It is a rare, benign, self-limiting disease of phagocytic histiocytes presenting with massive painless cervical lymphadenopathy. RDD can present as a nodal disease and also extra-nodal involvement with episodes of exacerbation and remissions and relapses after treatment. Its etiology remains poorly understood and is highly variable in its clinical presentation and response to treatment. Its treatment is poorly defined but the prognosis is usually fair. Here we are reporting a rare, unusual clinical presentation of infraorbital soft tissue mass diagnosed as RDD with cyto-histopathological correlation. Only a few such cases have been reported in the literature.

Radiological features of Rosai-Dorfman disease: case series and review of the literature

AIM

To improve the accuracy of diagnosis of Rosai-Dorfman disease (RDD) by summarising the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics.

MATERIALS AND METHODS

The clinical manifestations, imaging findings, and pathological characteristics of 14 patients with histopathologically confirmed RDD were analysed retrospectively and a literature review was undertaken.

RESULTS

Of the 14 patients, nine had multiple lesions and five had single lesions. Eight patients had extranodal lesions, while six had mixed-type lesions. In patients with head and neck lesions, plain CT/MRI revealed irregularly shaped, well-defined, homogeneous, and mainly progressive lesions, with marked homogeneous enhancement on multiphasic contrast-enhanced imaging. One patient had dural lesions, one of which iso-intense to grey matter, with patchy hypo-intensity on T2-weighted imaging, meningeal tail signs, and characteristic crabfoot-like enhancement. Three patients with skeletal system involvement exhibited osteolytic bone destruction without sclerosis at the edges, associated soft-tissue masses, or periosteal reactions. Two patients had well-defined subcutaneous lesions, inhomogeneous density, and progressive parenchymal enhancement on contrast-enhanced CT. One patient had multiple intestinal lesions with inhomogeneous nodular thickening of the blind ascending colon and ileum, with marked and progressive enhancement.

CONCLUSION

RDD involvement is mainly multifocal, primarily in the head and neck regions. Plain CT/MRI revealed well-defined, irregularly shaped lesions with homogeneous density/signal, with marked and progressive enhancement on multiphasic contrast-enhanced imaging; however, histopathology is still required to confirm the diagnosis of RDD.

Rosai-Dorfman disease in a symptomatic elderly man

An 81-year-old man presented with anemia, fatigue, weight loss, and recurrent urinary tract infections and was found to have diffuse large adenopathy and infiltrating renal masses. Surgical excision of a lymph node and histologic evaluation led to the diagnosis of Rosai-Dorfman disease, a rare histioproliferative condition that classically presents with enlarged cervical lymph nodes bilaterally. It also can involve additional nodal chains and/or have extranodal manifestations. The condition can self-resolve or have periods of remission and reactivation.

Is it Anaplastic Thyroid Cancer, Primary Thyroid Lymphoma, or Rosai Dorfman Disease? An Elusive Histopathologic Diagnosis of a Thyroid Mass

The aim of this study is to present an elusive case of primary thyroid lymphoma (PTL), initially thought to be anaplastic thyroid carcinoma, then Rosai Dorfman disease, before the final diagnosis of PTL was made. An elderly female with hypothyroidism presented with compressive airway symptoms secondary to an enlarging neck mass. Imaging was suggestive of undifferentiated thyroid cancer. The initial biopsy was unexpectedly consistent with a lymphoproliferative disorder such as Rosai-Dorfman disease. A repeat biopsy with immunohistochemical analysis yielded a diagnosis of diffuse large B-cell lymphoma of germinal center subtype. The patient was spared thyroid surgery and started on appropriate chemotherapy. PTL is within the differential diagnosis that physicians must consider in a patient with a rapidly-enlarging neck mass. A clinical index of suspicion and early accurate diagnosis may spare the patient from unnecessary surgery that is required of most other non-hematopoeitic thyroid malignancies.

Systemic and Craniospinal Rosai Dorfman Disease with Intraparenchymal, Intramedullary and Leptomeningeal Disease

Rosai Dorfman disease is a rare histiocytic disorder of over-production of non-Langerhans histiocytes, which typically manifests with massive lymphadenopathy and sinonasal involvement. We report a rare case of systemic and disseminated craniospinal Rosai Dorfman disease with intraparenchymal and leptomeningeal involvement, but no sinus or dural-based disease. The diagnosis was established by biopsy of a hypothalamic mass. Additionally, UCSF500 Next Generation Sequencing demonstrated a solitary pathogenic alteration affecting the BRAF oncogene, which supports the morphologic and immunohistochemical diagnosis of Rosai-Dorfman disease.

Rosai-Dorfman disease: a rare presentation of extranodal involvement of isolated bone. Case report

Introduction: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis, is a rare disorder characterized by histiocyte proliferation. Case presentation: A 33-year-old man consulted the emergency department of a tertiary care institution in Cartagena de Indias, Colombia, due to a 6-month history of progressive deformity in the frontal right side of the face, associated with pain of slow progression, without any other symptoms or dermatological involvement. There were no other major findings on physical examination and laboratory tests performed were negative. Imaging scans obtained showed extensive inflammatory involvement of the frontal bone, which led to suspect osteomyelitis as the first diagnostic possibility. A biopsy of the lesion was performed with negative cultures for bacteria, which allowed establishing a diagnosis of extranodal Rosai-Dorfman disease with isolated bone involvement. Treatment with systemic corticosteroids was indicated with poor response, so methotrexate was added, achieving an evident improvement after 2 months. Conclusions: Little is known about the manifestations of Rosai-Dorfman disease and its treatment in the adult population. The present case report contributes to expanding the literature on this topic, which can present with rare symptoms that may pose challenges for its diagnosis.

Rosai-Dorfman disease presenting with solitary liver mass without lymphadenopathy: A case report

Rosai-Dorfman disease (RDD), as a lymphoproliferative disorder with unknown etiology, is commonly identified with systemic clinical manifestations in various organs. In this case study, RDD occurrence was reported with an exceedingly liver mass.

Rosai-Dorfman Disease of the Talus in a Child: A Case Report

BACKGROUND

Primary Rosai-Dorfman disease of bone is a rare disorder. Radiologic and clinical evaluation is insufficient in differentiating malignancy from these lesions.

METHODS

We present a talar lesion in a 17-month-old boy who presented with deterioration in gait pattern, limping, pain, and swelling of the left ankle of 4-months' duration. Curettage and demineralized bone matrix grafting were performed.

RESULTS

At 1 year after surgery, complete clinical and radiological healing was obtained.

CONCLUSIONS

Primary RDD of bone may present a diagnostic challenge. The condition must be included in the differential diagnosis of lytic or lucent lesions of the skeleton. Curettage and grafting provide satisfactory outcomes in talar RDD lesion in the pediatric age group.

Malignant behaviour of primary intracranial Rosai Dorfman disease: A rare presentation of a benign disease

BACKGROUND AND PURPOSE

The Rosai Dorfman disease (RDD) is a rare and usually benign lymphoproliferative disorder of unknown aetiology, typically characterized by head and neck lymphadenopathies. However, it may occasionally present with primary extra-nodal involvement including the central nervous system. We firstly described the potential malignant behaviour and fatal evolution of primary intracranial RDD.

ILLUSTRATIVE CASE

A 69-year-old woman sought clinical attention for recurrent episodes of headache, fever and malaise associated with bilateral proptosis and left lower limb paresis. The brain MRI revealed bilateral retro-bulbar and fronto-parieto-occipital subdural lesions. The body CT did not show extracranial lesions. A right fronto-parietal craniotomy was performed and a subtotal resection was achieved. The histopathological diagnosis was consistent with RDD. Despite the patient was commenced on high-dose corticosteroids, she developed a worsening respiratory distress syndrome and a rapid systemic disease progression with liver and kidney failure. Given the poor general status, adjuvant medical and radiation therapies were not deemed safe and feasible and the patient died of multi-organ failure a month later.

CONCLUSIONS

We documented an exceptional case of primary intracranial RDD with malignant behaviour characterized by rapid systemic disease progression and poor prognosis. Although RDD with intracranial location has usually a benign and self-limiting course with good response to adjuvant treatments, it hides a malignant potential that may lead patients to death.

Multimodality imaging manifestations of Rosai-Dorfman disease

Background

Rosai-Dorfman disease (RDD) is a rare lympho-histiocytic disorder of indeterminate etiology usually presenting with lymph node involvement, and infrequently with extra-nodal manifestations. The diagnosis of this condition is challenging due to the wide spectrum of disease manifestations.

Purpose

To elucidate the radiologic features of this disease using multimodality imaging in histopathologically proven cases and to identify characteristic features that would enable its differentiation from its mimics.

Material and Methods

We retrospectively evaluated imaging studies of 19 patients with histopathologically confirmed RDD presenting to our institute between January 2004 and March 2016. Imaging modalities included magnetic resonance imaging (MRI), computed tomography, FDG-positron emission tomography (PET) CT, mammography, and ultrasonography.

Results

Lymphadenopathy was the most common imaging feature in our study, seen in 11 (57.8%) cases followed by sino-nasal involvement in 7 (36.8%) cases and intracranial masses in 5 (26.3%) cases. Bilateral homogeneously enhancing cervical lymphadenopathy with avidity on FDG-PET scans was the predominant abnormality on imaging. Sino-nasal involvement manifested as homogeneously enhancing soft-tissue masses occupying the paranasal sinuses. Intracranial disease manifested as sellar/suprasellar masses, dural-based lesions along the cerebral hemispheres and choroid plexus enlargement. Unusual disease manifestations included spinal, osseous, and breast lesions.

Conclusion

Due to the high likelihood of multifocal involvement, the recognition of RDD at one site necessitates screening of other sites for disease. Homogeneously enhancing, FDG-avid lymphadenopathy and sino-nasal masses in association with hypointense extra-nodal lesions on T2-weighted MRI are imaging features which could aid the diagnosis of RDD and facilitate its differentiation from pathologies that present in a similar manner.

Disease Characteristics, Radiologic Patterns, Comorbid Diseases, and Ethnic Differences in 32 Patients With Rosai-Dorfman Disease

OBJECTIVE

Rosai-Dorfman disease (RDD) is a rare and idiopathic nonneoplastic disease of histiocytes that is characterized by lymphadenopathy and extranodal disease. In this study, we documented anatomical preferences, imaging findings, comorbid diseases, and ethnic differences in 32 RDD patients.

METHODS

We conducted a retrospective review of pathologically confirmed cases seen at our institution from 1998 to 2016. These cases were analyzed for (a) anatomical locations, (b) radiologic appearance, (c) comorbid diseases, and (d) differences between ethnic groups.

RESULTS

We found 32 patients with RDD, 18 were women and 14 were men. There were 51 lesions in all patients, 23.5% of which were nodal, involving 11 lymph node regions, and 76.5% were extranodal. Cervical lymph nodes and maxillofacial area were the most common affected nodal and extranodal locations, respectively. Only 4 (12.5%) of 32 patients had pure nodal involvement, whereas 20 (62.5%) of 32 had pure extranodal disease and 8 (25%) of 32 had mixed nodal and extranodal disease.Anatomically, RDD affected multiple organs in our cohort, including the lymphatic system, maxillofacial area (glandular and nonglandular tissues), superficial soft tissue, central nervous system, breast, peritoneum, gastrointestinal tract, and lungs.Radiologically, RDD presentation was variable from an organ to another. However, most lesions were hypermetabolic on 18F-fluorodeoxyglucose positron-emission tomography/computed tomography and isointense on T1-weighted magnetic resonance imaging. Computed tomographic findings were extremely variable between organs.Comorbid diseases were found in 11 patients. Those patients had 17 comorbid diseases; the most common were autoimmune diseases, viral diseases, and cancer.The organ distribution of RDD was slightly different between ethnic groups. The most frequent disease location for African Americans was lymph nodes; for whites, central nervous system and nonglandular maxillofacial (27.3% each); for Asians, lymph nodes, subcutaneous tissue, and nonglandular maxillofacial (25% each); and for Hispanics, lymph nodes and glandular maxillofacial (33.3% each).

CONCLUSIONS

Rosai-Dorfman disease represents a wide-spectrum disease not limited to lymph nodes. Radiologically, RDD has diverse imaging findings. However, most lesions were hypermetabolic on 18F-fluorodeoxyglucose positron-emission tomography/computed tomography and isointense on T1-weighted imaging. Patients with RDD have a high rate of comorbid diseases including autoimmune disease, viral infections, and cancer.

The Mayo Clinic Histiocytosis Working Group Consensus Statement for the Diagnosis and Evaluation of Adult Patients With Histiocytic Neoplasms: Erdheim-Chester Disease, Langerhans Cell Histiocytosis, and Rosai-Dorfman Disease

Histiocytic neoplasms, a rare and heterogeneous group of disorders, primarily include Erdheim-Chester disease, Langerhans cell histiocytosis, and Rosai-Dorfman disease. Due to their diverse clinical manifestations, the greatest challenge posed by these neoplasms is the establishment of a diagnosis, which often leads to a delay in institution of appropriate therapy. Recent insights into their genomic architecture demonstrating mitogen-activated protein kinase/extracellular signal-regulated kinase pathway mutations have now enabled potential treatment with targeted therapies in most patients. This consensus statement represents a joint document from a multidisciplinary group of physicians at Mayo Clinic who specialize in the management of adult histiocytic neoplasms. It consists of evidence- and consensus-based recommendations on when to suspect these neoplasms and what tests to order for the diagnosis and initial evaluation. In addition, it also describes the histopathologic and individual organ manifestations of these neoplasms to help the clinicians in identifying their key features. With uniform guidelines that aid in identifying these neoplasms, we hope to improve the awareness that may lead to their timely and correct diagnosis.

Mediastinal Rosai-Dorfman Disease With Widespread Lesions: When Surgical Biopsy Is Needed

Rosai-Dorfman disease (RDD) is a rare benign disorder of the histiocytes, affecting lymph nodes in its classic form. Extranodal RDD is considered the uncommon subtype and potentially impairs all tissues and intrathoracic organs. In our report, a ¹⁸F-fluorodeoxyglucose positron emission tomography scan of a mediastinal mass infiltrating the lungs and of widespread lesions suggested the presence of a metastatic disease. Open thoracic biopsy was required for immunochemistry and histopathology. Mediastinal mass with lesions disseminated throughout the body is an unusual presentation of extranodal RDD that calls for a challenging differential diagnosis to rule out the suspicion of metastatic malignancy.

Imaging features of immune-mediated genitourinary disease

PURPOSE

Imaging features of immune-mediated genitourinary diseases often overlap, and the same disease may manifest in different ways, so understanding imaging findings in the context of the patient's entire clinical picture is important in providing the correct diagnosis.

METHODS

In this article, diseases mediated by the immune system which affect the genitourinary system are reviewed. Examples of immune-mediated genitourinary disease including IgG4-related disease, post-transplant lymphoproliferative disorder, immunodeficiency-associated lymphoproliferative disorder due to immunosuppressive and immunomodulatory medications, lymphoma, leukemia, myeloma, amyloidosis, and histiocytosis.

RESULTS

Clinical and imaging features will be presented which may help narrow the differential diagnosis for each disease.

CONCLUSION

Recognition of immune-related genitourinary disease is important for appropriate medical management as they may mimic other diseases both by imaging and clinical presentation.

Isolated Multinodular Soft-Tissue Rosai-Dorfman Disease on FDG PET/CT

Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy) is a rare systemic histiocytic disorder of unknown etiology characterized by the accumulation of enlarged non-Langerhans histiocytes within lymph nodes and extranodal sites. The histiocytes display characteristic emperipolesis (nondestructive engulfment of inflammatory cells) and are CD68 and S100 positive and CD1a negative. Although extranodal disease frequently occurs with nodal involvement, isolated extranodal disease is uncommon. We report a case of isolated localized subcutaneous multinodular disease on FDG PET/CT. We also include a companion classic Rosai-Dorfman case with extensive nodal involvement and a characteristic benign clinical course with spontaneous improvement.

[Rosai-Dorfman disease in the larynx: report of a case and literature review]

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder that has nodal and extranodal manifestations. Currently no guidelines are available for the management of this disease. We report a case of laryngeal RDD that did not present with classical symptoms such as fever or lymphadenopathy and could be easily misdiagnosed as malignant tumor. The patient received minimally invasive surgeries combined with steroid therapy to preserve the laryngeal function as much as possible, and a favorable clinical outcome was obtained. Reports of similar cases in literatures were reviewed to obtain a better understanding of the disease course, diagnosis and treatment of this uncommon condition.
