Sinus histiocytosis with massive lymphadenopathy (SHML), also designated as Rosai-Dorfman disease (RDD), is a rare benign reactive lymphoproliferative disorder. It is defined by a characteristic histopathology with sinus histiocytosis and haemophagocytosis known as emperipolesis. In histiocytes S100 is strongly expressed, whereas CD1a staining typically is negative. The disease mainly manifests at a single lymph node; however, multilocular and extranodal affection can occur. Causative infectious agents, and virus infections in particular, have repeatedly been suspected, although until now the origin of the disease has been unclear. Four cases of RDD (two nodal sites and two extranodal upper respiratory tract sites) were analysed for parvovirus B19 (B19) infection by immunohistochemistry to detect B19 capsid proteins VP1/VP2. In all the four cases, huge numbers of B19-positive cells were partly detected. The positive cells were identified either as lymphocytes or, in one extranodal case, also as respiratory epithelial cells. This is the first report of B19 infection in RDD tissue, indicating that B19 may be associated with the pathogenesis of SHML.

Sinus histiocytosis with massive lymphadenopathy (SHML) also called as Rosai Dorfman disease is a rare histiocytic proliferative disorder of unknown etiology. Histological features currently define it. Persistent painless lymphadenopathy due to expansion of sinuses infiltrated with benign histiocytes and plasma cells and emperipolesis are the characteristic features of SHML. Our study includes seven cases (5 nodal and 2 extranodal) of SHML over a 5-year period whose slides and blocks were reviewed. IHC was performed on the main lesion, from a panel of S100, CD68, LCA, CD20, CD3, CD30, CD43, bcl2, cytokeratin and epithelial membrane antigen. In our series we have work up available in 7 cases out of which a detailed follow-up is available in 5 patients. Out of these 5 patients, 4 have a stable disease, while one developed histiocytic sarcoma after a gap of four years.

Sinus histiocytosis with massive lymphadenopathy (SHML) is a rare, painless lymphoproliferative disorder of unknown origin with a usually benign course. About 40% of the patients show an extranodal involvement with skin being the most common site in 27% of these patients. We describe a patient with widespread disease involving the respiratory tract, kidneys and skin. Histopathology revealed the characteristic features of SHML with emperipolesis and immunohistochemical positivity of histiocytes for S100 and macrophage-associated antigens.

Rosai-Dorfman disease is a rare benign idiopathic histioproliferative disorder usually manifesting as massive painless adenopathy. Extranodal involvement of the Central Nervous System (CNS) mimicking a skull base meningioma is rare. A 42-year-old male presented with painless, progressive left visual loss of 4 months duration. Clinically, he had a left ptosis, proptosis and ophthalmoplegia. Magnetic Resonance Imaging (MRI) of the brain with gadolinium revealed a destructive lesion of the left orbital apex, middle cranial fossa and cavernous sinus. He was treated with corticosteroids and underwent debulking. Pathology showed inflammatory infiltrate in the absence of an infectious agent, emperipolesis and a positive S100 stain was consistent with Rosai-Dorfman disease. As there was no improvement following steroids and debulking, he underwent radiation therapy with significant improvement of his symptoms. Although a rare entity, Rosai-Dorfman disease should be considered in the differential of a skull base lesion.

Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a rare disease that typically occurs in lymph nodes. While many body sites have been reported to be involved in extranodal manifestations of the disease, the cardiovascular system has been largely absent in this literature. We report two cases of Rosai-Dorfman disease that involves the heart. Case 1 was a 40-year-old man with chronic myelomonocytic leukemia who was incidentally noted to have Rosai-Dorfman disease on autopsy after succumbing to respiratory failure in the setting of adult respiratory distress syndrome. Case 2 was a 57-year-old woman known to have Rosai-Dorfman disease involving mediastinal lymph nodes and found to have a right atrial mass on workup for atypical chest pain. Both cases showed a similar histologic picture of large, multinucleated histiocytes with immunoreactivity to S100, emperipolesis, and marked plamacytosis. This study expands our knowledge of organs involved in extranodal Rosai-Dorfman disease.

Benign histiocytic proliferations are identified by their component cells and classified as either Langerhans cell histiocytosis or non-Langerhans cell histiocytosis. We report a 58-year-old Caucasian woman who presented with diabetes insipidus and was found to harbor a large suprasellar mass. Histopathological analysis was consistent with non-LCH. The differential diagnoses included juvenile xanthogranuloma, adult-onset xanthogranuloma, xanthoma disseminatum, Rosai-Dorfman disease, and Erdheim-Chester disease. Immunohistochemical examination demonstrated a proliferation of large lipid-laden histiocytic cells which were positive for CD68, negative for S100 protein, and showed only faint, background staining for CD1a. We present a case of an autopsy-confirmed non-Langerhans cell histiocytosis limited to the central nervous system and evaluated with both immunohistochemical and ultrastructural studies. Based on the multifocality, anatomic distribution, and immunostaining features, a diagnosis of Erdheim-Chester disease was made. This is only the second reported case of Erdheim-Chester disease with intracranial involvement but absence of extracerebral manifestations. Given the overlapping clinicopathologic, radiographic, and immunohistochemical profiles, differentiating between these rare histiocytic disorders can often present a significant diagnostic challenge. A systematic approach using all available clinical, laboratory, radiographic, histologic, immunohistochemical and ultrastructural data is essential for proper discrimination between the numerous histiocytoses.

Rosai-Dorfman disease (RDD) is a benign proliferative histiocytic disorder predominantly of the lymph nodes with extranodal involvement in some cases. However, serous membranes are seldom involved in the extranodal cases, and epicardial involvement is never reported. Most RDD cases show a self-limiting process with good prognosis and corticosteroid treatment in some patients exhibiting good effect. We recently observed a case of RDD primarily manifesting pericardial and bilateral pleural effusion that finally led to death, and corticosteroid treatment showed little effect. Autopsy showed the characteristic S100-positive and CD68-positive histiocytes exhibiting emperipolesis in the lungs, pleura, epicardium, mediastinal lymph nodes, and colon. This case illustrates the importance of RDD in the differential diagnosis of effusion in multiple serous cavities. The failure of corticosteroid therapy in this patient and her death showed the poor prognosis of some patients with RDD. Moreover, to our knowledge, epicardial involvement of RDD has not been reported.

Rosai-Dorfman Disease (RDD) is a rare benign disease characterized by sinus histiocytosis with massive lymphadenopathy. RDD can be differentiated from other types of histiocytosis by immunochemical analysis, as RDD is positive for S100. Conversely, toxoplasmosis lymphadenitis is characterized by clusters of epithelioid histiocytes in lymphoid tissue, with mixed lymphocytic and immunoblastic cell populations. The serology data could help in diagnosing toxoplasmosis lymphadenitis, as the toxoplasma IgG should be positive. Here we present the rare case of a 73-year-old woman who presented with a left parotid mass and multiple neck lymphadenopathy that initially had been diagnosed as toxoplasmosis lymphadenitis from a positive result on serology examination, but was finally proven to be RDD based on immunochemical results. We also discuss the relationship between RDD and toxoplasmosis in this case.

Rosai-Dorfman disease and Langerhans cell histiocytosis are both disorders of accessory immune cells. Two cases have been previously reported of concurrent Langerhans cell histiocytosis and Rosai-Dorfman disease. In this report, we characterize the findings and selected molecular studies in nine additional cases. Histology was reviewed. Immunohistochemical stains were performed on all cases in which slides or blocks were available. A combination of CD1a, S-100, CD3, CD20, langerin, CD68, CD163, CD21, CD35 and CD123 immunohistochemical stains were performed. High-resolution array comparative genomic hybridization was performed on six samples from five cases. In these cases, seven were female and two male, with an average age of 25 years (15 months-59 years). A majority of the cases were identified in lymph node. Areas of Langerhans cell histiocytosis had a typical appearance with the existence of bland 'coffee-bean' nuclei, clear cytoplasm and associated eosinophils. The immunophenotype was typical, including expression of CD1a, S100, CD68 and langerin. In areas of Rosai-Dorfman disease, there was emperipolesis seen in all cases. Cells were intermediate-large in size with large round nuclei and ample clear or pale cytoplasm. The lesional cells were positive for S100, CD68, CD163, without expression of langerin or CD1a. Array comparative genomic hybridization showed gains and/or losses in four of the six samples. One case showed no gains or losses and one additional case showed gains and losses in the Langerhans cell histiocytosis, while no abnormalities were discovered in the Rosai-Dorfman disease component. These findings are comparable to those seen in previous studies of Langerhans cell histiocytosis. We report the clinical and pathologic findings of the combination of Langerhans cell histiocytosis and Rosai-Dorfman disease. Furthermore, we suggest on the basis of evidence from our cases that, when simultaneous, the two entities may be pathophysiologically related.

Soft tissue Rosai-Dorfman disease (STRDD) is rare, previously reported only as single cases and few series. Simian virus 40 (SV40), a polyomavirus, has been identified in lymphoid processes and has a controversial role in neoplasia etiology. Occasional cytoplasmic pink granular inclusions and nuclear changes led us to explore a viral etiology. Only unpublished STRDD from our files with adequate material, soft tissue location, and diagnostic confirmation were included. Immunohistochemistry and follow-up were obtained. Eighteen STRDD patients, 4 male and 14 female, had 29 lesions; 5 with 2 or more lesions. Ages ranged from 8 to 81 years (mean 42.6 years and median 42.5 years). Soft tissue Rosai-Dorfman disease locations include trunk or proximal extremity (n = 19), distal extremity (n = 5), "abdominal" (n = 3), face (n = 1), and unknown subcutaneous site (n = 1). Sizes ranged from 0.5 to 13.7 cm (median, 2.4 cm). Previous disease included lymphoma, buttocks injection site, diabetes and hypothyroidism, and radiation for chronic dermopathy. No patients had a preceding or concurrent known viral infection; none had lymphadenopathy at present. None were known to be immunocompromised. Soft tissue Rosai-Dorfman disease was rapidly progressing. Initial pathologic diagnosis ranged from Rosai-Dorfman disease or inflammatory pseudotumor to inflammatory malignant fibrous histiocytoma. Grossly STRDDs were multilobulated, tan-yellow, and firm; morphologically, circumscribed, and subcutaneous-based. All had sheets of polygonal histiocytes with abundant pale eosinophilic cytoplasm, emperipolesis, plasma cells, and lymphocytes scattered and within clusters. Focal spindle cell change and mild pleomorphism were each observed in 3 patients; 2 had focal necrosis, none with mitoses. Small granular pink cytoplasmic inclusions and nuclear viral-like changes were observed. By immunohistochemistry, all STRDDs were positive for S100 protein, negative for CD1a, Epstein-Barr virus, and latent membrane protein, yet 3 (all abdominal, 1 multicentric) of the 9 studied were focally positive for cytoplasmic and nuclear SV40 polyomavirus. All were treated by local excision. Follow-up on 14 patients older than 8 to 16 years revealed recurrence in 3 patients with persistent multiple lesions, one with abdominal location. There were no metastases or death from disease. Soft tissue Rosai-Dorfman disease is a rapidly evolving, mostly solitary and nonrecurrent trunk and proximal extremity subcutaneous lesion in middle-aged females. More than one third can have persistent multicentric disease. It is important to recognize STRDD, to separate it from malignancy. Epstein-Barr virus/latent membrane protein was negative but polyomavirus was positive in 3 patients with abdominal STRDD, one with multicentric persistent disease. The relationship of polyomavirus to the evolution of abdominal STRDD should be further explored.
