Original contributionRosai-dorfman disease of the pleura: a rare extranodal presentation
Section snippets
Case report
The patient was an 81-year-old man of Mediterranean extract who presented with complaints of increasing shortness of breath. Computed tomography scan of the chest revealed a large loculated left-sided pleural effusion, parietal pleural thickening, complete collapse of the left lower lobe, and partial left upper-lobe atelectasis. There was no thickening involving the left visceral pleura, right pleura, or pericardium. The lungs contained multiple calcified nodules bilaterally, but no
Pathologic findings
The pleural biopsy specimen displayed thickening with fibrosis and diffuse infiltration by histiocytes, lymphocytes, and occasional neutrophils. These inflammatory cells dissected through the pleural collagen fibers and extended into the adipose tissue. The histiocytes were plump, with lightly eosinophilic cytoplasm and exhibited emperipolesis (Fig 1). Immunohistochemical analysis demonstrated positive reactivity of the characteristic histiocytes with S100 and CD68 antibodies (Fig 2).
Discussion
Rosai-Dorfman disease involving the thorax is rare and most often manifests as pulmonary disease, which accounts for only 2% of Rosai-Dorfman disease cases.2 The patients who develop pulmonary Rosai-Dorfman disease are young (average age, 14 years), have involvement of lymph nodes and other extranodal sites (nasal cavity, paranasal sinuses). The tracheobronchial tree is infiltrated most commonly, and intraluminal polypoid growth of Rosai-Dorfman disease may produce airway obstruction.2, 3, 4, 5

2016, ChestCitation Excerpt :Involvement of the larynx, lung, and pleura has been reported in only a few cases.13 Authors of a case report documenting the rare isolated involvement of pleura reported involvement of the lower respiratory tract by RDD to be relatively rare, comprising 3% of extranodal cases.14 Pulmonary RDD typically involves the tracheobronchial tree, with intraluminal polypoid lesions sometimes associated with airway obstruction.
Rosai-Dorfman disease of multiple organs, including the epicardium: An unusual case with poor prognosis
2011, Heart and Lung: Journal of Acute and Critical CareCitation Excerpt :Although the autopsy proved the involvement of pulmonary parenchyma, no obvious abnormalities were identified by CT scanning, possibly because the lesions were too tiny to be found. Ohori et al2 reported 1 case of RDD primarily limited in the pleura without pulmonary parenchymal involvement, which was confirmed by pleural biopsy;2 however, it is possible that there were also tiny lesions in the parenchyma that were missed during CT scanning. RDD involving the thorax is rare and often manifests as a pulmonary disease, which accounts for only 2% of RDD cases.6
Intrathoracic manifestations of Rosai-Dorfman disease
2010, Respiratory MedicineCitation Excerpt :When considering only individuals with lower respiratory tract involvement, 4 out of 21 patients were affected, representing a higher percentage and also a better prognosis than previously described. Case reports have been published on primary central airway involvement,9 and pleural involvement.7 In the current series, one patient had a pleural effusion.
Update on pulmonary and pleural lymphoproliferative disorders
2008, Diagnostic HistopathologyCitation Excerpt :Parenchymal involvement is less common.210 Ohori et al. reported a single case of Rosai–Dorfman disease presenting within the pleura.211 Histological features are similar to nodal and other extranodal-based cases and consist of a distinctive proliferation of large histiocytic cells variably admixed with lymphocytes, plasma cells and neutrophils.
