Pulmonary IgG4+ Rosai-Dorfman disease

Abstract: Rosai-Dorfman disease (RDD) is a rare non-malignant proliferation of histiocytes of unknown aetiology that mainly affects lymph nodes. Here we report a case of RDD that presented a diagnostic dilemma due to its atypical presentation and the overlap with IgG4 disease. Our case presented with interstitial lung involvement without lymphadenopathy. Open lung biopsy suggested the diagnosis of RDD. However, the predominant IgG4 positive plasma cells together with the absence of lymphadenopathy were not typical of RD… Show more

“…Rosai–Dorfman disease is a rare chronic systemic non‐Langerhans cell histiocytosis. Although Rosai–Dorfman disease can present with increased IgG4‐positive plasma cells and can even be coincidental with IgG4‐related skin disease; consistent and unique histopathologic and immunohistochemical findings in the skin make their distinction from IgG4‐related skin disease straightforward. For example, while histiocytes can be observed in cutaneous IgG4‐RD, they are negative for S‐100, and emperipolesis is not observed, as was the case for the patient described at our institution (Fig.…”

“…His identical twin brother carries a diagnosis of Rosai-Dorfman disease, a histiocytic disorder characterized by S100 + and CD68 + histiocytes with intact lymphocytes within their cytoplasm (emperipolesis). Interestingly Rosai-Dorfman disease has also shown overlap with IgG4-RD [14] , [15] , [16] .…”

“…При ИГХ-исследовании гистиоциты положительны к CD11c, CD14, CD15, CD68, CD163 и α 1 -антихимотрипсину, но отрицательны к CD1a и лангерину [28]. В отличие от синусного гистиоцитоза в клетках образования отмечается экспрессия S100 [29].…”

“…Смертность наблюдается в 7% случаев болезни Розаи-Дорфмана, однако описаны и случаи спонтанной регрессии заболевания [27]. В отличие от других локализаций поражение легких при болезни Розаи-Дорфмана характеризуется плохим прогнозом, больные умирают в 1 / 3 наблюдений [28].…”
