Despite well-defined clinical and histopathological features of melanoma, atypical presentations mimicking other skin disorders can result in a delayed diagnosis or misdiagnosis and subsequent inappropriate treatment. Rosai-Dorfman disease (RDD) is a rare histiocytic disorder with unique clinical and histopathological features. We report a case of melanoma treated with cryotherapy that mimicked RDD both clinically and histopathologically. We compare this RDD-like melanoma to classic RDD, outlining the importance of clinicopathological correlation prior to treatment, as well as the potential pitfalls in diagnosis after cryotherapy of pigmented lesions.

Langerhans cell histiocytosis (LCH), juvenile xanthogranuloma (JXG) family lesions, and Rosai-Dorfman-Destombes disease (RDD) are now classified by the World Health Organization (WHO) under the heading of histiocytic/dendritic cell neoplasms. Each disease may manifest as a focal lesion, as multiple lesions, or as a widespread aggressive systemic disease with visceral organ involvement. Erdheim-Chester disease (ECD) is a rare systemic disease process of adults with limited cases in children.

Rosai-Dorfman disease (RDD) is a self-limited, idiopathic, non-neoplastic disorder characterized by the proliferation of phagocytic histiocytes, which can mimic malignant lymphoproliferative disease. Cases of RDD most commonly present as bilateral painless cervical lymphadenopathy, with lesser involvement of the axilla, inguinal, and mediastinal lymph nodes. We present the case of a 62-year-old woman with a history of endometrial serous carcinoma who underwent evaluation at a dedicated breast imaging department after positron emission tomography/computed tomography (PET/CT) revealed breast masses and axillary nodes with increased uptake of fluorodeoxyglucose (FDG).

Rosai-Dorfman disease (RDD) is a rare proliferative histiocytic disorder characterized by sinus histiocytosis with massive lymphadenopathy, rarely presenting with severe and life-threatening extra-nodal features. The rarity of RDD, clinically variant phenotype, limited data, and lack of a current standardized management approach make treatment decisions difficult. Herein, we present a case of life-threatening, disseminated RDD with rare clinical features of recurrent pericardial effusion, bilateral pleural effusions, and abdominal tissue fibrosis successfully treated with six cycles of cladribine, achieving clinical remission.
