Rosai-Dorfman disease is a rare histiocytic disorder, clinically characterized by massive, bilateral painless cervical lymphadenopathy with potential for extranodal manifestations. We report a 45-year-old male patient who presented with a slowly growing erythematous nodule of the left chin. The mass appeared non-vascular on computed tomography study, but ultrasonogram was suggestive of a vascular lesion. The lesion was excised with presumptive diagnosis of a hemangioma. However, histopathologic examination of the surgical biopsy revealed histiocytic infiltration with emperipolesis, which was pathognomic for Rosai-Dorfman disease. Additional imaging studies did not reveal lymph node enlargement or other extranodal manifestation. The patient was diagnosed with cutaneous form of the Rosai-Dorfman disease and was discharged home. He remains free of local recurrence at 8 months.

Rosai-Dorfman disease is a rare disorder of unknown of etiology and is usually associated with benign proliferation of hematopoietic and fibrous tissue that often manifest in the head and neck region. We report a case of extranodal Rosai-Dorfman disease presenting in the neck, subglottis and nasal floor diagnosed by voice change.

Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease(RDD) is a rare type of histiocytosis syndrome, that presents in its most typical form as massive, painless, bilateral lymph node enlargement in the neck during the first or second decade of life. The disease involves extranodal site in over 25% to 43% of the cases, however cases of extranodal RDD without nodal disease have rarely been reported. The involved sites of extranodal RDD have been reported various that were orbit, ocular adnexae, head and neck, upper respiratory tract, breast, gastrointestinal tract, CNS, etc. A 35 year-old man was present with pleural pain on left anterior chest and anterior mediastinal mass, that underwent an excision to remove the suspected invasive thymoma, and the diagnosis was confirmed to extranodal Rosai-Dorfman disease.

Rosai-Dorfman disease (RDD) is an idiopathic histioproliferative disorder of lymph node and extranodal site. Bone involvement is very rare. We report a case of extranodal RDD of the tibia in 32-year old male. The patient presented with pain with no evidence of lymphadenopathy. Clinico-radiologic diagnosis was metastatic carcinoma or Langerhans cell histiocytosis, but, histopathologic examination confirmed the diagnosis with RDD. We performed curettage on the osteolytic lesion of tibia. In South Korea, there was no report about RDD of the extremity and we want to report this case with review of the literature.

Rosai-Dorfman Disease (RDD) is a rare lymphoproliferative disease, and the occurrence of isolated intracranial RDD is extremely rare. Most cases of intracranial RDDs present as dural masses showing homogenous enhancement on MRI, which makes it difficult to differentiate these masses from meningiomas before surgery unless massive cervical lymphadenopathy is observed. We herein report a rare case of isolated intracranial RDD in a 65-year-old male. Brain MRI revealed a well-defined enhancing mass-like lesion involving the right frontal convexity and subtle diffusion restriction. However, only a subtle blush was observed on the preoperative cerebral angiogram. Although instances of isolated intracranial RDD are rare, it should be considered as a potential differential diagnosis when a dural mass with hypovascularity is visualized on the cerebral angiogram.

Rosai-Dorfman Disease[RDD] is an idiopathic histiocytic proliferation affecting lymph nodes. Although extranodal involvement has been reported in the skin, orbit, upper respiratory tract, of testes, the isolated intracranical involvement without associated lymphadenopathy is extremely rare. We report our experience with 1 case of an isolated intracranial RDD without associated lymphadenopathy and any other organ involvement. A 61-year-old male presented with an isolated well-circumscribed brain mass in the posterior fossa, preoperatively thought to be a meningioma. But histology and Immunohistochemistry confirmed that the lesion was RDD.

Rosai-Dorfman disease (RDD) is a benign proliferative histiocytic disorder of unknown etiology, which typically manifests as lymphadenopathy and systemic symptoms. Lymph node involvement is typical, but soft tissue RDD without nodal or systemic involvement is extremely rare. We report on a case of soft tissue RDD in a 16-year-old girl with a palpable mass on her buttock. It was firm, mobile, and discrete without tenderness. Excisional biopsy was performed, then RDD was confirmed histologically. RDD is a non-neo-plastic disease that should be considered in the differential diagnosis of other soft tissue tumors. While the optimal treatment for extranodal RDD remains controversial, surgical excision is typically curative.
