Inquiry Details
References:
ICD-O-3
Question:
Reportability--Brain and CNS: Is Rosai-Dorfman disease a neoplastic reportable disease process if it occurs in the brain? See Discussion.
Discussion:
The pathology report diagnosis is: Cranium, right temporal area, resection of intradural, extra-axial mass: Severe acute and chronic inflammation, histiocytic reaction, and proliferative fibrosis. See comment.
Comment: Among potential alternative considerations are an infectious process, or non-infectious inflammatory CNS lesions such as inflammatory pseudotumor, Rosai-Dorfman disease, plasma cell granuloma, idiopathic hypertrophic pachymeningitis, and inflammatory myofibroblastic tumor.
The clinicians discuss this and review other chart information and conclude the patient has a clinical diagnosis of Rosai-Dorfman disease.
This is a rare disorder characterized by proliferation of histiocytes.
Answer:
This case is not reportable. Rosai-Dorfman disease is not listed in the ICD-O-3. To be reportable, a neoplasm must be listed in the ICD-O-3 and originate in a reportable brain/CNS site.
