Inquiry Details
References:
ICD-O-3, 29. Rule F
Question:
Reportability: If a dermatopathologist refers to an atypical fibroxanthoma as a malignant process, but the ICD-O-3 indicates it is a borderline process, is this a reportable case? See Discussion.
Discussion:
"Final Diagnosis: Surface of ulcerated histologically malignant spindle cell neoplasm, consistent with atypical fibroxanthoma. Note: An exhaustive immunohistochemical work-up shows no melanocytic, epithelial or vascular differentiation. Atypical fibroxanthoma is a superficial form of a malignant fibrous histiocytoma."
Answer:
The pathologist has the final say on behavior. In this case, the pathologist states that this tumor is malignant in the final diagnosis. Therefore, this case is reportable.
