Question:
Reportability/Behavior--Kidney: Is epithelioid angiomyolipoma (AML) of the kidney a reportable malignancy? See Discussion.
Discussion:
The addendum final diagnosis on a pathology report for a kidney core needle biopsy included the results of additional stains performed on the tissue. It indicated the morphology was most consistent with epithelioid angiomyolipoma. Further comments in the body of the report indicate these tumors are now considered malignant neoplasms with the capacity to be locally aggressive and they can potentially metastasize. There is no mention of a metastasis in this particular case.
Answer:
Epithelioid angiomyolipoma (AML) [8860/0] of the kidney is not reportable unless stated to be malignant.
If the pathologist confirms this is a malignancy, apply ICD-O-3 Rule F (Matrix principle) and assign the behavior code /3. If confirmation is received, accession the case using the morphology code 8860/3 [malignant angiomyolipoma].
