* Tumor-to-tumor metastasis is a rare phenomenon. Renal cell carcinoma is the most common recipient of tumor-totumor metastasis in malignant tumors. However, renal angiomyolipoma has not been reported to be a recipient. Here we report 2 cases of tumor-to-tumor metastasis to renal angiomyolipoma. In one case, the donor tumor originated from neuroendocrine carcinoma of the pancreas, and in the other case the donor tumor was from adenocarcinoma of the lung. The donor tumors showed morphologic features that did not easily fit into renal angiomyolipoma, and they also demonstrated patterns of immunoreactivity consistent with the primary tumors rather than with renal angiomyolipoma.
