Metastasis of one tumor to another is an intriguing and rare phenomenon. Lung and breast malignancies are common donor tumors, while renal cell carcinoma and meningioma serve as frequent recipients. We report a case of malignant carcinoid of the ileum with metastasis to adenocarcinoma of the ovary. Histologic examination of the ovary showed a clear dimorphic pattern consisting of uniform polygonal cells arranged in an insular pattern and highly pleomorphic epithelioid cells forming small glands or solid nests. Immunocytochemical studies firmly established the distinct identity of the two tumors.
