[Autopsy case of simultaneous triple malignancies--ovarian, chordoma and thyroid cancers].

A 53-year-old woman was admitted to our hospital because of genital bleeding. The clinical diagnosis was cancer of the corpus uteri with much ascites. During the course of 10 months of illness, she complained of low back pain, so we diagnosed the sacral metastasis by scintigram. Autopsy examination revealed simultaneous triple malignancies of the right ovarian cancer, the sacrococcygeal chordoma, and the thyroid cancer. Histologically, the ovarian cancer was papillary cystadenocarcinoma with widespread metastases. The chordoma invaded the bone marrow of the sacrum. The thyroid cancer was follicular carcinoma without metastasis. This combination is very rare.
