Nonbacterial thrombotic endocarditis in Hong Kong Chinese.
Fifty-two Hong Kong Chinese cases of nonbacterial thrombotic endocarditis at autopsy were reviewed to ascertain if there was any difference in autopsy incidence, associated diseases, age and sex incidence, distribution of infarcts, and pattern of valve involvement compared with that in previously reported series. The overall autopsy incidence was 0.68%, within the range of previous reports. Forty-one cases (79%) were associated with malignant neoplasms; the remaining 11 cases were associated with miscellaneous disorders. Adenocarcinoma was associated with 27 (52%) of the cases. Unusual findings were the association of five cases with intrahepatic cholangiocarcinoma and four cases with esophageal squamous carcinoma. This is explicable on the basis of a higher incidence of these two tumors in Hong Kong Chinese than in Western populations, ie, the source of most other reported series. Sex and age incidence, the distribution of infarcts, and the pattern of valve involvement were similar to those reported in other series of nonbacterial thrombotic endocarditis.
