Hepatic actinomycosis diagnosed by fine needle aspiration. A case report.

A 43-year-old woman, a long-term intrauterine contraceptive device (IUD) wearer with a history of Actinomyces organisms seen in cervicovaginal smears, developed hepatic actinomycosis 13 months after removal of the IUD. The liver involvement was diagnosed by fine needle aspiration (FNA) cytology and the use of immunocytochemical techniques. Histopathologic examination of a right pelvic mass removed at surgical exploration revealed an Actinomyces tuboovarian abscess, the primary lesion in this case. The importance of cytologic detection of Actinomyces in cervicovaginal smears for the prevention of IUD-related pelvic inflammatory disease (PID) is discussed, as is the usefulness of FNA cytology in the diagnosis of systemic actinomycosis.
