title: Orbital ectopic lacrimal gland tissue simulating a neoplasm. Report of a case with fine needle aspiration biopsy diagnosis.
abstract: A case occurred of sclerosing chronic dacryoadenitis in lobules of ectopic lacrimal gland tissue diagnosed by fine needle aspiration biopsy performed under computed tomographic guidance. This choristomatous lesion caused unilateral proptosis and clinically simulated a neoplasm. This is the first report of cytologic diagnosis of orbital ectopic lacrimal gland tissue using fine needle aspiration biopsy. The potential hazard of regarding glandular inclusions derived from inadvertent use of a needle on a normal lacrimal gland or glands as indicating metastatic neoplasms is stressed.
