Orbital ectopic lacrimal gland tissue simulating a neoplasm. Report of a case with fine needle aspiration biopsy diagnosis.
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.
Juvenile pilocytic astrocytoma of the optic nerve diagnosed by fine needle aspiration biopsy.
Fine needle aspiration biopsy of an orbital mass was performed under CT guidance in a nine-year-old boy presenting with rapidly increasing proptosis of the right eye with lateral displacement and no light perception. The cytologic findings consisted of bipolar astrocytes with cytoplasmic fibrillated processes intermingled with Rosenthal fibers. A cytologic diagnosis of juvenile pilocytic astrocytoma was advanced; this was confirmed by subsequent histologic study of the surgical specimen. The differential diagnosis among juvenile pilocytic astrocytoma, neurilemmoma and meningioma of the optic nerve are discussed.
