Olfactory neuroblastoma (esthesioneuroblastoma): Appearance on fine‐needle aspiration: Report of a case

Small round‐cell tumors can arise from several anatomic sites in children and adults, and their primary diagnosis and clinical course often present challenges to physicians. We present a case of a rare adult‐onset round‐cell tumor, esthesioneuroblastoma, of nasal epithelial origin, which spread into the brain and subsequently to cervical lymph nodes. The report describes how fine‐needle aspiration cytology identified the metastatic spread and contributed to its clinical management. The use of ancillary procedures in differential diagnosis of small round‐cell tumors is reviewed. Diagn. Cytopathol. 1997;17:205–208. © 1997 Wiley‐Liss, Inc.
