In this report, we describe a case of ectopic cervical thymoma (medullary or type A thymoma, according to the WHO classification) located in the anterior cervical region (thyroid topography) that was submitted to ultrasound‐guided fine‐needle aspiration biopsy. The cytologic smears were moderately cellular to very cellular and were composed of numerous spindle‐shaped cells placed predominantly in tissue fragments, with no specific arrangement. Isolated spindle‐shaped cells were also present in a hemorrhagic background. The nuclei were elongated with finely granular chromatin and inconspicuous nucleoli. Mitosis, nuclear atypia, and necrosis were not detected. There was a scarce lymphoid population of small lymphocytes. The cytologic aspects, the correlation with histologic findings, and the differential cytologic diagnosis are reviewed. Diagn. Cytopathol. 2005;32:358–362. © 2005 Wiley‐Liss, Inc.
