A case of ancient neurilemoma (Schwannoma) is presented that, owing to a severe cell pleomorphism, was falsely interpreted as a malignant spindle‐cell sarcoma by fine‐needle aspiration cytology. Cytological features of the tumor are given together with its histopathology and electron microscopy findings. The usefulness of electron microscopy on material obtained by fine‐needle aspiration biopsies in the diagnosis of soft‐tissue tumors is discussed. Diagn Cytopathol 1986;2:244‐247.
