Spindle‐cell rhabdomyosarcoma (RMS) is a relatively recently recognized favorable variant of embryonal RMS occurring mainly in the paratesticular and head and neck regions. Cytological reports of spindle‐cell RMS have been sparse in the literature and the awareness of its cytological features is not very wide among cytopathologists. A 2‐year‐old girl was brought to clinical attention for a progressively enlarging swelling of right thumb. Imaging studies showed it to be a soft‐tissue tumor in the subcutaneous region. Fine‐needle aspiration yielded moderately cellular smears composed of small, round cells and few spindle cells with tapered cytoplasm. A cytological impression of RMS was rendered, which was later confirmed as spindle‐cell RMS on excision biopsy. Spindle‐cell RMS, a favorable prognostic variant of embryonal RMS, should be considered in the cytologic diagnosis of soft‐tissue tumors with round cell and spindle cell morphology. This is especially true for tumors occurring in hitherto unreported sites. Diagn. Cytopathol. 2016;44:1094–1097. © 2016 Wiley Periodicals, Inc.
