Leiomyoblastomas are rare tumors, and there have been few reports on their fine‐needle aspiration (FNA)cytologic morphology. We herein describe the FNA features of a gastric leiomyoblastoma with subcutaneous metastasis. The cells had eosinophilic cytoplasm and oval eccentric nuclei, occasionally with intranuclear cytoplasmic inclusions. An organoid pattern was obvious in cell block sections. The tumor was positive for vimentin but negative for desmin, S‐100 protein, and the common epithelial markers. The histogenesis is discussed, as are reasons why this tumor is better termed epithelioid mesenchymal tumor.
