Histology and cytology of malignant PEComa. (a) Sheets of polygonal epithelial cells with hyperchromatic nuclei with prominent nucleoli and brisk mitotic activity (H&E, 400x). (b) Epithelioid cell clusters in a hemorrhagic background (Papanicolaou stain, 400x). (c) Medium cellular aspirate in hemorrhagic background (Papanicolaou stain, 400x). (d) Pleomorphic cells with enlarged nuclei with conspicuous nucleoli and light eosinophilic cytoplasm (Papanicolaou stain with oil, 1000x).
