Popis: Myopericytoma (MPC) is a rare benign mesenchymal neoplasm with perivascular myoid differentiation that most commonly arises in middle adulthood. The lesion generally involves the subcutaneous soft tissue of the lower extremities. Histologically, it is characterised by concentric perivascular proliferation of spindled myoid cells with bland elongated nuclei associated with blood vessels. The present case series emphasises five cases of MPC in relatively younger-aged female patients. Fine Needle Aspiration Cytology (FNAC) was inconclusive in all five patients. Histopathological examination showed perivascular concentric proliferation of myoid tumour cells, which were ovoid, spindled, or round cells with abundant eosinophilic cytoplasm, and no nuclear atypia, hyperchromasia, or necrosis. Immunohistochemistry (IHC) was positive for Smooth Muscle Actin (SMA). Although MPC can be diagnosed through histopathological examination, IHC is required for confirmation.
