Aspiration biopsy cytology of mammary myoepithelioma

A case of ultrastructurally confirmed myoepithelioma of the breast studied by fine‐needle aspiration biopsy is reported. Aspirated tumor cells were spindle‐shaped with well‐defined cytoplasm and oval nuclei showing no remarkable nuclear pleomorphism. They were seen mainly in irregular bundles with strong cellular cohesiveness. Their cytoplasm contained S‐100 protein demonstrated by the peroxidase antiperoxidase staining technique.
