Additionally, amianthoid fibres and fuchsinophilic bodies are present. Immunohistochemical analysis typically was positive for SMA and cyclin D1, with a low proliferative index (Ki67 of <1%). The diagnosis was intranodal palisading myofibroblastoma. Only two cases of IPM in the axilla have been previously reported.
