Abstract

Leiomyoma of the breast parenchyma proper is a rare neoplasm. This tumor occurs predominantly in late middle-aged women and can be clinically difficult to discern from carcinoma. Mammographically, the tumor lacks typical features of carcinoma, but this possibility cannot be absolutely excluded. Immunohistochemical, ultrastructural, and DNA characteristics are reported in a new case. Mammographic findings are reported for the first time. Immunoperoxidase findings with antibodies to muscle-specific actin, desmin, vimentin, S-100 protein, and cytokeratins, as well as the ultrastructural features, suggest a pure smooth muscle cell origin and not a myoepithelial cell origin.

    Citation Excerpt :

    Leiomyomas form slowly growing masses and are usually superficial and found near the nipple (Figure 10) although can be located more deeply. Superficial tumours probably derive from the smooth muscle of the nipple whilst those found more deeply may derive from myofibroblasts, myoepithelium, blood vessels or mesenchymal precursor cells.42 Microscopically, leiomyomas are circumscribed proliferations composed of bland spindle cells with cigar shaped nuclei and eosinophilic cytoplasm which form short, tightly interlacing fascicles.

    Most are superficial and near the nipple, but deep parenchymal tumors have been reported.34–44,107,108 Whereas superficial tumors likely derive from smooth muscle of the nipple, the origin of parenchymal leiomyomas is not clear, with possibilities including mesenchymal progenitor cells, blood vessels, myofibroblasts, and myoepithelium.35,44 Most present as palpable nodules without specific imaging features.35–37,40
