The detailed light and electron microscopic and immunohistological features of an invasive apocrine carcinoma of the breast developing in a 78-year-old woman are presented. The stroma of the tumour contained non-neoplastic lipid-filled (foam) cells. To our knowledge, these cells have not been described before in invasive breast carcinoma. Their electron microscopic and immunohistological features confirm their histiocytic nature.
