    Notes: Summary The chondroid areas of 11 mixed mammary gland tumours taken from female dogs were studied by light and electron microscopy to determine the histogenesis of their cells. Their abundance of directed and periodically striated fibrils about 70 Å thick, their large fields of glycogen, their ability to form basal membranlike structures and the microscopically visible development suggested that the cells were neoplastic myoepithelial cells. The findings indicate that these neoplastic cells are able to produce the chondroid matrix as well as the material for the synthesis of collagen fibrils.

    Description / Table of Contents: Zusammenfassung Es wurden licht- und elektronenmikroskopisch Spindelzellen fischzugartiger Verbände in 19 Mammamisehtumoren von Hündinnen untersucht. Die elektronenmikroskopischen Befunde sprechen dafür, daß es sich bei den spindeligen Tumorzellen meist um Zellen myothelialen Ursprungs handelt. Es wurden jedoch auch spindelzellige Verbände gefunden, die aus Fibroblasten bzw. Pibrocyten bestehen. Im lichtmikroskopischen Bereich ist eine sichere Unterscheidung nicht in jedem Fall möglich.
    Notes: Summary Spindle cells of myomatous formations of 19 canine mixed mammary tumors were studied by light and electron microscopy. The EM findings indicate that the spindleshaped tumor cells are mostly of myoepithelial origin. However there were also formations of spindle cells which consisted of fibroblasts or fibrocytes. By light microscopy they are not always clearly distinguishable.

    Description / Table of Contents: Zusammenfassung Es werden die elektronenmikroskopischen Befunde an einem Mammamischtumor der Hündin mit dem Auftreten von sog. Oncocyten berichtet. Der Tumor besteht aus kleinen myxoiden Herden und drüsigen Formationen mit organoidem Aufbau. Die Drüsenwandungen sind aus peripher liegenden myothelial differenzierten Zellen und aus epithelialen Zellen aufgebaut. Letztere sind größtenteils oncocytär umgewandelt und zeichnen sich durch den massiven Besatz mit pathischen Mitochondrion aus. Die myxoiden Herde werden von myothelial differenzierten Zellen gebildet.
    Notes: Summary The electronmicroscopic findings of a canine mixed mammary gland tumour containing oncocytes, are described. The tumour consists of small myxoid foci and glandular formations with an organoid structure. The glandular walls are composed of myoepithelial differentiated cells and epithelial cells. Most of the latter are oncocytes and characterized by an extensive amount of pathic mitochondria. The myxoid foci consist of myoepithelial differentiated cells.
