  3. Dermatology: Warfarin-induced Skin Necrosis, Fatal, Breast

    show more
    Description: Fatal skin necrosis at breast, induced by heparin. Skin necrosis is the pathologic death of one or more cells, or of a portion of tissue or organ, resulting from irreversible damage; earliest irreversible changesare mitochondrial, consisting of swelling and granular calcium deposits seen by electron microscopy; most frequent visible alterationsare nuclear: pyknosis, shrunken and abnormally dark basophilic staining; karyolysis, swollen and abnormally pale basophilic staining;or karyorrhexis, rupture, and fragmentation of the nucleus. After such changes, the outlines of individual cells are indistinct, andaffected cells may merge, sometimes forming a focus of coarsely granular, amorphous, or hyaline material.

  5. Tube Granuloma, Tympanic Membrane, Image 4

    show more
    Description: Tympanic membrane - Tube granuloma 4 By definition, a granuloma is a nodular inflammatory lesion. They are usually small and consist primarily of compact mononuclear phagocytes. Granulomas are different from other inflammatory reactions; they represent an ultimately unsuccessful localized attempt to rid the host of an offending organism or process. Granulomatous diseases in the middle ear may be localized primarily to the ear and surrounding tissues, or they may be a manifestation of a body-wide disseminated problem.
