  1. Dermatology: Xanthelasma

    show more
    Description: Stomach-xanthelasma A papule, nodule, or plaque in the skin due to lipid deposits; it is usually yellow, but may be brown, reddish, or cream colored. Microscopically, the lesions show light cells with foamy protoplasm (foam cells). Xanthomas range in size from tiny pinheads to large nodules, and the shape may be round, flat, or irregular. They are often found around the eyes, the joints, the neck or the palms, or over tendons. Often these lipid deposits are not limited to the skin but are found throughout the body in bones, the heart, blood vessels, liver, and other organs.

  2. 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.

  4. Dermatology: Basal Cell Carcinoma

    show more
    Description: A malignant skin neoplasm that seldom metastasizes but has potentialities for local invasion and destruction. Clinically it is divided into types: nodular, cicatricial, morphaic, and erythematoid (pagetoid). They develop on hair-bearing skin, most commonly on sun-exposed areas. Approximately 85% are found on the head and neck area and the remaining 15% on the trunk and limbs. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1471)

    Description: A rare malignant neoplasm characterized by rapidly proliferating, extensively infiltrating, anaplastic cells derived from blood vessels and lining irregular blood-filled or lumpy spaces. (Stedman, 25th ed) This example occurred on the leg, and was taken after three weeks of growth

  10. Dermatology: Vitiligo Vulgaris

    show more
    Description: Vitiligo - depigmented patches over lips Vitiligo is a common, often inherited disorder characterized by areas of well-defined, milky white skin. People with vitiligo may have eye abnormalities and also have a higher incidence of thyroid disease, diabetes mellitus, and pernicious anemia. Vitiligo affects about 1-2% of the world's population. It is more easily observed in sun-exposed areas of the body and in darker skin types, but it affects any area of the body and all races. Vitiligo seems to affect men and women equally, although women more frequently seek treatment for the disorder. Vitiligo may appear as one or two well-defined white patches or it may appear over large portions of the body. Typical sites for generalized vitiligo are areas surrounding body openings, bony areas, fingers, and toes. It can begin at any age but about 50% of the time it starts before the age of 20.
