A Clinical Atlas of 101 Common Skin Diseases
Second Edition. Philip E. LeBoit, MD, Brian Hinds, MD, editors
This clinical atlas features more than 3,000 color photographs and 200 photomicrographs. Accompanying text covers relevant diagnostic tests, therapeutic considerations, the clinical course, and unifying concepts
Papules, nodules, and tumors that, on gross examination, are usually skin colored and, on histopathologic examination, consist of an epithelium-lined sac that contains fluid, cells, or both in the case of true cysts and of cysts that are associated with other epithelial elements of adnexa in the case of cystic hamartomas.
Extramammary Paget’s disease is an apocrine carcinoma that begins within the epidermis and presents itself clinically as a patch or a subtle plaque that extends centrifugally for many years before becoming a readily discernible thick plaque, a finding that signifies involvement by the carcinoma of the dermis, too.
A proliferation of abnormal Langerhans cells that may affect internal organs, e.g., the spleen, liver, and bone, sometimes with fatal outcome, as well as the skin, where lesions usually manifest themselves as purpuric papules or ulcers that may be localized (to the vulva, for example) or widespread.
Noninflammatory scaly disorders in which polygonal gray or brown scales tend to be elevated at their periphery, causing them to appear to be separated from contiguous scales, findings that are seen in three conditions, namely, ichthyosis vulgaris (and its look-alike, acquired ichthyosis), X-linked ichthyosis, and lamellar ichthyosis.
Keratotic spikes that emerge from dilated ostia of infundibula and are equidistant from one another. The term keratosis pilaris refers to the phenomenon when it presents itself without any distinct arrangement of individual lesions, whereas the designation lichen spinulosus is applied to the same lesions when they are arranged in a circle.
Hamartomas (“congenital” melanocytic nevi) and benign neoplasms (“acquired” melanocytic nevi) of various specific types, all of which are composed of abnormal melanocytes and manifested clinically as lesions of different colors, shapes, and sizes, among them, macules and patches, papules and plaques, and nodules and tumors.
An inflammatory process, but not a vasculitis, that involves the legs especially with purpuric macules and subtle papules (Schamberg’s disease), lichenoid papules (lichenoid purpura of Gougerot-Blum), and scaly papules (eczematid-like purpura of Doucas and Kapetanakis), all of which seem to be variants of the same basic pathologic process.
A benign neoplasm of apocrine ductal nature within the upper half of the dermis that manifests itself clinically as tiny, smooth, skin-colored, round or oblong papules that usually are situated in periorbital skin, but may be seen on other sites, such as the neck or genitalia, or even be widespread.
An inflammatory process caused by Mycobacterium tuberculosis. In the skin, it may be primary as a consequence of direct inoculation (tuberculosis verrucosa cutis) or secondary to a focus of tuberculosis in another organ (the lung for lupus vulgaris, and bones, as well as lymph nodes, for scrofuloderma).
