\nVerruca vulgaris (common warts) are keratotic<\/span> injuries caused by infection<\/span> by various subtypes of DNA<\/span> virus, human papillomavirus (HPV).<\/p>\n<\/span>\nHistology<\/span> vulgar wart<\/span><\/h2>\nHistopathological examination of the verruca vulgaris reveals a marked and papillomatous<\/span> epidermis<\/span> with hypergranulomatosis and overlapping levels of parakeratosis<\/span> (Figure 1).<\/p>\nThe upper epidermis may contain a large pink inclusions<\/span> (figure 2), particularly in cases that arise in acral<\/span> fur. Other injuries show less basophilic<\/span> granules<\/span> (figure 3). Characteristic vacuolated<\/span> keratinocytes<\/span> (koilocytes<\/span>), which have a little shrinkage core<\/span> surrounded by a perinuclear<\/span> halos, are seen in the upper epidermis (figure 3).<\/p>\n\n<\/span>Common wart pathology<\/span><\/h5>\n<\/section>\n\n\n

\n<\/span><\/h2>\nSeborrheic<\/span> keratosis<\/span> \u2013 The distinction may be difficult for old warts in which the viropathic effect is difficult to appreciate. Some pathologists use the term \u201cverrugal keratosis\u201d or similar in cases where a clear distinction cannot be made.<\/p>\nMolluscum contagiosum: The large viral inclusions of the mollusk should not be confused with the large basophilic inclusions that can be seen in some warts (Figure 2). Large HPV inclusions are usually seen in lesions that occur in the acral skin, an extremely rare site for molluscum contagiosum.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"
