The given image shows Verrcosa vulgaris.
Verruca vulgaris (common warts) are keratotic lesions caused by infection by various subtypes of the DNA virus, human papillomavirus (HPV)
Histopathologic examaniation of verruca vulgaris reveals a markedly and papillomatous epidermis with hypergranulomatosis and overlying tirs of parakeratosis.
The upper epidermis may contain large pink inclusions , particularly in cases arising on acral skin. Other lesions show smaller basophilic granules. Characteristic vacuolated keratinocytes (koilocytes), which have a small shrunken nucleus surrounded by a perinuclear halos, are seen in the upper epidermis.
