case_images: Physical examination revealed a 2.5 cm pedunculated, cauliflower-like mass with a verrucous surface on the left side of the vulva (Fig. 1).
case_images: (a) A papillomatous pattern with hyperkeratosis, parakeratosis and acanthosis (haematoxylin and eosin; original magnification: x 40). Round and tapering dermal papillae with a fibrovascular core (x100). (b) Invasion of the dermis by irregularly shaped, jagged nests of epithelium, the cells which are predominantly mature squamous cells showing atypicality (haematoxylin and eosin; original magnification: x50). The invading tumor masses are composed of atypical squamous cells (x 200). (c) Cells within the tumor nest demonstrate koilocytosis with large, wrinkled, hyperchromatic nuclei, and horn pearl is present (haematoxylin and eosin; original magnification: x400).

case_images: The dermal papillae had round or tapering, pointed ("spiked") tips, and a central thin fibrovascular core (Fig. 2a). The dermis showed a marked inflammatory reaction (Fig. 2b).
