“…HPV DNA expression is reported in some case reports; but could not be detected in others (Leao, Batista, Guimaraes, Belo, & Porter, 2005;Stierman, Chen, Nuovo, & Thomas, 2010). In a recent study, the histopathological features of nine CD-related oral lesions were analyzed in detail and presence of koilocytosis, acanthosis, and papillomatosis was reported in all samples (Hammerschmidt, Lourenco, & Nico, 2017). The proposed diagnostic criteria of National Comprehensive Cancer Center (NCCN) for CD includes mucocutaneous lesions as a major criterion including at least one biopsy-proven trichilemmoma, multiple palmoplantar keratoses, multifocal or extensive oral mucosal papillomatosis and multiple facial papules and does not involve viral warts ("The NCCN 3.2019, NCCN genetic/familial high-risk assessment: Breast and ovary, Cowden syndrome, clinical practice guidelines in oncology").…”
