The total number of oral
verruciform xanthomas with concomitant lichen planus reported in the literature including the present case amounts to twelve.
Histological examination of PP characteristically shows psoriasiform hyperplasia and multiple cornoid lamellae, which probably result in the hyperkeratotic and/or
verruciform nature of the plaques and also distinguish it from other forms of PK.

verruciform growth in the upper esophagus in an elderly patient with a history of radiation exposure [12].
Different histological groups of penile neoplasms with an exophytic papillary lesions including WC are collectively referred to as the "
verruciform" group of neoplasms [2,12].
(8) The clinical types of leukoplakia are (1) homogeneous (2) ulcerated (3) ulcerated with pigmentation (3) nodular (4) speckled and (5)
verruciform. (1)
The squamous papillomas are benign, very common (2.5-3% of all oral biopsies) epithelial proliferations most caused by HPV (subtypes 2, 6, 11), resulting in papillary or
verruciform lesions.
Other histological patterns are papillary, insular,
verruciform as well as spindle cell type.
Setting the diagnosis of FEH is important to ensure differential diagnosis from other more serious conditions including inflammatory fibrous hyperplasia, inflammatory papillary hyperplasia,
verruciform xanthoma, verrucous carcinoma, condyloma acuminatum, Cowden's Syndrome, Crohn's disease, and Amyloidosis.

verruciform xanthoma: ten cases associated with lichen sclerosus, Lichen Planus, or other conditions," Archives of Dermatology, vol.
Penile cancer is predominantly of squamous cell histology (95%) with several subtypes, including verrucous carcinoma, basaloid carcinoma, warty carcinoma (
verruciform), and neuroendocrine carcinoma.
It is widely assumed that the Human papilloma Virus (HPV) is an etiologic factor of papillomas.1 The lesion may look wart-like or cauliflower like and may be difficult to differentiate clinically from verruca vul- garis, condyloma acuminatum,
verruciform xanthoma or focal epithelial hyperplasia.2,3
