carcinoma is a well-demarcated verrucous
squamous proliferation with bulbous rete ridges that push, rather than infiltrate, into the underlying stroma (Figure 3, A).
Three different histological patterns have been described based on the histological architecture and morphology of the lesion: verrucous
or warty (A), papillary or cauliflower (B), and flat (C) or slightly raised .

The same observation was made when comparing malignant tumours with either benign tumours (i.e., thyroid carcinomas versus follicular adenoma, mucoepidermoid carcinoma versus pleomorphic adenoma) [97, 100] or premalignant lesions (OSCCs versus dysplasia, verrucous
carcinoma versus verrucous
hyperplasia or verrucous
borderline lesions) [69, 70], in which HuR staining pattern has been proposed as an additional diagnostic tool.
(a) An area of verrucous
squamous cell carcinoma, connected to a high-grade squamous cell carcinoma, identified on the inner surface of the calyceal diverticulum.
The first manifestations appear in the early days of life as progressive to four stages: vesicular, verrucous
, and hyperpigmented, and hypopigmented lesions.
Extensive surgical resections may be performed in patients with laryngeal verruca vulgaris because it can be confused clinically with verrucous
Most common subtype is the conventional squamous cell carcinoma, accounting for 90% of the cases, while other relatively common types are Verrucous
carcinoma, Papillary squamous cell carcinoma, Basaloid squamous cell carcinoma, Acantholytic squamous cell carcinoma, Spindle cell carcinoma and Adenosquamous carcinoma.7
Secondary findings to leukemic infiltration are described, and an uncommon and excessive expression of verrucous
carcinomas can be observed.
