Some architectural differences are reported on otherwise similar lesions, which include two cases with marked verruciform
architecture and three cases of a reticulated pattern with elongated strands of keratinocytes (8-11).
2) Patients are predominantly middle-aged and female, and they present with erythematous verruciform
plaques (Figure 3, A) on sun-damaged skin of the face, arms, and, less commonly, the chest.
The typical lesion of OVV may be identical to a squamous papilloma, but it tends to have pointed or verruciform
surface projections, have a very narrow stalk, are white due to considerable surface keratin, and present as multiple or clustered individual lesions.
3] The verruciform carcinomas of the penis are a heterogeneous group of exophytic, generally low-grade SCC.
Recently, Barreto and colleagues have described a distinct variant of penile verruciform tumours that show an endophytic, deeply burrowing, branching phenotype previously described as carcinoma cuniculatum.
Histopathologically, the lesion was nodular and verruciform with an invasive endophytic growth pattern.
The low-risk group includes verruciform tumors such as verrucous, papillary, and warty/condylomatous carcinomas.
In larger tumors, especially verruciform ones, the previously mentioned system is not applicable, and we measure the thickness from the surface (excluding the keratin layer) to the deepest point of invasion.
or papillomatous PEH is difficult to separate diagnostically from verrucous squamous carcinoma.
