Verrucous carcinoma, first described by Ackerman 1 in 1948, is an uncommon, low-grade, well-differentiated variant of squamous cell carcinoma. It presents as a slow-growing, bulky, exophytic tumor with a broad base. The tumor can ulcerate or present with …

There was a papillomatous lesion on the right lateral tongue with no induration ( Fig.1). The punch biopsy was performed and the biopsy speci- men was reported

However, they should usually be removed surgically by formal excision or shave, curettage and cautery as it is not possible to determine which lesions will resolve. Histologically, clinically diagnosed keratoacanthomas often prove to be well differentiated squamous cell carcinoma. Keratoacanthoma is a common low-grade rapidly-growing skin tumour that is believed to originate from the hair follicle and can resemble squamous cell carcinoma. The defining characteristic of a keratoacanthoma is that it is dome-shaped, symmetrical, surrounded by a smooth wall of inflamed skin, and capped with keratin scales and debris.

Verrucous hyperplasia is another type of epidermal squamous proliferation typified by broad and superficial downgrowths of the epidermis (Figure 8). Overlying hyper- and parakeratosis are present. Atypia and koilocytes are absent.

Enlarged regional lymph nodes. Lesion shows painful multiple rugae-like folds and deep clefts between them. We undertook a histopathological review of lesions excised from patients on BRAF inhibitor therapy, and found that 73% of lesions were squamoproliferative in nature.

They can be yellow to brown to black in colour or made up of several colours. Results: We found that 73% of lesions were squamoproliferative in nature, of which 14% met the criteria for a diagnosis of keratoacanthoma. 43% of the lesions showed verruca-like features and were designated as BRAF inhibitor associated verrucous keratosis (BAVK). Foci of acantholytic dyskeratosis were commonly observed in these lesions. The lesion continued to grow in size over time and was complicated by pain and occasional bleeding with trauma.

Of these, 33% met histologic criteria for a diagnosis of keratoacanthoma, whereas 43% showed features more in keeping with verruca vulgaris and were designated as BRAF inhibitor associated verrucous keratosis. It is a slow growing, diffuse, exophytic lesion usually covered by leukoplakic patches. Invasive lesions quickly invade bones. It can rapidly become fixed with underlying periosteum and cause gradual destruction of jaw bone. Enlarged regional lymph nodes. Lesion shows painful multiple rugae-like folds and deep clefts between them.

Epidermodysplasia verruciformis is an uncommon autosomal recessive disorder that predisposes patients to the development of squamous cell carcinoma (Figure 10). Actinic cheilitis is a condition These lesions appear to be truly severe intraepithelial neoplasia when they are associated with an underlying LS and could be considered as direct precursors of some invasive carcinomas.6, 7, 9 The lesions are often associated with squamous hyperplasia (SH).1, 2, 3, 7, 8, 13, 16 The lack of full-thickness change in differentiated PIN may lead the pathologist to underestimate its severity.

Verrucous carcinoma is characterized by diffuse and exophytic lesions covered by leukoplakic patches. It grows slowly over several years and forms a cauliflower-like lesion 3.0–5.0 cm in size with indolent pain within a few months after turning into a small wart-like mass.
