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. It grows rapidly, reaching a large size within days or weeks, and if untreated for months will almost always starve itself of nourishment, necrose

Introduction Neoplastic lesions involving the nasal cavity and paranasal sinuses are rare and have a diverse patho-logic diagnosis. Approximately 3% of all head and neck neoplastic lesions are sinonasal carcinomas. 1 The most common type of sinonasal carcinoma is squamous cell carcinoma.2 Verrucous carcinoma (VC) is a low-grade Papillary and verrucous lesions of the oral mucosa Gareth J Thomas a William Barrett Abstract a variety of verrucous and papillary lesions affect the oral mucosa. Those which are benign and reactive, for example squamous papilloma or ver-ruciform xanthoma, usually present little diagnostic difficulty. 2014-09-24 2020-07-23 2012-08-21 The etiologic agent remains elusive, but based on our findings, we conclude that verruciform xanthoma is most likely not a human papillomavirus-associated squamoproliferative lesion and that the foam cells, a histologic hallmark of the lesion, are most likely derived from dermal dendritic cells. We undertook a histopathological review of lesions excised from patients on BRAF inhibitor therapy, and found that 73% of lesions were squamoproliferative in nature. 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.

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. PAS “Atypical Squamoproliferative lesion”. Resection of tongue: SCC, moderately differentiated.

Because the size of the lesion favored an underlying verrucous carcinoma, our patient underwent minimally invasive esophagectomy with gastric pull-up and cervical anastomosis. 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).
