INTRODUCTION Oral verrucous carcinoma (OVC) is a rare malignancy of the oral cavity that was first described by Ackerman. This tumor is a well-differentiated low-grade, slow growing cancer that is locally invasive without metastasis. Ameloblastoma is one of the most common odontogenic tumors, which originates from the odontogenic epithelium. Verrucous carcinoma along with central ambloblastoma ...

β-Catenin acts as a structural protein at cell-cell adherens junctions and as a transcription activator mediating Wnt signal transduction. Altered β-catenin expression has been associated with loss of cell differentiation and acquisition of an invasive phenotype. In the present study, β-catenin expression was compared immunohistochemically between oral squamous cell carcinoma (30 cases) and ver...

We report a rare case of verrucous carcinoma occurring in the nasal cavity. A 53-year-old man reporting left-sided nasal obstruction and awareness of a left intranasal lesion--a whitish polypoid lesion--was found in CT to have an expansive lesion of the left nasal cavity and maxillary sinus. The tumor was completely removed by Denker's operation. Verrucous carcinoma is a rare variant of squamou...

Verrucous carcinoma is a peculiar type of squamous cell carcinoma character­ized by a clinicopathological behavior.This neoplasm is grossly cauliflower, warty, or parachute in shape, slowly growing and pushing the adjucent tissue without a definite invasion. Rarely causing metastasis. This tumor is radio­resistant and the choice treatment is surgery. Histological features resemble the papilloma...

Verruco-papillary lesions (VPLs) of the oral cavity described in the literature involve a spectrum of conditions including squamous papilloma, verruca vulgaris, focal epithelial hyperplasia, condyloma, proliferative verrucous leukoplakia and verrucous carcinoma. A majority of the VPLs are slow growing, benign in nature and have a viral aetiology. Virus associated benign mucosal outgrowths are ...

Verrucous carcinoma (also known as Ackerman tumor) is an uncommon exophytic low-grade well-differentiated variant of squamous cell carcinoma. This neoplasm typically involves the oral cavity, larynx, genitalia, skin, and esophagus. It is well known for its locally aggressiveness and for its clinically slow-growing behaviour with minimal metastatic potential. Verrucous carcinoma of oral cavity i...

Abstract Introduction Verrucous squamous cell carcinoma is a rare tumour of the oesophagus with a few reported cases in the literature. While it is an uncommon malignancy, the natural history is substantially more favourable compared to adenocarcinoma and squamous cell carcinoma. A pre-operative tumour biopsy with unyielding results is not uncommon for this type of tumour. In the following repo...

Verrucous carcinoma (VC) is an exophytic, low-grade, well-differentiated variant of squamous cell carcinoma. It is described as a lesion appearing in the sixth or seventh decade of life that has minimal aggressive potential and, in long-standing cases, has been shown to transform into squamous cell carcinoma. Oral submucous fibrosis (OSMF) is a potentially malignant disorder, and about one-thir...

Leprosy (Hansen's disease) is a chronic granulomatous disease caused by Mycobacterium leprae (Hansen's bacillus). Oral manifestations occur in 20-60% of cases, usually in lepromatous leprosy, and are well documented. They may involve both the oral hard and soft tissues. Incidence of verrucous carcinoma/Ackerman's tumour developing in anogenital region and plantar surfaces of feet in lepromatous...
