Verrucous_carcinoma

Verrucous carcinoma is a variant of squamous cell carcinoma. This form of cancer is often seen in those who chew tobacco or use snuff, so much so that it is sometimes referred to as "Snuff dipper\'s cancer." It is also known as an Ackerman tumor.

Most patients with verrucous carcinoma have a good prognosis. Local recurrence is not uncommon, but metastasis to distant parts of the body is rare. Patients with oral verrucous carcinoma may be at greater risk of a second oral squamous cell carcinoma, for which the prognosis is worse.
