In 1948, ____ first described verrucous carcinoma, a low-grade tumor that generally is considered a clinicopathologic variant of squamous cell carcinoma. | Ackerman |
Early lesions appear as white, translucent patches on an erythematous base. They may develop in previous areas of leukoplakia, lichen planus, chronic lupus erythematosus, cheilitis, or candidiasis | Oral verrucous carcinoma |
The more fully developed lesions are white cauliflower-like papillomas with a pebbly surface that may extend and coalesce over large areas of the oral mucosa | Oral verrucous carcinoma |
Ulceration, fistulation, and invasion locally into soft tissues and bone (eg, mandible) may occur. Painful nonmalignant lymphadenopathy can be seen with concurrent infection. | Oral verrucous carcinoma |
