A rare type and an unusual location of squamous cell carcinoma with bone invasion

Verrucous carcinoma (VC) is an uncommon, distinct type of well-differentiated squamous cell carcinoma in which metastasis is rare. It is locally agressive and often affects deep structures such as tendons, muscles and bone in which invasion remain rare. Verrucous carcinoma is commonly misdiagnosed as a wart or chronic infection for months or years. We report a case of a 85-year-old woman with a verrucous carcinoma developing in an intertriginous area of the foot with bone invasion.
