Lethal cutaneous verrucous carcinoma

Verrucous carcinoma is a rare subtype of well-differentiated squamous cell carcinoma that may occur anywhere on the skin. It is slow growing, enlarging relentlessly and invading locally. Some cases were reported to occur on chronic scar tissue but demonstrated the same clinical course than in other locations. Herein, we report on a very unusual case of cutaneous verrucous carcinoma arisen from a long-standing (40 years old) burn scar and which involved the pleura five years after the initial surgical resection. To our best knowledge, this is the first case of pleural involvement by a verrucous carcinoma originating from the skin.
