Paraneoplastic acrokeratosis, also known as Bazex syndrome, is a skin sign associated with cancer.[2] It is characterized by psoriasiform changes of hands, feet, ears, and nose, with involvement of the nails and periungual tissues being characteristic and indistinguishable from psoriatic nails. The condition is associated with carcinomas of the upper aerodigestive tract.[3]: 665 

It is rare, and seen most frequently in white males.[2] A case was first reported by Henri Gougerot and C. Grupper in 1922.[4][5] Andre Bazex described it as a paraneoplastic syndrome in 1965.[4][6]
