Definition

Noun: * A skin condition, also known as keratoderma blennorrhagicum, characterized by the development of thick, scaly, and sometimes pustular lesions, primarily on the palms of the hands and the soles of the feet. It is a distinctive cutaneous manifestation strongly associated with reactive arthritis, particularly Reiter's syndrome.
