Case of acrodermatitis continua accompanied by psoriatic arthritis

Acrodermatitis continua of Hallopeau (ACH) is a rare chronic pustular eruption that predominantly involves the fingertips. The characterization of this disease has been confused. Some have considered it as a separate entity while others as a variant of pustular psoriasis. The presented patient simultaneously had ACH and joint lesions which were diagnosed as psoriatic arthritis. We believe that because ACH may be accompanied by psoriatic arthritis, as in this case, it could be evidence that it is a variant of psoriasis.
