[Erythema anulare centrifugum with pustulation. Successful oral retinoid therapy]

Erythema anulare centrifugum with pustulation (EACP) is an unusual sterile pustulosis, which is believed to represent a rare type of pustular psoriasis. HLA-examination in this patient did not show, however, the typical pattern of vulgar of pustular psoriasis. No other signs of psoriasis were found either, except for the spongiform pustule. The EACP most likely corresponds to a special entity in the large group of psoriatic skin diseases. Oral retinoid therapy revealed full remission of the skin lesions.
