PSORIATIC-ARTHRITIS OR OVERLAP SYNDROME

In this work we describe a case of papillophlebitis type II according to Hayreh in a young woman affected by psoriatic arthritis. On the bas is of an analysis of the patient's HLA system - B7, DR7 (characteristi cs of psoriatic arthritis) and B51 (present in 81% of patients affecte d by Behcet's syndrome) - we hypothesize that this may be a case of an 'overlap syndrome'. In rheumatology, this term usually refers to the presence in a single patient of characteristic features of two or more diseases. In fact, papillophlebitis is a complication which has never been described in psoriatic arthritis, while, in Behcet's syndrome, r etinal vasculitis is well known.
