ANNULAR VASCULITIS ASSOCIATED WITH PREGNANCY

A 29-year-old woman presented in the 31st week of pregnancy with an un usual bilateral, erythematous eruption on the posterior calves, which clinically resembled erythema annulare centrifugum. A biopsy showed fe atures of a mild leucocytoclastic vasculitis. Within 2 days of deliver y the rash had almost resolved, suggesting that its activity was relat ed to the pregnancy. The diagnosis is consistent with 'annular vasculi tis', which we suggest represents a distinct variant of leucocytoclast ic vasculitis, and a distinct clinicopathological entity. We are not a ware of any previous reports of an association between annular vasculi tis and pregnancy.
