BACKGROUND: @entity11657 ( @entity11657 ) is a skin medium vessel neutrophilic @entity3468 with livedo, nodules, and @entity1066 . @entity1020 ( @entity1020 ) is a small @entity3468 with erythematous or pigmented macules and typical histologic features (a lymphocytic infiltrate, concentric fibrin ring, no disruption of the internal elastic lamina). OBJECTIVE: We sought to assess the frequency of clinical and histologic features of @entity1020 in @entity1 with @entity11657 . METHODS: This was a monocentric retrospective analysis of @entity1 given the diagnosis of @entity11657 with blinded assessment of skin biopsy specimens. RESULTS: All 35 @entity1 included had an infiltrated livedo, nodules, or both. Ulceration was rare. Erythematous or @entity66 were present in 54% of @entity1 . @entity3468 , a @entity8404 of neutrophils, concentric fibrin ring, and absence of internal lamina elastic disruption were present in 60%, 20%, 18%, and 23% of @entity1 , respectively. Median follow-up was 11  years. None of the @entity1 had systemic involvement, and 57% had a complete remission. The incidence of complete remission was not different between @entity1 having a predominant lymphocyte infiltrate or few neutrophils. LIMITATIONS: This was a retrospective, monocentric study without a control group of @entity1 with @entity1020 . CONCLUSIONS: Our data do not favor the classification of @entity11657 and @entity1020 as distinct entities.

Relationship between @entity11657 ( @entity11657 ) and XXXX ( @entity1020 ): Blinded histologic assessment of 35 @entity11657 cases.
