Case Report

The road to diagnosis: presentation from erythema nodosum to vegetative pyoderma gangrenosum

診斷歷程:從結節性紅斑演化為增殖型壞疽性膿皮症

WYK Lam 林旭強 and KK Jong 莊國坤

Abstract

We report the rare occurrence of erythema nodosum and pyoderma gangrenosum at different times during the clinical course in a 30-year-old gentleman. He initially presented with biopsy-proven erythema nodosum over both shins. He subsequently developed multiple violaceous and vegetative nodules over the upper and lower limbs. Three serial skin biopsies were performed thereafter. A diagnosis of vegetative pyoderma gangrenosum was made based on the clinical findings and histopathological features. He showed good treatment response to oral steroid.

我們報告了一名三十歲男仕的罕見臨床病況,他在不同時期出現了結節性紅斑及壞疽性膿皮症。他最初在雙腿脛部出現活檢證實的結節性紅斑,四肢繼而長出多個紫蘿蘭色的增殖性結節。其臨床表現結合其後三個切皮檢查的病理組織學特徵,被確診為增殖型壞疽性膿皮症;施以口服類固醇治療後,病情得到明顯改善。
