Between the group of pigmentary and purpury dermatitis, the eczematoid like purpura is better known for its clinical, histological and defined evolutive characteristics. We reviewed all existent biographies and presented two cases of this unusual afection, both with allergic backgrounds, inflammatory capillary lesions and purpura that began in the region of the malleolus and progressed towards the legs, thighs, pelvic girdle, until the chest. These lesions were essentially pruriginous. The histology did not demonstrate signs of allergic vasculitis. What drew our attention was the presence of red blood cells in the Malpighi stratum mucosa. Due to the scarcity of literature and few cases we were not able to clarify satisfactorily this epidermotrophism of the blood cells.
在色素沉着性皮炎和紫癜性皮炎组中,湿疹样紫癜因其临床、组织学和明确的演变特征而更为人所知。我们查阅了所有现存的病例记录,并展示了两例这种不寻常病症的病例,两例均有过敏背景、炎症性毛细血管病变以及始于内踝区域并向腿部、大腿、骨盆带直至胸部发展的紫癜。这些皮损本质上以瘙痒为主。组织学检查未显示过敏性血管炎的迹象。引起我们注意的是马尔皮基层黏膜中有红细胞存在。由于文献资料稀缺且病例较少,我们未能令人满意地阐明血细胞的这种表皮嗜性。
