Pigmented purpuric dermatosis (also known as "progressive pigmentary dermatosis," "purpura pigmentosa chronica," "pigmentary purpuric eruptions," or "progressive pigmenting purpura") refers to one of the three major classes of skin conditions characterized by purpuric skin eruptions. Pigmented purpuric dermatosis are distinguished from other purpura by size (0.3–1 cm) and are most often seen in the lower extremities. Pigmentary purpuric eruptions may present with one of several clinical patterns. There may be overlapping characteristics among pigmented purpuric dermatosis and between their signs and those of other purpuric eruptions.〔 Examples of the pigmented purpuric dermatosis group include:〔 : * Schamberg's disease : * Majocchi's disease (Purpura annularis telangiectodes) : * Gougerot-Blum syndrome (Pigmented purpuric lichenoid dermatitis) : * Ducas and Kapetanakis pigmented purpura : * Lichen aureus Although vascular damage may be present, it is insufficient for these conditions to be considered forms of vasculitis. == See also == * Purpura * Skin lesion * List of cutaneous conditions 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pigmented purpuric dermatosis」の詳細全文を読む スポンサード リンク
