Malum perforans (also known as neurotrophic ulcer and trophic ulcer) is a long-lasting, usually painless ulcer that penetrates deep into or through the skin, usually on the sole of the foot (in which case it may be called malum perforans pedis). It is often a complication in diabetes mellitus and other conditions affecting the nerves. ==Cause== This condition results from denervation of areas exposed to day-to-day friction of bony prominences. The denervation may be result of any of the following diseases: * Spinal injuries * Leprosy * Peripheral nerve injury * Diabetic neuropathy * Tabes dorsalis * Transverse myelitis * Meningomyelocele 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「Malum perforans」の詳細全文を読む スポンサード リンク
