Nutritional deficiencies result in many distinctive cutaneous manifestations. Vitamin C deficiency, or scurvy, produces follicular hyperkeratosis, perifollicular hemorrhages, gingival hypertrophy, and bleeding (1). We report here a case of malnutrition who suddenly developed extensive eccymoses on the lower extremities sharing morphological similarities with purpura fulminans. Although the patient did not have the characteristic dermatological features of scurvy, serum levels of vitamins C, K, B12, and E were decreased.
营养缺乏会导致许多独特的皮肤表现。维生素C缺乏症，即坏血病，会产生毛囊性角化过度、毛囊周围出血、牙龈肥大和出血（1）。我们在此报告一例营养不良患者，其下肢突然出现广泛瘀斑，形态与暴发性紫癜相似。尽管该患者没有坏血病的典型皮肤特征，但血清维生素C、K、B12和E水平均降低。
