摘要

维生素 B12 和叶酸缺乏是巨幼红细胞性贫血的可逆原因。严格的素食主义者由于饮食中钴胺素含量低，有可能患巨幼红细胞性贫血。巨幼细胞性贫血患者的指关节色素沉着是由于皮肤黑色素合成过多所致。在此，我们介绍一例患有巨幼细胞性贫血并伴有指关节色素沉着的年轻素食男性患者，通过静脉注射维生素 b12 和叶酸后，患者的病情得到了成功控制。

Knuckle hyperpigmentation in a young male: A clinical sign of B12 deficiency not to be missed.

Vitamin B12 and folate deficiency are reversible causes of megaloblastic anemia. Strict vegetarians are at risk of megaloblastic anemia due to low cobalamin in their diet. Knuckle hyperpigmentation in patients with megaloblastic anemia is due to excess melanin synthesis in skin. Here we present a case of a young vegetarian male with megaloblastic anemia with knuckle hyperpigmentation managed successfully with intravenous followed by oral vitamin b12 and folate supplementation.
