Vitamin K1 dermatitis is a cutaneous adverse reaction to vitamin K1, and this malady presents as an erythematous eczematoid patch or pseudoscleroderma. At first, liver disease was thought to be related to vitamin K1 dermatitis. However, it is no longer considered as being related to liver disease due to the increasing case reports of patients with vitamin K1 dermatitis and who are without liver disease. Type IV hypersensitivity reaction was suspected to be the cause of this reaction. This disease can be easily ignored because of its low incidence. We hereby report on a case of vitamin K1 dermatitis that was confirmed by a skin test.
