Two patients showed symmetrical sclerodermoid (morphea-like) skin lesions at sites of intramuscular phytonadione (vitamin K1) injections. The lesions appeared one and two years after the injections. A dense sclerosis involving the reticular dermis and subcutaneous fat was observed on histologic examination of biopsy specimens. Local adverse reactions to phytonadione are reviewed. Possible causative mechanisms for phytonadione-induced pseudoscleroderma are discussed.
