A Case of Nicolau Syndrome Due to Diclofenac Sodium / 대한피부과학회지

ABSTRACT

Nicolau syndrome is defined as local cutaneous and sometimes muscular necrosis observed at the injection site of intramuscular preparations. It is characterized by severe pain immediately after the injection and variable degrees of skin necrosis. The only treatment is conservative. A 46-year-old man presented with painful skin necrosis on his buttock after the injection of diclofenac sodium. Histopathologic examination showed necrosis of the epidermis and upper 2/3 of the dermis. The lesion was treated conservatively with topical antibiotic ointment. We report a rare case of Nicolau syndrome due to diclofenac sodium.
