Nicolau syndrome or embolia cutis medicamentosa is a very rare, but well recognized complication of intramuscular injections which clinically presents with extensive necrosis of the injected skin area. Intra-arterial or para-arterial injection after unintentional perforation of certain vessels could be the possible mechanisms. We describe 2 cases of Nicolau syndrome resulting from intramuscular injection of Diclofenac. Since irreversible tissue damage may occur within a short duration and, as the there is no definitive treatment for this condition, precautionary measures are emphasized.

Erythema multiforme (EM) is usually an acute and self-limited inflammatory reaction of the skin and mucous membranes. Attacks may be sporadic or recurrent, and generally last for 1 to 3 weeks. ⋯ This continuous and uninterrupted occurrence of typical and atypical lesions is known as persistent EM. We present a case responsive to dapsone.
