Erythema papulatum centrifugum ( EPC ), also known as erythema papulosa semicircularis recidivans ( EPSR ), is distinct from eczema and other well‐described figurate erythemas characterised by annular erythematous lesions. We report 7 cases of EPC and propose new diagnostic criteria including the following: (i) EPC is characterised by single or multiple recurrent expanding annular or semi annular erythema with central regression, surrounded by tiny red papules; (ii) the lesions regularly relapse and resolve; (iii) the histopathologic feature shows superficial perivascular inflammation with or without mild inflammation around sweat glands in the mid dermis and (iv) patients lack other associated cutaneous or internal abnormalities.
