Erythema multiforme‐like reaction associated with radiotherapy

SUMMARYGeneralized cutaneous reactions in association with radiotherapy have in the past been grouped into erythema multiforme (EM) and erythema multiforme‐like reactions, the latter being reactions that do not strictly fit the accepted clinical and/or histological criteria for EM, yet have similar findings or presentations.Though usually benign and self‐limiting, the progression to Stevens‐Johnson syndrome, a potentially fatal form of erythema multiforme, has been reported. Presented here is a case study of a less severe radiation‐induced erythema‐like reaction.
