Erythema Nodosum as Azathioprine Hypersensitivity Reaction in a Patient with Bullous Pemphigoid. Indian J Dermatol. 2013 ; 58(5):4060019-5154http://hdl.handle.net/10668/1312JOURNAL ARTICLE;A 65-year-old woman with bullous pemphigoid presented with fever and several red-purple nodular subcutaneous lesions on both lower legs 1 week after starting treatment with azathioprine (AZA). Biopsy of a skin nodule was compatible with erythema nodosum (EN) and hypersensitivity reaction to AZA was suspected. AZA was subsequently discontinued, observing complete remission of fever and EN within 2 weeks. This case highlights the importance of recognizing EN as a possible manifestation of hypersensitivity reaction to AZA.esAzathioprinebullous pemphigoiderythema nodosumhypersensitivity syndromeAzatioprinaEritema NudosoPenfigoide AmpollosoHipersensibilidad a las DrogasFemeninoMedical Subject Headings::Chemicals and Drugs::Organic Chemicals::Sulfur Compounds::Thionucleosides::AzathioprineMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin Diseases::Erythema::Erythema NodosumMedical Subject Headings::Diseases::Skin and Connective Tissue Diseases::Skin Diseases::Skin Diseases, Vesiculobullous::Pemphigoid, BullousMedical Subject Headings::Diseases::Immune System Diseases::Hypersensitivity::Drug HypersensitivityMedical Subject Headings::Check Tags::Femaleresearch article24082202open access10.4103/0019-5154.1173321998-3611
