LEisincreasinglybeingrecognizedasamorecommonautoimmunedisorderthan was previously thought,and thecutaneous manifestations ofLEareamong themost commonclinicalfeatures ofLEatits onset and throughoutits course.Themost com- monly recognized environmental risk factor for LE,ultraviolet light exposure from sunlightandartificial sources,necessarily transduces its disease-exacerbatingeffect through the skin.Cutaneous LEcanbeasignificant contributor topsychosocialand occupationaldisability.Inaddition,the universally recognized symbols of LE– the butterfly and the wolf– relatetodifferent cutaneous manifestations ofLE. Yet,the skinhas been theleast well-studiedorgan system that is affectedbyLE. This has resultedfrom the relative“invisibility”ofthe skinand skindisease tonon- dermatologists whodeal withpatients withLE.After all,“it’s only arash.”Perhaps this wouldbeless ofaproblemifnondermatologist physicians werebetter trainedin the principles andpracticeofrecognizingandmanaging skindiseases during their for- malmedicaleducation.Also,contributing to this is thefactthat expertmanagement ofLEand rheumatic skindiseaseingeneralareatriskofbeinglost from thederma- tologist’srepertoirein someparts ofthe world,including theUnitedStates. However,toarelatively small subset ofacademicdermatologists who subspecial- izein thecutaneous manifestations ofLE,theproteanchanges thatcanoccur in the skinofpatients withLEcanbebothfascinatinganddaunting.Howasingledisease process plays out somany different themes ina singleorgan systemis truly amazing! This matrix becomes evenmorecomplex whenoneconsiders the relationships that exist between the various morphologic varieties of skinchangeinpatients withLE and the various systemicmanifestations ofLE.Muchis yet tobelearnedin this area! Weareindeedfortunatethat Drs.Kuhn,Lehmann,andRuzickahaveassembleda highly experiencedandexpertgroupof individuals toaddress the various subjects presentedin this monograph.Frommyperspective,this has beenawonderful,soup- to-nuts tour ofour currentunderstandingofallmajor aspects ofLE skindisease.It is my hope that this effort willcatalyzefurther thought andprogress in this area. IowaCity,Iowa,USA RichardD.Sontheimer June 2004 Preface Lupus erythematosus (LE)is achronicinflammatory autoimmunediseasecharacter- izedby a wide spectrumofmanifestations anda variableevolution.The skinis one ofthemost frequent sites ofinvolvement,and thus it has longbeencentral tothecon- ceptual framework that physicians have used to deal with this disease.During the past few decades,themechanisms ofcutaneous LEhavebeen under activeinvestiga- tion,and many clinicians and scientists around the world have spent considerable time studying thecutaneous manifestations ofthis disease.This researchhas led to theidentificationofsubsets ofLEdefinedby constellations ofclinicalandphotobio- logical features,histologic and immunopathologic changes,and laboratory abnor- malities.Besides the classic forms such as subacute cutaneous LE and discoid LE, there are uncommon variants that often lead to diagnostic difficulties. Therefore, therehas longbeenaneedforabookonthecutaneous manifestations ofLE thatpro- vides not only acomprehensivedescriptionofthegreat variety ofcutaneous abnor- malities but alsoa synthesis ofour knowledgeofthe relationshipbetweencutaneous and systemicchanges.Furthermore,thecutaneous manifestations ofthis diseaseare a reflection of very specific and also nonspecific immunopathologic events along withinflammatory responses,andmajor progress has beenmadein recentyears in our knowledgeofthe skinas animmunologicorgan.Manyadvances havealsobeen madein understanding theinductionofskinlesions ofLEbyultraviolet light com- bined withalterations in selectins andadhesionmolecules contributing to theaccu- mulationofinflammatory cells in this disease.Animalmodels ofLEhavefurther pro- vided insight into the contributing roles of various T-cell subsets.In addition,the management ofcutaneous manifestations ofLEis challenging,andalthoughconven- tional topical and systemic therapy exists new treatment options have been intro- ducedfor patients with resistantdisease. Cutaneous Lupus Erythematosusis writtenby leadingclinicians and scientists ina multidisciplinary effort and includes chapters on the clinical aspects, pathologic characteristics,andmanagement ofthis disease.Thecombinationofthelatest clini- cal and scientific data supplemented with colour reproductions of the clinical and pathologicchanges ofthe skinprovides acomprehensive summary ofinformationon cutaneous LE. This book acquaints dermatologists, rheumatologists, and general physicians with the skinmanifestations of LE,and wefurther hope that Cutaneous LupusErythematosuswillbea valuable resourcefor allclinicians whodiagnose,treat, andmanagepatients with this disease.Theeditors wouldlike to thankallauthors for their significant contribution to accomplish this book. In addition, the editors dedicatethis book to thememoryoftheir mentor,colleague,andfriendDr.Günther VIII Preface Goerz, Professor of Dermatology, University of Düsseldorf, Germany, who taught them that LEis exciting,complex,and worth spendingalifetime studying.
