ia,whichusuallypresentssymptomswithinminutestohoursandsubsideswithindaystoweeks.Acuteurticariaisusuallyassociatedwithspecifictriggeringfactors,suchasfoodallergies,drugallergies,orinfections.慢性荨麻疹：当荨麻疹症状持续超过6周时，即被定义为慢性荨麻疹。这种类型的荨麻疹往往没有明确的病因，也可能与免疫系统疾病、内在疾病或持续的环境因素有关。Chronicurticaria:Whenthesymptomsofurticariapersistformorethan6weeks,itisdefinedaschronicurticaria.Thistypeofurticariaoftenhasnoclearcauseandmayalsoberelatedtoimmunesystemdiseases,underlyingdiseases,orpersistentenvironmentalfactors.物理性荨麻疹：这种荨麻疹是由物理刺激引起的，如寒冷、压力、热、光或水。常见的物理性荨麻疹类型包括寒冷性荨麻疹、压力性荨麻疹、热性荨麻疹等。Physicalurticaria:Thistypeofurticariaiscausedbyphysicalstimulisuchascold,pressure,heat,light,orwater.Commontypesofphysicalurticariaincludecoldurticaria,stressurticaria,andhoturticaria.胆碱能性荨麻疹：这种类型的荨麻疹通常在身体活动增加、受热、情绪激动或摄入热食后触发，因为这些情况会导致体内胆碱的释放。Cholinergicurticaria:Thistypeofurticariaisusuallytriggeredbyincreasedphysicalactivity,heating,emotionalarousal,oringestionofhotfood,astheseconditionscanleadtothereleaseofcholineinthebody.水源性荨麻疹：当皮肤与水接触后出现荨麻疹症状时，即被定义为水源性荨麻疹。这种类型的荨麻疹可能与水的温度、水质或水中的某些物质有关。Watersourceurticaria:Whensymptomsofurticariaappearafterskincontactwithwater,itisdefinedaswatersourceurticaria.Thistypeofurticariamayberelatedtothetemperature,waterquality,orcertainsubstancesinthewater.接触性荨麻疹：这种类型的荨麻疹是由皮肤接触某些物质（如化学物质、植物、动物等）引起的。Contacturticaria:Thistypeofurticariaiscausedbyskincontactwithcertainsubstances(suchaschemicals,plants,animals,etc.).每种类型的荨麻疹都有其特定的临床表现和治疗策略，因此准确的分类对于制定合适的治疗方案至关重要。在荨麻疹的诊断过程中，医生应根据患者的病史、体格检查和必要的实验室检查来确定荨麻疹的类型和病因。Eachtypeofurticariahasitsspecificclinicalmanifestationsandtreatmentstrategies,soaccurateclassificationiscrucialfordevelopingappropriatetreatmentplans.Inthediagnosisofurticaria,doctorsshoulddeterminethetypeandcauseofurticariabasedonthepatient'smedicalhistory,physicalexamination,andnecessarylaboratorytests.四、诊断Diagnosis荨麻疹的诊断主要依赖于详细的病史、体格检查以及必要的实验室检查。荨麻疹的典型临床表现是突然出现、大小不形状各异的风团，这些风团往往瘙痒剧烈，且可能在数分钟至数小时内消退，不留痕迹，但新的风团可能此起彼伏，不断发生。Thediagnosisofurticariamainlyreliesondetailedmedicalhistory,physicalexamination,andnecessarylaboratorytests.Thetypicalclinicalmanifestationofurticariaissuddenappearanceofwindmassesofvarioussizesandshapes.Thesewindmassesoftenhavesevereitchingandmaydisappearwithoutleavingatracewithinminutestohours.However,newwindmassesmayemergeoneafteranotherandcontinuetooccur.病史采集：医生需要详细询问患者荨麻疹发作的时间、频率、持续时间、伴随症状（如发热、关节痛等）以及可能的诱发因素（如食物、药物、感染等）。同时，还应了解患者的既往病史、家族病史以及个人生活习惯等，以排除其他可能引起荨麻疹的疾病。Medicalhistorycollection:Doctorsneedtoaskpatientsindetailaboutthetime,frequency,duration,accompanyingsymptoms(suchasfever,jointpain,etc.)ofurticariaattacks,aswellaspossibletriggeringfactors(suchasfood,medication,infection,etc.).Atthesametime,itisalsonecessarytounderstandthepatient'spastmedicalhistory,familyhistory,andpersonalhabitstoexcludeotherdiseasesthatmaycauseurticaria.体格检查：医生应对患者的皮肤进行仔细检查，观察风团的大小、形状、颜色以及分布情况。还应检查其他部位，如口腔、咽喉、眼结膜等，以评估荨麻疹的严重程度和可能的并发症。Physicalexamination:Doctorsshouldcarefullyexaminethepatient'sskin,observingthesize,shape,color,anddistributionofwindmasses.Otherareassuchasthemouth,throat,andconjunctivashouldalsobeexaminedtoassesstheseverityofurticariaandpotentialcomplications.实验室检查：在某些情况下，可能需要进行实验室检查以辅助诊断。例如，血常规检查可以了解患者是否有感染或过敏反应；过敏原检测可以帮助识别引起荨麻疹的特定过敏原；免疫球蛋白E（IgE）检测可以评估患者的过敏状态；皮肤活检则可用于排除其他皮肤疾病。Laboratoryexamination:Insomecases,laboratoryexaminationmaybenecessarytoassistindiagnosis.Forexample,abloodroutineexaminationcandeterminewhetherapatienthasaninfectionorallergicreaction;Allergentestingcanhelpidentifyspecificallergensthatcauseurticaria;ThedetectionofimmunoglobulinE(IgE)canevaluatethepatient'sallergicstatus;Skinbiopsycanbeusedtoexcludeotherskindiseases.鉴别诊断：荨麻疹的诊断需要与其他可能引起皮肤风团和瘙痒的疾病进行鉴别，如药疹、丘疹性荨麻疹、接触性皮炎等。还应排除一些严重疾病，如系统性红斑狼疮、皮肌炎等，这些疾病也可能出现类似荨麻疹的临床表现。Differentialdiagnosis:Thediagnosisofurticarianeedstobedistinguishedfromotherdiseasesthatmaycauseskinrashanditching,suchasdrugrash,papularurticaria,contactdermatitis,etc.Someseriousdiseases,suchassystemiclupuserythematosusanddermatomyositis,shouldalsobeexcluded,asthesediseasesmayalsopresentwithclinicalmanifestationssimilartourticaria.荨麻疹的诊断需要结合患者的病史、体格检查和实验室检查进行综合判断。正确的诊断对于制定有效的治疗方案和预防荨麻疹的复发具有重要意义。Thediagnosisofurticariarequiresacomprehensiveassessmentbasedonthepatient'smedicalhistory,physicalexamination,andlaboratorytests.Thecorrectdiagnosisisofgreatsignificanceforformulatingeffectivetreatmentplansandpreventingtherecurrenceofurticaria.五、总结与建议Summaryandsuggestions荨麻疹作为一种常见的皮肤病，其定义、分类和诊断对于临床医生来说至关重要。本文旨在提供一份详尽的荨麻疹指南，帮助医生更好地理解和处理这一疾病。Urticaria,asacommonskindisease,itsdefinition,classification,anddiagnosisarecrucialforclinicaldoctors.Thisarticleaimstoprovideadetailedguideforurticariatohelpdoctorsbetterunderstandandmanagethisdisease.在定义方面，荨麻疹是一种表现为皮肤红斑、水肿和瘙痒的过敏反应。这种反应可以由多种内外因素触发，如食物、药物、感染、物理刺激等。根据病程的长短，荨麻疹可分为急性荨麻疹和慢性荨麻疹。急性荨麻疹通常在数小时至数天内消退，而慢性荨麻疹则持续数周至数月，甚至数年。Intermsofdefinition,urticariaisanallergicreactioncharacterizedbyskinredness,edema,anditching.Thisreactioncanbetriggeredbyvariousinternalandexternalfactors,suchasfood,medication,infection,physicalstimulation,etc.Accordingtothedu
