9. 抓痕：因搔抓或摩擦导致的线状或点状表皮或真皮浅层的剥脱性缺损。 10. 苔藓样变（lichenification)：因反复机械性刺激导致的皮肤局限性粗糙增厚，皮脊隆起，皮沟加深，常伴剧痒。 Pustule: A pustule is a circumscribed, raised lesion that contains a purulent exudate. 6.脓疱: 局限、隆起、内含脓液的腔隙性损害。 细菌性脓疱 非细菌性脓疱 Nodule： A nodule is a palpable, solid, round or ellipsoidal lesion. Depth of involvement and/or substantive palpability rather than diameter differentiate a nodule from a papule. 7. 结节：局限、实质、深在性皮损。 高出皮面 基本平齐皮面 Cyst: A cyst is a sac that contains liquid or semisolid material (fluid, cells, and cell products), on palpation, it is resilient. 8.囊肿: 含有液体和细胞成份的囊性损害。 继发性损害（secondary lesions） 指原发性皮损因自然演变而来，或因搔抓、治疗不当所致的继发性改变。 鳞屑、糜烂、浸渍、裂隙、萎缩、溃疡、结痂、抓痕、苔藓样变等 Erosion: A erosion is a moist, circumscribed, usually depressed lesion that results from loss of all or a portion of the viable epidermis. 1. 糜烂：表皮或粘膜上皮缺损导致的浅表湿润创面，愈后不留疤痕 Ulcer: An ulcer is a depressed lesion in which the epidermis and at least the upper dermis have been destroied. 2. 溃疡：皮肤或粘膜破溃后形成的深达真皮及以下的创面。 愈合后常形成瘢痕。 溃疡：皮肤缺损达到真皮或真皮以下 Scale, desquamation: Abnormal shedding or accumulation of stratum corneum in perceptible flakes is called scaling. 3. 鳞屑：已经脱落或即将脱落的角质层细胞 鳞屑：脱落的表皮细胞及其它成分 4. 浸渍（meceration)：因角质层含水过多所致的皮肤变软发白 5. 裂隙(fissure)：线状皮肤裂口，可深达真皮 6. 瘢痕：真皮或深部组织缺损后，由新生结缔组织修复而成。 增生性： 萎缩性： Atrophy: Atrophy refers to a diminution in the size of a cell, tissue, organ or part of the body. 7. 萎缩：因皮肤退行性变导致的表皮、真皮或皮下组织减少 Crust: Crusts are hardened deposits that result when serum, blood, or purulent exudate debris on the skin surface, and they are characteristic of pyogenic infections. 8. 痂：创面上多种成分混合干燥物 皮肤性病学示教 皮 疹SKIN LESIONS 表皮 真皮 皮下 皮疹的分类 原发性皮损（primary lesions） 由皮肤病理变化的直接结果 斑疹、斑块、丘疹、结节、风团、水疱、大疱、脓疱、囊肿等 继发性皮损（secondary lesions） 指原发性皮损因自然演变而来，或因搔抓、治疗不当所致的继发性改变。 鳞屑、糜烂、浸渍、裂隙、萎缩、溃疡、结痂、抓痕、苔藓样变等 原发性损害（primary lesions） 斑疹、斑块、丘疹、结节、风团、水疱、大疱、脓疱、囊肿等 Macule: A macule is a circumscribed, flat lesion that differs from surrounding skin because of its color. 1. 斑疹：皮肤黏膜的局限性颜色改变，与皮面平齐。 分类： (1)按大小分：1cm斑疹(
