Dermoscopy is a useful, noninvasive technique also used to assess sebaceous lesions in humans. Sebaceous hyperplasia, sebaceous adenoma and sebaceous epithelioma are common cutaneous lesions in dogs; however, their dermoscopic features have not been investigated.
HYPOTHESIS/OBJECTIVES: The objectives of this study are to describe the dermoscopic features of canine sebaceous lesions and to assess the interobserver agreement on dermoscopic parameters.
Thirty-four lesions excised from 17 client-owned dogs, histologically confirmed as sebaceous proliferations, were included in this study.
Sebaceous lesions were evaluated in vivo at ×10 magnification with a handheld dermoscope. Each dermoscopic image was assessed independently by two ECVD board-certified veterinary referral clinicians and an ECVD resident.
Thirty sebaceous hyperplasias, two sebaceous adenomas and two sebaceous epitheliomas were included. Dermoscopically, most lesions (91%) had single or multiple, well-defined, white-yellowish structures composed of grouped ovoid areas (clods). Irregular linear and, less commonly, arborising vessels were detected at the periphery of the yellow lobular-like structures in 93% of sebaceous hyperplasias and in 50% of neoplastic lesions. Erosions were seen in 6% of sebaceous hyperplasias and 50% of neoplastic lesions. Good interobserver agreement was found for white/yellowish clods (k = 0.75), yellow scales (k = 0.83), brown/grey dots (k = 0.80), erosions (k = 0.82) and red/brownish scales/crusts (k = 0.75). There was moderate agreement for fissures (k = 0.48) and vascular pattern (k = 0.51-0.53).
Dermoscopy represents a useful technique to assess sebaceous gland proliferations in dogs, as it is in humans.
皮肤镜检查是一种有用的非侵入性技术，也用于评估人类的皮脂腺病变。皮脂腺增生、皮脂腺腺瘤和皮脂腺上皮瘤是犬类常见的皮肤病变；然而，它们的皮肤镜特征尚未得到研究。
假设/目标：本研究的目的是描述犬皮脂腺病变的皮肤镜特征，并评估观察者之间在皮肤镜参数上的一致性。
本研究纳入了从17只客户拥有的犬身上切除的34个病变，经组织学证实为皮脂腺增生。
使用手持式皮肤镜在×10放大倍数下对皮脂腺病变进行体内评估。每张皮肤镜图像由两名欧洲兽医皮肤病学会（ECVD）认证的兽医转诊临床医生和一名ECVD住院医生独立评估。
包括30个皮脂腺增生、2个皮脂腺腺瘤和2个皮脂腺上皮瘤。在皮肤镜下，大多数病变（91%）具有单个或多个界限清楚的白色至淡黄色结构，由成群的卵圆形区域（凝块）组成。在93%的皮脂腺增生和50%的肿瘤性病变中，在黄色小叶样结构的周边检测到不规则线性血管，较少见树枝状血管。6%的皮脂腺增生和50%的肿瘤性病变可见糜烂。在白色/淡黄色凝块（k = 0.75）、黄色鳞屑（k = 0.83）、棕色/灰色斑点（k = 0.80）、糜烂（k = 0.82）和红色/棕色鳞屑/痂皮（k = 0.75）方面，观察者之间的一致性良好。在裂隙（k = 0.48）和血管形态（k = 0.51 - 0.53）方面，一致性中等。
与人类一样，皮肤镜检查是评估犬皮脂腺增生的一种有用技术。
