Pigment occurs almost exclusively in dermal studies as part of the response to topical application of a test article. Hence, pigment is typically accompanied by other lesions, such as inflammation (usually chronic or chronic active) or fibrosis. ## 英文原文 · Recommendation When warranted (based on the judgment of the pathologist), pigment should be documented and assigned a severity grade. If it is a minor component of inflammation, it need not be diagnosed separately but should be described in the narrative. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0492.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0496.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
