    Studysummary In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions. Our plain-language summary of this paper — not a Tressless recommendation.
    Reflectance confocal microscopy (RCM) was utilized to assist in the diagnosis of periorificial dermatitis (PD), an inflammatory facial skin disorder. The RCM images revealed slight edema in the spinous layer, numerous dendritic cells, keratotic plugging and dilation of hair follicles, as well as dilation and congestion of blood vessels in the superficial dermis. Additionally, there was an observed increase in vascular density, accelerated blood flow, and a higher number of infiltrated inflammatory cells. These findings helped to differentiate PD from other similar dermatological conditions such as acne, seborrheic dermatitis, granulomatous rosacea, sarcoidosis, and childhood granulomatous periorificial dermatitis.
