“…The main dermoscopic features observed in 91% of the lesions were white/yellowish clods and irregular linear vessels at the periphery of the lesions. These features are similar to those reported in humans 5,6 and correspond to grouped dermal sebaceous lobules. In humans, the dermoscopic finding of yellow lobular-like structures has been described in sebaceous hyperplasia, sebaceous adenoma and nevus sebaceous of Jadassohn.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…This image is similar to those observed in xanthogranulomas, with yellowish cloud-like structures over an orange-yellow background, being the "elouds" identified as the xanthogranulomatous dermal infiltrate (13) and resembling the yellow nodules present in sebaceous hyperpiasias (14). also named "cumulus sign" (Î5).…”

“…On dermoscopy each lesion showed a characteristic orange-yellow background colouration, with ‘clouds’ of paler yellow deposits consistent with a xanthogranulomatous dermal infiltrate. The ‘clouds’ of paler yellow deposits are similar to those seen in sebaceous hyperplasia [7]. To our knowledge this dermoscopic feature has not been described in xanthogranulomatous lesions.…”
