Abstract: Abstract:Reed nevus or pigmented spindle-cell nevus may mimic cutaneous melanoma; however, its dermoscopic and histopathological characteristics are different. This case report describes three patients with distinct clinical, dermoscopic and histopathological presentations, which were correlated to enable a differential diagnosis to be made between melanoma and Spitz nevus Keywords: Dermoscopy; Melanoma; Nevus, spindle cell Resumo: O nevo de Reed ou nevo de células fusiformes pigmentado pode ser um simulador d… Show more

“…This is a pattern with prominent central pigmentation, diffuse, bluish-gray or black, also called black lamella, corresponding to the region of greatest parakeratosis, and streaks distributed around the lesion that correlate to areas of cell nest compression observed in histopathology. 14 19.4% of the cases have regular and prominent pigment network, and 8.3%, have a bluish-black pigmentation without streaks in the periphery (Figures 3 and 4).…”

“…However, there is still no consensus in the literature. 8 In 1975, Reed et al 7,[11][12][13][14][15] described a deeply pigmented melanocytic lesion, also benign, found especially in the lower extremities of young adults. Some authors consider it as a single nosological entity, but others refer to it as a pigmented variant of the classic Spitz nevus, with its own clinical and histological features.…”

“…Some authors consider it as a single nosological entity, but others refer to it as a pigmented variant of the classic Spitz nevus, with its own clinical and histological features. 6,7,11,12,13,14,16,17 Whether Spitz and Reed nevi are distinct lesions is still debatable. 6 For this reason, some authors try to differentiate them in histological types, but there are controversies, as the combination of their microscopic characteristics is very common.…”

“…4 Reed nevus is characterized by a dark brown or black papule or plaque, often affecting the lower limbs of young women around the third decade of life; however, it can occur in children and young adults of both sexes ( Figure 2). 11,14,16,21 It is usually smaller than Spitz nevus. 16 It can grow fast.…”

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.
