Speckled lentiginous nevus: within the spectrum of congenital melanocytic nevi.
BACKGROUND Currently, there is disagreement as to whether speckled lentiginous nevi (nevi spili) are congenital or acquired pigmented lesions. Part of this controversy is related to the natural history of these lesions that often present at birth as hyperpigmented patches and then take several years to reach their more readily recognized spotted form. Arguments in favor of speckled lentiginous ...
متن کاملCorrective but coordinates clauses not always but sometimes
The semantic contrast between COUNTEREXPECTATIONAL and CORRECTIVE but has long interested linguists (see Anscombre and Ducrot 1977 and much subsequent work). Recently, Vicente (2010) has proposed that the two types of but also differ in their syntax. While counterexpectational but coordinates constituents from a variety of different categories, corrective but always coordinates full clauses. Th...
متن کاملSegmental Speckled Lentiginous Nevus Exacerbated by Pregnancy in an Otherwise Healthy Female: A Case Report
Speckled lentiginous nevi (SLN), or nevus spili, are seen in 0.2% to 2.3% of the population, presenting as tan patches with overlying hyperpigmented macules or papules in a speckled arrangement. Segmental SLN represent a small subset of SLN, with the segmental type comprised of larger, unilateral lesions that may rarely give rise to melanomas and have been reported to proliferate in response to...
متن کاملGiant Maculo-Papular Speckled Lentiginous Nevus Associated with Isolated and Centrofacial Located Lentiginosus
Lentigines are usually flat, pigmented macules on the skin and mucosa. These lesions are characterized by mostly smaller than 0.5 cm, irregular borders and different shades of brown and black. They can be in the form of circumscribed or widespread lesions, and occur either as isolated lesion or as a part of some congenital syndromes. The speckled lentiginous nevus is also named as Nevus Spilus ...
متن کاملWhy trace and delay conditioning are sometimes (but not always) hippocampal dependent: a computational model.
A recurrent-network model provides a unified account of the hippocampal region in mediating the representation of temporal information in classical eyeblink conditioning. Much empirical research is consistent with a general conclusion that delay conditioning (in which the conditioned stimulus CS and unconditioned stimulus US overlap and co-terminate) is independent of the hippocampal system, wh...
