Context.--Atypical genital nevus is rare and the only poorly documented melanocytic lesion in the spectrum of nevi of special sites. It is characterized by unique and reproducible histologic features, which may appear alarming and may raise significant concern for a diagnosis of melanoma. Objectives...
Spindle cell nevus (juvenile “melanoma,” Spitz nevus) is a special form of compound nevus that occurs predominantly in children, often as a solitary lesion on the face. 1. Histologically, it superficially resembles a malignant melanoma, but biologically it is benign. 2. It may contain spindle...
With evidence of mitotic activity in a significant fraction of naevi,30,31the view that naevi are static collections of senescent melanocytes is not supported; moreover, the clinical observation of naevi regenerating after incomplete excision, another frequent source of diagnostic dilemmas, supports the...
For documentation purposes we registered an overview, and the following standardized dermoscopic images of every lesion: representative architectural pattern, border of the lesion, and regions of "special interest." In all instances the examination with digital dermoscopy was well tolerated by the patient...
They are currently regarded as nevi of special sites, in that despite histologically worrisome features, their clinical behavior is reportedly benign. However, only few studies with limited follow-up data are available. To better characterize the clinical presentation and behavior of these lesions ...
In a previous article, we have published the first part of a work about acquire melanocytic nevi, studying mainly the Miescher's nevus. In this second part we have studied acquire melanocytic nevi (except blue nevus) on the trunk and limbs (except palms, soles and genitalia), focused on th...
The mean fluence of treatment was 2.5J/cm(2) (range 2.0-5.0J/cm(2) ). Five patients complained of delayed eyelid response. Post-therapy hyperpigmentation was observed in one patient.Low fluence 1064nm Q-switched Nd:YAG laser is an effective modality for the treatment of nevus of Ota with...

BSL Clinic’s Pigmentation Removal Laser aims to destroy unwanted pigments, removing the leading causes of freckles and dark spots. This particular type of laser penetrates the skin breaking the pigments into small granules. The white blood cells within an individual’s body will dispose of these ...
In this chapter, the issue of vulvar nevus will be clearly defined with emphasis on the varying degree of cytologic atypia that occur on this special site as well as other features such as mitotic activity, maturation, and unusual growth feature that accompanied time of altering hormone during ...
