Abstract Background: Childhood is a dynamic period regarding nevogenesis. Dermoscopy is a noninvasive technique, recommended for the evaluation of pigmented cutaneous lesions. Objectives: The purpose of this study was to describe the structures and dermoscopic patterns of melanocytic nevi observed in c...
Abstract The present study aimed to determine the prevalence of Kamino bodies in Reed nevus, since most studies to date show conflicting data on this issue. This was a retrospective observational study, in which the histopathology of 19 Reed nevus lesions were reviewed. The slides were stained by hematox...
ABSTRACT Purpose: To compare measurements of lesions clinically diagnosed as choroidal nevi using spectral domain optical coherence tomography (SD-OCT) and 10- and 20-MHz ultrasound (US). Methods: This prospective study, which was conducted between May 2011 and December 2011, evaluated eyes diagnosed w...
Abstract: Background: Large congenital melanocytic nevus (LCMN) is considered a risk factor for melanoma, although the magnitude of this risk is controversial. Objective: To evaluate the risk of melanoma development in patients with LCMN seen at a dermatology referral center in Brazil during a twelve-y...
Abstract: Proliferative nodules can occasionally arise on congenital and acquired melanocytic nevi. At first sight their clinical and pathologic features cause alert to both dermatologist and dermatopathologist.

Abstract: Although giant congenital melanocytic nevus is a rare lesion, it causes significant deformity and carries a risk of malignant degeneration. Different surgical techniques for the lesion removal are described, including serial resection, resection with skin grafting, and resection and coverage wi...
Abstract: Nevus spilus is a melanocytic cutaneous lesion consisting of a light brown background macule with numerous superimposed darker maculopapular speckles. Melanoma arising from a nevus spilus is rare, with less than 40 cases reported to date. The absolute risk for malignant transformation is not we...
Abstract Divided nevus, also known as kissing nevus, is a rare variant of congenital melanocytic nevi in which there are two adjacent nevi in areas of the body that undergo embryonic cleavage. The original description of this type of lesion was on the eyelid. The location on the penis is even rarer, with...
Abstract Phacomatosis pigmentovascularis is a rare syndrome, defined as the simultaneous presence of vascular nevus and melanocytic nevus in the same patient.
