Giant congenital nevi are usually larger than 6 cm on the trunk, 9 cm on the scalp in an infant, or greater than 20 cm in its largest diameter in an adult. A congenital nevus (mole) is a proliferation of benign melanocytes, also known as a birthmark, that develops before or shortly after birth. This crosssectional study aimed to correlate CN dermoscopy and RCM patterns and identify the prevalent patterns according to age groups. The findings varied with age and the anatomic location of the nevus, with the globular pattern found more often in younger children and the reticular pattern found in patients aged 12 years or older [ 14 ]. .

Dermoscopy may also assist in evaluating, screening, and monitoring of fl at large CMN. . . A pigment network has a grid-like pattern consisting of interconnecting pigmented lines surrounding hypopigmented holes. In this study, we set out to determine the clinical and dermoscopic properties of CMN. A brown or black melanocytic naevus contains the pigment melanin, so may also . Kittler Congenital nevus superficial. Malignant melanoma Incidence is increasing (approaches 3% lifetime risk) Maintain a higher level of suspicion. Abstract Abstract: Melanonychia striata in childhood is primarily due to congenital nevi, but melanoma should be excluded. Peer Reviewed. Introduction. ND is an uncommon congenital pigmentary disorder characterized by the circumscribed area of depigmentation. Evaluation of the congenital melanocytic naevus by dermoscopy will reveal the pattern of pigmentation and its symmetry or lack of symmetry. Kittler Exogenous pigmentation. The occurrence of a nodular growth within a congenital melanocytic nevus (CMN) is a troublesome event that raises suspicion for melanoma, especially in adults. Results: Three hundred and thirty CN were examined in a population of 276 children, aged from 6 months to 14 years. This type of birthmark occurs in an estimated 1% of infants worldwide; it is located in the area of the head and neck 15% of the time. We report a case in which dermoscopy was used in an attempt to avoid incisional biopsy. Atypical Nevus Prevalence. These nevi can occasionally manifest clinical morphologies . Lesions arise after birth and develop throughout life. The new classification has seven groups.

Kittler Congenital nevus combined. Kittler Hemangioma and Vasc Malformations. The center of the lesion is extremely dark and solid, without a visible pigment pattern by dermoscopy. The nevi join to form patches or plaques that often follow a pattern on the skin known as the "lines of Blaschko". Since most melanomas arising in association with smaller CMN develop along the DEJ, dermoscopy is an ideal instrument to help in the evaluation, screening, and monitoring of these nevi. Kittler Dermatofibroma. Chest and back are most commonly involved in men. When a giant or multiple congenital melanocytic nevi are present, follow-up is recommended. The usefulness of dermoscopy for patients with multiple nevi. A history of change within the lesion should be taken seriously as melanoma may arise in congenital melanocytic naevi, especially in giant naevi. . . 1,2 Few data are available regarding CN and the correlation between dermoscopy and reflectance confocal microscopy (RCM) throughout life stages. which was confirmed by dermoscopy.

Fried LJ, Tan A, Berry EG, et al. Kittler Clear cell acanthoma. In classic pathology, the term nevus is usually related to a benign hamartomatous proliferation programmed during embryologic life, i.e., a malformation consisting of tissue elements normally found at the corresponding site, but which are growing in a disorganized mass (Latin, naevus, birthmark) [].Thus, per definition, a nevus has to be of congenital origin, e.g., as a . Dermoscopy revealed predominantly homogeneous pattern with diffuse brownish areas, regular network at the periphery and numerous regularly distributed small dots .

Most CMN lesions affecting acral volar skin show characteristic dermoscopic features distinguishable from acral melanoma, and the combination of the crista dotted and parallel furrow patterns is the most common feature in acral CMN. The nevus can be present as a round or oval shaped macule, papule, or plaque . To date, this register has included more than 150 cases worldwide of pigmented lesions of the nail unit either present at birth or diagnosed during the first 5 years of life. Congenital nevi are well known precursor lesions of melanoma, the reported risk of development of melanoma ranging from 5% to 10%, presumably depending on the size of the lesion.

Lesions may also be noted on the extremities and the genitalia. Background: Congenital melanocytic nevi (CMN) are nevomelanocytic nevi which are present at birth. With the exception of congenital nevi of the lower extremities, 42, 43 reticular nevi correspond typically to junctional or lentiginous nevi. . Because prophylactic excision of all nevi is impractical, dermoscopic evaluation has a role in the clinical decision-making process. These birthmarks have a slightly increased risk of becoming skin cancer depending on their size. Dermoscopy of benign congenital nevi reveals a globular or homogenous pattern, black or brown dots and globules, small milia-like cysts within the globules, and terminal hairs.
