Becker nevus on the lower limb: case report and review of the literature

Follicular Becker's nevi: A case series and review of literature

The follicular variant of Becker's nevus is an under-reported entity. We present the rare occurrence of follicular Becker's nevus in 7 patients, confirmed through dermoscopy and histopathological examination. Dermoscopy shows perifollicular hypopigmentation surrounded by a well-defined net-like pigmentation corresponding clinically to the presence of folliculocentric macules. Histology shows prominent basal and suprabasal melanization surrounding the follicle, corresponding to well-defined net-like pigmentation seen on dermoscopy. However, the melanization does not extend along the entire length of the follicular epithelium leading to perifollicular hypopigmentation on dermoscopy. Though biopsy is confirmatory, it is not usually necessary.

A case of multiple, bilateral Becker's Nevi of the trunk and lower extremities in a young girl: A case report

A Becker's nevus typically appears as a single unilateral, well-demarcated, hyperpigmented patch over the upper trunk during adolescence. It uncommonly presents as multiple and bilateral patches and rarely involves a lower extremity. We describe the unusual case of a child with multiple, bilateral Becker's nevi of the trunk and lower extremities present since birth.

Becker's Nevus Coexisting with Morphea: A Rare Case Report

Becker's nevus (BN) is an acquired unilateral hyperpigmented hairy macule, whereas morphea is a chronic connective tissue disease of unknown etiology, characterized by skin thickening with increased quantities of collagen in the indurated lesion, usually involving the upper trunk and proximal extremity. The occurrence of both disease in the same anatomical site and individual was not reported previously. We report this rare case in a 17-year-old, Indian girl and was diagnosed after clinical histopathology and dermoscopic correlation. Morphea can be an interesting incidental occurrence within a large plaque of BN.

Unconventional use of intense pulsed light

According to the literature, intense pulsed light (IPL) represents a versatile tool in the treatment of some dermatological conditions (i.e., pigmentation disorders, hair removal, and acne), due to its wide range of wavelengths. The authors herein report on 58 unconventional but effective uses of IPL in several cutaneous diseases, such as rosacea (10 cases), port-wine stain (PWS) (10 cases), disseminated porokeratosis (10 cases), pilonidal cyst (3 cases), seborrheic keratosis (10 cases), hypertrophic scar (5 cases) and keloid scar (5 cases), Becker's nevus (2 cases), hidradenitis suppurativa (2 cases), and sarcoidosis (1 case). Our results should suggest that IPL could represent a valid therapeutic support and option by providing excellent outcomes and low side effects, even though it should be underlined that the use and the effectiveness of IPL are strongly related to the operator's experience (acquired by attempting at least one specific course on the use of IPL and one-year experience in a specialized centre). Moreover, the daily use of these devices will surely increase clinical experience and provide new information, thus enhancing long-term results and improving IPL effectiveness.

Epidermal nevi

Nevi or nests of cells may be made up of a variety of cell types. The cell types that live in the epidermis include epidermal cells or keratinocytes, sebaceous glands, hair follicles, apocrine and eccrine glands, and smooth muscle cells. This article discusses epidermal or keratinocyte nevi, nevus sebaceous, nevus comedonicus, smooth muscle hamartomas, and inflammatory linear verrucous epidermal nevi. Syndromes associated with epidermal nevi are also reviewed.
