Congenital melanocytic nevus (CMN) is a benign proliferation of cutaneous melanocytes that arises as the result of abnormal growth, development, or migration of melanoblasts (1) . They are clinically evident at birth and usually produce a high degree of stress among physicians and parents due to the risk of malignant transformation. In spite that the actual lifetime risk of developing melanoma from a small or medium-sized CMN is unknown, and some reports estimate this risk to be less than 5%, any recent-onset palpable nodule in a CMN may be worrisome...

Childhood vitiligo differs from adult-onset vitiligo for several features including increased incidence of the segmental variant, higher prevalence of halo nevi, and more common family history for autoimmune diseases and atopic diathesis. The major differential diagnoses are the postinflammatory hypomelanoses for nonsegmental vitiligo and nevus depigmentosus for segmental vitiligo. From a therapeutic standpoint, early awareness of the diagnosis seems to correlate with a good treatment outcome in this age group...

Nevus lipomatosus cutaneous superficialis (NLCS) is an uncommon lesion characterized by ectopic adipose tissue in the dermis and can be generalized or localized. It presents as a soft skin colored to yellowish papules or cerebriform plaques occurring usually on the buttock or thigh in a segment distribution. We report a case of NLCS in 38-year-old female, which was treated using the ultrapulse mode CO2 Laser. We describe the scientific logic and clinical results of using the ultrapulse mode in relation to the pathology of NLCS...

Distinguishing benign acral nevi from small early acral melanomas may be challenging in certain cases. Dermoscopy is a noninvasive imaging technique that can help clinicians better visualize deeper lesion structures and thus more easily differentiate benign nevi from melanoma. We report the case of a 13-year-old girl with a changing dark brown to black macule with a central papular component on the volar surface of the right third finger. Dermoscopy revealed asymmetrically distributed irregular black blotches on a bluish-black background...

Oculodermal melanocytosis, also known as Nevus of Ota, is a hamartomatous melanocytic nevus of dermal melanocytes. It presents as a bluish grey patch on the face, which may be congenital or acquired involving the area of distribution of the ophthalmic and maxillary branches of the trigeminal nerve. The nevus can be unilateral or bilateral, and, in addition to skin, it may involve ocular and oral mucosal surfaces. It is a rare disorder and the ocular complications, such as glaucoma and melanoma, may be vision or life-threatening...

Verrucous epidermal nevi are hamartomatous lesions of the epidermis that, unlike other epidermal nevi (such as sebaceous nevus or nevus comedonicus), are rarely associated with malignant neoplasms. The majority of squamous cell carcinoma develop in linear or multiple epidermal nevus and rarely in solitary epidermal nevus. In general, the prognosis is favorable. We report a case of well-differentiated invasive squamous cell carcinoma arising from a multiple verrucous epidermal nevus. Although there is no consensus on prophylactic removal of epidermal nevus, its removal and biopsy should be considered if changes occur...

We report a case of nevus lipomatosus cutaneous superficialis of Hoffman-Zurhelle (NCLS), with multiple lesions, in a ten-year-old child. The NLCS is considered rare. The classical clinical presentation is characterized by multiple skin-colored or yellowish papules and nodules, which can have a linear distribution. Histologically, it is characterized by the presence of mature ectopic adipocytes in the dermis. The main therapeutic option is surgical excision. The classical Nevus lipomatosus cutaneous superficialis is reported in this case...

Phacomatosis pigmentovascularis is a rare syndrome, defined as the simultaneous presence of vascular nevus and melanocytic nevus in the same patient. We report the case of a 53-year-old woman presented with dermal melanosis and extensive vascular nevus, which match the typical manifestations of phakomatosis pigmetovascularis of cesioflammea type, according to Happle's classification. The rare occurrence of this genodermatosis and the clinical exuberance of the skin lesions motivated this case report.

Elastoma is a connective tissue nevus characterized by changes in elastic fibers. It can be congenital or acquired, and is usually diagnosed before puberty. Associated with osteopoikilosis, it is known as Buschke-Ollendorff syndrome. Histopathology with specific staining for elastic fibers is critical for a diagnostic conclusion. This report describes the case of a 7-year-old male patient with lesions diagnosed as elastoma, with absence of bone changes in the radiological imaging. This study aims to report the clinical presentation and histological examination of such unusual disease...

We aimed to investigate the efficacy and safety of using the 1064-nm Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser (QSNYL) for skin rejuvenation in patients with Nevus of Ota. A retrospective, randomized, split-faced, clinical study was conducted. Twenty-nine patients with unilateral moderate to severe Nevus of Ota were enrolled. The participants completed 3-13 sessions of QSNYL treatments 3-6 months apart. Two independent physicians compared the treated and untreated sides of the face to evaluate the clearance of Nevus of Ota, the wrinkle severity rating scale (WSRS), the global aesthetic improvement scale (GAIS), and adverse event reporting...

There are several therapeutic options to treat congenital melanocytic nevi. The motivations for the treatment of small- to medium-sized congenital nevi located on the face or other sensitive areas are frequently cosmetic. The choice of therapy depends on the operator's expertise and on the likelihood of improved cosmesis. We report a case of a medium-sized congenital nevi located on the lower eyelid, successfully treated with a combination of ablative lasers with a single surgical procedure. We achieved an excellent clinical and cosmetic result...

Mutations in the fibroblast growth factor-receptor gene 2 (FGFR2) gene have been implicated in numerous diseases, including nevus comedonicus (NC) and naevoid acne that have somatic missense mutations in FGFR2 in the affected tissue. A patient presented in our department with unusual, innumerable large comedones throughout his back reminiscient of NC, as well as multifocal hidradenitis suppurativa and acne. Topical and systemic treatments were unsuccessful. Whole exome sequencing of blood-derived DNA detected a germline mutation in FGFR2 that was predicted to be damaging...

Expanded local flaps and skin grafts (expanded/nonexpanded) are a common approach for reconstructing medium (1.5-20 cm) and large (>20 cm) divided nevi of the eyelids. However, this approach does not often provide a satisfactory cosmetic result, particularly in Asian patients, because of different skin types. We recently devised a new surgical procedure using an extended cheek flap and tissue expander for the medium-sized divided nevus of the eyelids. The upper and lower eyelids are concurrently reconstructed by divided flaps...

Accumulating evidences indicated that plasmacytoma variant translocation 1 (PVT1) plays vital roles in several cancers. However, the expression, functions, and clinical values of PVT1 in melanoma are still unknown. In this study we measured the expression of PVT1 in clinical tissues and serum samples and explored the diagnostic value of PVT1 for melanoma and the effects of PVT1 on melanoma cell proliferation, cell cycle, and migration. Our results, combined with publicly available PVT1 expression data, revealed that PVT1 is upregulated in melanoma tissues compared with nonneoplastic nevi tissues...
