BACKGROUND: Nevus of Ota is a rare disease most frequently found in Asians. It presents clinically as a bluish gray hyperpigmentation of one side of the face. Transformation into melanoma and glaucoma are the main risks. The appearance of vitiligo lesions with poliosis within a nevus of Ota is exceptional. PATIENTS AND METHODS: A 22-year-old female patient with a nevus of Ota consulted for depigmentation of the eyelashes. Physical examination revealed hyperpigmentation in the right orbitofrontal part of her face, achromic macules and eyelash poliosis...

Integra dermal regeneration template has been well established in treating deep extensive burns, but there are very few cases reported of treating large full-thickness skin defects such as giant nevi. Apart from psychological and cosmetic burdens, the giant congenital nevus carries increased risk of malignant alteration. We present the case of a 9-year-old girl with a giant congenital nevus on her left lower leg. A total excision was done and she was successfully treated with Integra (LifeSciences Corp, Plainsboro, NJ)...

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 with expanded skin flap (skin expanders). The aim of this study is to report the author's 40 years of experience with cases requiring at least 4 serial excisions to complete the treatment. Serial resection is an effective, safe, and simple technique that requires a lot of patience...

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. However, proliferative nodules are typically benign, regression is common and there is minimum risk of malignization. We present a new case of proliferative nodule in melanocytic nevi with features of deep penetrating nevus.

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-year period. To the best of our knowledge, there are no published similar studies on large congenital melanocytic nevus in South America. Methods: Our prospective cohort included only patients with congenital nevi ≥20cm...

The purpose of this paper is to highlight the risk of early malignant transformation in infants with giant congenital melanocytic nevi (GN) and demonstrate the potential for earlier intervention with aggressive surgery. We describe the case of a child born with a GN who developed a metastatic melanoma early in life, despite early commencement of resection of the nevus. This is contrasted against a second case of a child in which a more radical management was conducted. Despite early commencement of serial resection of the GN, the first child in this series died of metastatic melanoma prior to complete excision of the nevus...

Inflammatory linear verrucous epidermal nevus (ILVEN) is a relatively rare disorder with an onset at early age, consisting of pruritic linear papules and/or plaques and histologic features resembling psoriasis or lichenoid dermatitis. The disease is a version of mosaicism caused by somatic mutations. ILVEN belongs to the heterogeneous group of congenital hamartomas of embryonal ectodermal origin, as a variant of verrucous epidermal nevus, representing approximately 5% of all epidermal nevi, with predominance in females and with general therapeutic resistance...

Nevus sebaceus of Jadassohn, a congenital cutaneous hamartoma, has the potential to develop into various epidermal adnexal-origin neoplasms. While the most common neoplasms are trichoblastoma or syringocystadenoma, proliferating trichilemmal cysts are exceptionally rare. We report a case of a 63-year-old Cuban male with a giant proliferating trichilemmal cyst arising from a nevus sebaceus on the right shoulder which had been growing for 30 years. Proliferating trichilemmal cysts arising from nevus sebaceus cases are difficult to diagnose clinically and histologically since they are very rare and have not been defined by exact diagnostic criteria...

Abnormal findings on routine skin exams are common and can be a source of unnecessary medical workup if a clinician is unfamiliar with the finding. Sebaceous nevi are rare skin lesions that are most often benign but may be associated with a multiorgan syndrome or local skin cancer. Dermatologists and primary care physicians may encounter these on routine exams and thus must be comfortable with diagnosis and management. We present the clinical characteristics of a benign sebaceous nevus to help aid in diagnosis of these lesions and outline suggestions for appropriate management options...

Proteus syndrome is a rare sporadic disorder that appears with localized macrosomia, congenital lipomatosis, and slow flow vascular malformations, connective tissue nevus, and epidermal nevus. There are usually some manifestations at birth. The vascular abnormalities that have been reported in Proteus syndrome are capillary and slow flow venous malformation. We report a case of a 10-year-old boy with confirmed Proteus syndrome characterized by high flow vascular malformation (arteriovenous [AV] malformation) unlike the usual vascular malformations seen in this syndrome...

Benign melanocytic nevi are slowly growing acquiredor congenital tumors with varied morphology,commonly encountered in dermatology clinics. Anytumor with rapid clinical growth must be assessedcarefully in order to exclude malignancy. We report awoman with a histopathologically benign intradermalnevus that presented as a rapidly evolving largecutaneous mass on the ear. Owing to the discrepancybetween the clinical and histopathological findings,an extensive histopathological work-up involvingmany deeper sections, immunohistochemical stains,and fluorescent in situ hybridization (FISH) analysiswas conducted in order to rule out malignancy...

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...

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...

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...
