Nevus sebaceus is a hamartoma of the sebaceous gland that occurs congenitally, from which various secondary tumors can arise with a prevalence of 5%-6%. Benign neoplasms commonly arise from nevus sebaceous, but they have a very low malignant potential. Two neoplasms may occasionally arise within the same lesion, but it is rare for three or more neoplasms to occur in a nevus sebaceus simultaneously. A 61-year-old male patient was admitted to our hospital for a 4 cm×2.5 cm growing tumor in a verrucous form arising within a periauricular nevus sebaceus in the post auricle of the left ear that had developed 30 years earlier...

Nevus sebaceus of Jadassohn is a congenital tumour affecting the scalp and face. It is usually presented as a pigmented patch or plaque. It is a complex cutaneous hamartoma which involves pilosebaceous follicle, epidermis and adnexal structures. Tumours that arise from nevus sebaceous are basal cell carcinoma, syringocystadenoma papilliferum, trichoblastoma and hidradenoma. The progression and frequency of the tumour increase with the age. Here we present a case of pigmented trichoblastoma over the external nose...

We present a 4-month-old infant with an eczematous halo around a congenital melanocytic nevus. After diagnostic excision, histopathologic examination revealed a Meyerson's nevus. This is a benign skin tumour that may show clinical signs of melanoma. It is therefore important to include Meyerson's nevus in the differential diagnosis of melanoma.

The use of pedicled and free flaps for tissue transfer and coverage has become a common practice in modern plastic surgery. An area that presents considerable challenge for tissue coverage is the groin. Defects in this area are complicated by issues such as prior surgery; scar contracture; extension of the defect beyond the borders of the groin; radiation damage; high probability of infection; and involvement of vital underlying structures, the genitalia, and perineal and perianal area. Therefore, the choice of donor site and flap usage is often difficult...

Persistent embryonic veins represent a major source of venous hypertension and morbidity in venous malformation syndromes, such as Klippel-Trénaunay syndrome and congenital lipomatous overgrowth, vascular malformations, epidermal nevus, and skeletal deformities syndrome. Surgical stripping and phlebectomy are the most commonly reported alternatives to compression therapy for refractory cases. These techniques, although effective in those patients who meet the necessary anatomic criteria, can be associated with bleeding, wound-related complications, and recurrence...

We report the case of a 12-year-old girl with a smooth muscle hamartoma of the right index finger. Smooth muscle hamartoma (SMH) is a congenital, relatively common disorder typically with predominance of autochthonal arrector pili muscles. An SMH can also rarely originate from smooth muscles of vessels in palmoplantar skin with the absence of pilosebaceous units. Because of overlapping histological features, the possibility of Becker's nevus being identical or associated with SMH has often been suspected by some authors...

Eyebrows play an important role in face expression and facial mimics by virtue of muscle contraction. Defects or deformity of the eyebrows result in abnormal facial expressions, and may lead to aesthetic issues for patients. The objective of this study is to report the case of a patient, with a congenital skin pigmented nevus at the right side of the eyebrow treated with direct surgical resection and followed by immediate reconstruction of the eyebrow with a V-Y advancement pedicle flap based on the orbicularis oculi muscle...

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...
