Pain is a common side-effect of dermatological laser procedures. Non-invasive anaesthetic drugs and anaesthetic procedures can be used to provide pain relief and increase patient satisfaction and treatment efficacy. However, it remains unclear which method provides the best pain relief. The objective of this systematic review was therefore to assess the efficacy and safety of non-invasive anaesthetic methods during dermatological laser procedures. A systematic literature search was conducted. Randomized and non-randomized controlled clinical trials (RCTs and CCTs) were included...

BACKGROUND: Epidermal nevi are benign hamartomatous growths of the skin that present at birth and develop in early childhood often linearly along the "lines of Blaschko". Verrucous linear epidermal nevi are the most common epidermal nevi and often are located on the trunk or extremities. There is minimal evidence regarding vulvar involvement and subsequent management of the associated cosmetic deformity in this anatomic location. CASE: An 11 year-old menarchal female who underwent full-thickness dermal excision of a 9...

In most cases of cutaneous melanoma, ultraviolet (UV) radiation is recognized as a prominent risk factor. Less is known regarding the mechanisms of mutagenesis for melanoma arising in sun-protected sites, such as acral and mucosal melanoma. Acral and mucosal melanoma share many common features, including a late age of onset, a broad radial growth phase with prominent lentiginous growth, the presence of field cancerization cells, and, in most cases, lack of a precursor nevus. In addition to early chromosomal instability, many of the same genes are also involved in these two distinct melanoma subtypes...

We report 7 cases of hitherto undescribed keratotic papillary plaques of uncertain etiology involving the gingiva. All 7 cases presented on the anterior maxillary attached gingiva of patients in the second decade. The lesions were asymptomatic and 86% (6 of 7 cases) presented in a bilateral symmetric distribution. Microscopically, the lesions exhibited parakeratosis and papillary acanthosis with parakeratin-filled crypts. No specific etiology such as a factitial habit or a common exogenous agent has been identified...

Fibroblastic connective tissue nevus (FCTN) is a rare and recently described neoplasm of fibroblastic/myofibroblastic lineage. We report a case of a 1-month-old healthy male infant who presented with a dermal plaque on the upper chest since birth. A punch biopsy demonstrated a dermal spindle-cell neoplasm with variable smooth muscle actin positivity and negative staining for CD34, consistent with myofibroma. Over the course of the next year, the remaining lesional tissue exhibited clinical softening and a surgical excisional specimen revealed histologic findings distinct from the original biopsy...

The congenital melanocytic nevus is a pigmented melanocytic lesion that presents at birth or shortly thereafter. It is commonly described on the skin, usually on the trunk and extremities. Only five intraoral cases of congenital melanocytic nevi have been described in the English literature. A nevus spilus (speckled lentiginous nevus) is a clinical variant of congenital melanocytic nevus. The authors present the case of a 19-year-old male with an intraoral nevus spilus. The anterior mandibular gingiva exhibited multiple speckled, pigmented papules and macules on a thickened, hyperplastic macular background...

Nevi and melanocytic proliferations are known to appear in multiple extracutaneous sites, including lymph nodes and meninges. We report a case of an anterior mediastinal mass in a patient with a giant congenital nevus and neurofibromatosis type I. Histologically, the tumor was found to be a malignant melanoma in the thymus arising in association with a nevus that involved most of the thymic tissue. There was no sign of cutaneous melanoma on skin examination. We suggest that the tumor originated from the benign nevus in the thymus, a rare extracutaneous location for nevi and malignant melanoma...

BACKGROUND: 5-hydroxymethylcytosine (5-hmC) is an epigenetic marker detectable through immunohistochemistry (IHC) that has been shown to distinguish benign nevi from melanoma with high sensitivity and specificity. The purpose of the study was to explore its diagnostic utility in a subset of histologically challenging, heavily pigmented cutaneous melanocytic neoplasms. METHODS: 5-hmC IHC was performed on 54 heavily pigmented melanocytic tumors. Semi-quantitative analysis of immunoreactivity was correlated with clinical, pathologic, and follow-up data...

PURPOSE: To determine whether some of the most often used uveal melanoma cell lines resemble their original tumor. METHODS: Analysis of the literature, patient charts, histopathology, mutations, chromosome status, HLA type, and expression of melanocyte markers on cell lines and their primary tumors. We examined five cell lines and the primary tumors from which they were derived. RESULTS: Four of the five examined primary tumors were unusual: one occupied the orbit, two were recurrences after prior irradiation, and one developed in an eye with a nevus of Ota...

Soblet et al. describe cis mutations in TEK/Tie-2 in blue rubber bleb nevus and sporadic vascular malformations. This suggests that the remaining normal allele is required for the phenotype. Second, it suggests therapeutic approaches to treatment signal transduction inhibition.

A reliable, fast, and non-invasive determination of melanoma thickness in vivo is highly desirable for clinical dermatology as it may facilitate the identification of surgical melanoma margins, determine if a sentinel node biopsy should be performed or not, and reduce the number of surgical interventions for patients. In this work, optical coherence tomography (OCT) and high frequency ultrasound (HFUS) are evaluated for quantitative in vivo preoperative assessment of the skin infiltration depth of melanocytic tissue...

A 26-year-old African American man with a history of depression and tuberculosis presented to the gastroenterology department after several months of rectal pain with bowel movements. Colonoscopy revealed hyperpigmentation in the distal rectum and internal hemorrhoids, which resulted in a diagnosis of blue nevi. This is only the third known description of a blue nevus involving the gastrointestinal mucosa.

In animal models, IL-12 and IL-23 participate in the development of malignant neoplasms of keratinocytes. However, the role of these cytokines in pigmented lesion development and their progression to melanoma has received little attention. IL-12p35, IL-23p19, and IL-12/IL-23p40 knockout mice on a C3H/HeN background, subjected to a melanomagenesis protocol, demonstrated profound differences in susceptibility to nevus initiation, transformation, tumorigenicity, and metastatic potential. IL-23 was found to be essential for melanocyte homeostasis, whereas IL-12 supported nevus development...

The co-occurrence of blue rubber bleb nevus syndrome (BRBNS) and ventricular septal defects is rare. Here we present a case of BRBNS in a 15-year-old boy who was born with multiple cavernous hemangiomas and a ventricular septal defect. Examinations revealed the presence of hemangioma lesions in the subcutaneous and mucosal tissues as well as in the cerebrum, nasopharynx, tongue, esophagus, gastric body, sigmoid colon and adrenal gland. Combined imaging modalities played an important role in the diagnosis of hemangioma lesions...
