Melanonychia striata: clarifying behind the Black Curtain. A review on clinical evaluation and management of the 21st century.

Int J Dermatol 2019 Apr 21. Epub 2019 Apr 21.

Departments of Pediatrics, Laboratory Medicine, and Pathology, The University of Alberta, Edmonton, Alberta, Canada.

Melanonychia striata is characterized by a tan, brown, or black longitudinal streak within the nail plate that runs from the proximal nail fold to the distal part of the nail plate. Melanonychia striata is due to increased activity of melanocytes or melanocytic hyperplasia in the nail matrix with subsequently increased melanin deposition in the nail plate. The most common cause of melanonychia striata associated with melanocytic activation is ethnic melanonychia which occurs in dark-skinned individuals. Read More

A novel CDKN2A variant (p16 ) in a patient with familial and multiple primary melanomas.

Pigment Cell Melanoma Res 2019 Apr 18. Epub 2019 Apr 18.

Department of Dermatology, University of Utah Health Sciences Center, Salt Lake City, Utah.

Germline mutations in CDKN2A (p16) are commonly found in patients with family history of melanoma or personal history of multiple primary melanomas. The p16 tumor suppressor gene regulates cell cycle progression and senescence through binding of cyclin-dependent kinases (CDK) and also regulates cellular oxidative stress independently of cell cycle control. We identified a germline missense (c. Read More

Silencing of microRNA-27a facilitates autophagy and apoptosis of melanoma cells through the activation of the SYK-dependent mTOR signaling pathway.

J Cell Biochem 2019 Apr 17. Epub 2019 Apr 17.

Department of Dermatology, Hunan Provincial People's Hospital, The First Affiliated Hospital of Hunan Normal University, Changsha, P.R. China.

Melanoma is considered as an aggressive neoplastic transformation and featured with high metastatic potential. Although some studies have provided targets for novel therapeutic interventions, clinical development of targeted drugs for melanoma still remains obscure. Therefore, this study aims to identify the role of microRNA-27a (miR-27a) in autophagy and apoptosis of melanoma cells in regulating spleen tyrosine kinase (SYK)-mediated the mammalian target of rapamycin (mTOR) signaling pathway.

External validation and comparison of four confocal microscopic scores for melanoma diagnosis on a retrospective series of highly suspicious melanocytic lesions.

J Eur Acad Dermatol Venereol 2019 Apr 11. Epub 2019 Apr 11.

Centro Oncologico ad Alta Tecnologia Diagnostica, Azienda Unità Sanitaria Locale-IRCCS di Reggio Emilia, Italy.

Background: In-vivo reflectance confocal microscopy significantly improves melanoma diagnosis as compared to clinical/dermoscopic examination alone. Several confocal criteria have been described allowing to differentiate melanoma from nevi; by combining different criteria three pure confocal scores (Pellacani 2005, Segura 2009 and Pellacani 2012) and one mixed dermoscopic/confocal score (Borsari 2018) were constructed.

Objective: Our aim was to externally validate and compare the performance of these confocal scores. Read More

J Eur Acad Dermatol Venereol 2019 Apr 11. Epub 2019 Apr 11.

LABIOMEP, INEGI-LAETA, Faculdade de Engenharia, Universidade do Porto.

Background: The incidence rates of melanoma have risen to worrying levels over the last decade. Delayed diagnosis, due to faults on the detection stage, indicate the necessity of new aiding diagnosis techniques. Since metabolic activity is highly connected to neoplasia formation, a detection technique that focus its results on vascular responses, as IRT, seems to be a viable option. Read More

Validation of Whole-slide Digitally Imaged Melanocytic Lesions: Does Z-Stack Scanning Improve Diagnostic Accuracy?

J Pathol Inform 2019 21;10. Epub 2019 Feb 21.

Department of Pathology, Radboud University Medical Center, Nijmegen, The Netherlands.

Background: Accurate diagnosis of melanocytic lesions is challenging, even for expert pathologists. Nowadays, whole-slide imaging (WSI) is used for routine clinical pathology diagnosis in several laboratories. One of the limitations of WSI, as it is most often used, is the lack of a multiplanar focusing option. Read More

Department of Oral and Maxillofacial Surgery, Haldia Institute of Dental Sciences and Research, West Bengal University of Health Sciences, Haldia, West Bengal, India.

Gorlin-Goltz syndrome (GGS) also known as the nevoid basal cell carcinoma syndrome or the nevus-Bifid rib syndrome is an inherited autosomal dominant syndrome. It is caused by genetic alteration produced by a mutation in the "patched" tumor suppressor gene. This rare syndrome is characterized by basal cell carcinoma of skin, multiple odontogenic keratocyst and bifid ribs along with other features such as hypertelorism, sex organ abnormalities, palmar and/or plantar pits and calcification of falx cerebri.

Section of Dermatology, Department of Medicine, University of Chicago, Chicago, IL.

Lichen sclerosus (LS) is a chronic inflammatory dermatosis that classically presents as sclerotic, atrophic plaques in the genital region. We present a case of acrochordon with histological features of LS, clinically mimicking intradermal nevus, in a 53-year-old man with no prior history of LS. Our case highlights an unusual morphologic variant of acrochordon and illustrates the role of chronic pressure and occlusion in the development of secondary features of LS. Read More

Department of Biopathology, Centre Léon Bérard, Lyon, France.

A girl, born with a posterior  lumbosacral giant congenital nevus, developed a central nodule that expanded over a period of 14 months into a 10-cm pedunculated mass. Histological analysis of the mass revealed melanoma of myxoid, small round-cell type with areas of  rhabdomyosarcomatous  transformation confirmed by immunohistochemistry. RNA sequencing identified an in-frame SASS6(e14)-RAF1(e8) fusion in both components and the nevus. Read More

Staged Mosaic Punching Excision of a Kissing Nevus on the Eyelid.

Aesthetic Plast Surg 2019 Apr 1. Epub 2019 Apr 1.

Department of Plastic and Reconstructive Surgery, Hanyang University Seoul Hospital, Hanyang University College of Medicine, Seoul, South Korea.

Background: A congenital divided nevus, also known as kissing nevus, is a type of congenital compound nevus that affects equal areas of the upper and lower eyelids. The edges of the nevus touch or "kiss" during closure of the lids, owing to its extension to the lid margins. Multiple treatment modalities, such as dermabrasion, cryotherapy, primary closure after excision, and skin grafts, have been proposed; however, complications such as recurrence, ectropion, skin color mismatch, and scar contractures are known to occur.

Large-giant congenital melanocytic nevi have been well characterized clinically, yet questions remain about the heterogenous phenotypes observed. Martins da Silva et al. (2018) highlight the genotypic diversity between "classic" and "spilus-like" congenital melanocytic nevi by analyzing multiple biopsy sites and matching satellite nevi. Read More

Division of Plastic and Reconstructive Surgery, Keck School of Medicine, University of Southern California.

Congenital and pediatric nasal lesion resection and their reconstructive outcomes are not well studied. A surgeon must consider the site, size, depth, etiology, age, and effect on future function (including growth). As such, it is important to contrast the differences between the adult's and child's nose. Read More

Cureus 2019 Jan 8;11(1):e3849. Epub 2019 Jan 8.

Oral and Maxillofacial Surgery, King Saud University, Riyadh, SAU.

Gorlin-Goltz syndrome (GGS) is an infrequent multisystemic disease with an autosomal dominant inherited disorder characterized by the presence of multiple keratocystic odontogenic tumors (KCOT) in the jaws, multiple basal cell nevi carcinomas, and skeletal abnormalities. Early diagnosis of Gorlin-Goltz syndrome is essential as it may progress to aggressive basal cell carcinomas and neoplasias. Gorlin-Goltz syndrome has rarely been reported in Saudi Arabia. Read More
