    A case report of disappearing pigmented skin lesions associated with pembrolizumab treatment for metastatic melanoma.
    Br J Dermatol 2017 Jan 28. Epub 2017 Jan 28.
    Memorial Sloan Kettering Cancer Center, Department of Medicine, Dermatology Service.
    Pembrolizumab is an immune checkpoint inhibitor that targets the programmed cell death (PD)-1 receptor. Common cutaneous adverse side effects of PD-1 inhibitors include maculopapular rash, pruritus, vitiligo, and lichenoid skin and mucosal reactions. Here, we describe a man in his sixties with metastatic melanoma treated with pembrolizumab who subsequently developed fading or disappearance of pigmented skin lesions, lightening of the skin, and poliosis of the eyebrows, eyelashes, and scalp and body hair.

    Melanoma: clinical and dermoscopic diagnosis.
    G Ital Dermatol Venereol 2017 Jan 24. Epub 2017 Jan 24.
    Dermatology Unit, University of Campania Luigi Vanvitelli, Naples, Italy.
    Missing the diagnosis of a melanoma is the worst dermatologist nightmare, especially when melanomas have a non-alarming clinical appearance and imitate a completely benign lesion. The use of dermoscopy has provided an effective tool to facilitate the differential diagnosis and to increasingly allow an early diagnosis of melanoma. The aim of this article is to summarize the most recent and important clinical and dermoscopic pearls to recognize melanoma at the earliest stages of its development. Read More

    Update on dermoscopy of Spitz/Reed naevi and management guidelines by the International Dermoscopy Society.
    Br J Dermatol 2017 Jan 24. Epub 2017 Jan 24.
    Dermatology Unit, Second University of Naples, Naples, Italy.
    Spitzoid lesions represent a challenging and controversial group of tumours, in terms of clinical recognition, biologic behavior and management strategies. Although Spitz naevi are considered benign tumours, their clinical and dermoscopic morphologic overlap with spitzoid melanoma renders the management of spitzoid lesions particularly difficult. The controversy deepens because of the existence of tumours that cannot be safely histopathologically diagnosed as naevi or melanomas (atypical Spitz tumours). Read More

    Dermoscopy of Papular Epidermal Nevus with Skyline Basal Cell Layer.
    Pediatr Dermatol 2017 Jan 23. Epub 2017 Jan 23.

    Nanostructured Lipid Carrier for Topical Application of N-Acetyl Glucosamine.
    Adv Pharm Bull 2016 Dec 22;6(4):581-587. Epub 2016 Dec 22.
    Drug Applied Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.
    Purpose: Hyperpigmentation occurs when melanin is overproduced in certain spots on the skin and is one of the most challenging skin conditions to treat. Although it is usually harmless, for cosmetic reasons, it is dreadfully bothersome to those who undergo it. It was reported that N-acetyl-glucosamine (NAGA) prevents melanin synthesis and alters the expression of numerous genes related to pigmentation. Read More

    Department of Experimental and Clinical Medicine, Institute of Dermatology, University of Udine, Udine, Italy.
    Background: Dermoscopy of granuloma annulare has been investigated by several studies, but none of them took into account the variability of dermoscopic findings according to clinical characteristics and/or histological subtype.

    Objective: To describe the dermoscopic features of classic granuloma annulare and seek possible dermoscopic clues related to specific clinical findings/histological subpatterns.

    Methods: A representative dermoscopic image of a target lesion (the most active lesion underwent histological examination) was retrospectively assessed for the presence of specific morphological findings, correlating them with clinical variables, i. Read More

    Incorporating Colour Information for Computer-Aided Diagnosis of Melanoma from Dermoscopy Images: A Retrospective Survey and Critical Analysis.
    Int J Biomed Imaging 2016 19;2016:4868305. Epub 2016 Dec 19.
    School of Computing Science, Simon Fraser University, Burnaby, BC, Canada.
    Cutaneous melanoma is the most life-threatening form of skin cancer. Although advanced melanoma is often considered as incurable, if detected and excised early, the prognosis is promising. Today, clinicians use computer vision in an increasing number of applications to aid early detection of melanoma through dermatological image analysis (dermoscopy images, in particular). Read More

    Vascular Patterns in Cutaneous Ulcerated Basal Cell Carcinoma: A Retrospective Blinded Study Including Dermoscopy.
    Acta Derm Venereol 2017 Jan 17. Epub 2017 Jan 17.
    Section of Dermatology, Department of Biomedical Science and Human Oncology, University of Bari, 11, Piazza Giulio Cesare, Bari, IT-70124 Bari, Italy.
    The aim of this retrospective study was to determine the type and prevalence of vascular patterns in the ulcerated and non-ulcerated portions of histologically proven basal cell carcinomas (BCCs) and correlate them with other dermoscopic and clinical features, including the clinically supposed diagnosis. Three authors retrospectively collected 156 clinical and 156 dermoscopic digital images of ulcerated BCCs (histologically confirmed); each image was blindly evaluated by 2 other authors, who did not know the histological diagnosis. Seventeen lesions were completely ulcerated, while 139 lesions presented ulcerated and non-ulcerated portions. Read More
