Ionizing radiation was used in the past for treatment of several benign cutaneous conditions, and particularly hemangiomas. Even though radiotherapy was generally effective, it significantly augmented the risk for malignancies, resulting in a consequent heavy decline of its use for benign conditions. However, radiation-induced neoplasia is still encountered in adult patients irradiated during childhood or adolescence. Read More

The clinical diagnosis of benign and malignant nail tumors can be difficult. Dermoscopy can provide a clue to the diagnosis but nail biopsy is the gold standard in establishing the diagnosis. Here, we report three cases of rare nail tumors, that is, onychopapilloma, onychomatricoma, and subungual osteochondroma, which were diagnosed on histopathology and managed surgically. Read More

Henna is a vegetable hair dye that can be used by individuals who are sensitized to oxidative dyes due to low allergenicity. The reported incidence of slate-grey facial dyspigmentation following the use of henna hair dye is extremely rare. This study aimed to identify the clinical, dermoscopic, and histopathological features of slate-grey facial dyspigmentation following the use of henna hair dye in Korean patients. Read More

Clinical examination is critical for the diagnosis and identification of response to treatment. It is fortunate that technologies are continuing to evolve allowing for augmentation of the classical clinical examination with non-invasive imaging modalities. This article will discuss emerging technologies with a focus on digital photographic imaging, confocal microscopy, optical coherence tomography (OCT) and high frequency ultrasound (HFUS) and several additional developing modalities.

Background And Objective: To ensure proper functioning of a Computer Aided Diagnosis (CAD) system for melanoma detection in dermoscopy images, it is important to accurately detect the border of the lesion. This paper proposes a method developed by the authors to address this problem.
Methods: The algorithm for segmentation of skin lesions in dermoscopy images is based on fuzzy classification of pixels and subsequent histogram thresholding. Read More

Background: Early accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and cutaneous squamous cell carcinoma (cSCC) are high-risk skin cancers which have the potential to metastasise and ultimately lead to death, whereas basal cell carcinoma (BCC) is usually localised with potential to infiltrate and damage surrounding tissue. Anxiety around missing early curable cases needs to be balanced against inappropriate referral and unnecessary excision of benign lesions. Read More

Background: Early accurate detection of all skin cancer types is essential to guide appropriate management, reduce morbidity and improve survival. Basal cell carcinoma (BCC) is usually localised to the skin but has potential to infiltrate and damage surrounding tissue, while cutaneous squamous cell carcinoma (cSCC) and melanoma have a much higher potential to metastasise and ultimately lead to death. Exfoliative cytology is a non-invasive test that uses the Tzanck smear technique to identify disease by examining the structure of cells obtained from scraped samples. Read More

Institute of Applied Health Research, University of Birmingham, Birmingham, UK, B15 2TT.
Background: Early accurate detection of all skin cancer types is important to guide appropriate management, to reduce morbidity and to improve survival. Basal cell carcinoma (BCC) is almost always a localised skin cancer with potential to infiltrate and damage surrounding tissue, whereas a minority of cutaneous squamous cell carcinomas (cSCCs) and invasive melanomas are higher-risk skin cancers with the potential to metastasise and cause death. Dermoscopy has become an important tool to assist specialist clinicians in the diagnosis of melanoma, and is increasingly used in primary-care settings. Read More

Background: Early accurate detection of all skin cancer types is important to guide appropriate management and improve morbidity and survival. Basal cell carcinoma (BCC) is usually a localised skin cancer but with potential to infiltrate and damage surrounding tissue, whereas cutaneous squamous cell carcinoma (cSCC) and melanoma are higher risk skin cancers with the potential to metastasise and ultimately lead to death. When used in conjunction with clinical or dermoscopic suspicion of malignancy, or both, reflectance confocal microscopy (RCM) may help to identify cancers eligible for non-surgical treatment without the need for a diagnostic biopsy, particularly in people with suspected BCC.

Melanoma is an increasingly common cancer in the United States, although mortality has likely stabilized. Diagnosis relies on a skilled practitioner with the aid of dermoscopy and initial local surgical management is a mainstay of treatment. Recent changes in staging emphasize continued use of sentinel lymph node biopsy to aid in prognostication although routine complete lymph node dissection has fallen out of favor. Read More

Background: Differential diagnosis of clinically atypical nevi (aN) and early melanomas (eMM) still represents a challenge even for experienced dermoscopists, as dermoscopy alone is not sufficient to adequately differentiate these equivocal melanocytic skin lesions (MSLs).
Objectives: The objectives of this study were to investigate what were the most relevant parameters for noninvasive differential diagnosis between eMM and aN among clinical, personal, and dermoscopic data and to evaluate their impact as risk factors for malignancy.
Methods: This was a retrospective study performed on 450 MSLs excised from 2014 to 2016 with a suspicion of malignancy. Read More

Background: Nail disorders comprise approximately 10% of all dermatological conditions.

Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease mainly affecting the axillary, inguinal and anogenital regions, and characterized by the presence of nodules, abscesses and sinus tracts and scarring. Clinical examination alone may underestimate the disease extension and severity. Some non-invasive skin imaging techniques such as ultrasound, magnetic resonance imaging, computed tomography, positron-emission tomography and dermoscopy, have been demonstrated to be useful in the diagnosis and management of HS.
