Squamous cell carcinoma (SCC) of the nail apparatus is a rare malignant tumor that usually originates underneath the nail plate and grows slowly with possible bone invasion. The etiology remains unknown, although a strong association with different conditions, such as high-risk human papillomavirus (HPVs), trauma, or radiation exposure has been demonstrated. Nail SCC is called "the great mimicker nail tumor" because different clinical presentations may coexist, resembling benign or malignant nail lesions...

Patients with multiple atypical nevi are at higher risk of developing melanoma. Among different techniques, sequential digital dermatoscopic imaging (SDDI) is a state-of-the art method to enhance diagnostic accuracy in evaluating pigmented skin lesions. It relies on analyzing digital dermatoscopic images of a lesion over time to find specific dynamic criteria inferring biologic behavior. SDDI can reduce the number of necessary excisions and finds melanomas in an early-and potentially curable-stage, but precautions in selecting patients and lesions have to be met to reach those goals...

Teledermatology is a useful alternative where specialized dermatological assistance is not available and has been used successfully to support health professionals in a wide range of settings worldwide, in either an asynchronous store-and-forward format or a real-time video conferencing format. Teledermoscopy, which includes dermoscopic images in the teleconsultation, is another addition that improves remote assessments of pigmented lesions. A more recent variant is mobile teledermoscopy, which uses a smartphone to deliver the same type of service...

Background: Dermoscopy is a fundamental method in the examination of melanocytic neoplasms. Limited data exist about the dermoscopic features of ocular pigmentations (OPs). Objectives: We aimed to investigate the usefulness of dermoscopy in the examination of OPs. Methods: Dermoscopic images of OPs of 20 consecutive patients were recorded. Impression cytology (IC) was performed to these lesions. Dermoscopic images were evaluated for specific dermoscopic structures and patterns without knowing the cytological examination results...

Recognition of facial lentigo maligna (LM) is often difficult, particularly at early stages. Algorithms and multivariate diagnostic models have recently been elaborated on the attempt to improve the diagnostic accuracy. We conducted a cross-sectional and retrospective study to evaluate dermatoscopic criteria aiding in diagnosis of flat pigmented facial lesions (FPFL). We examined 46 FPFL in 42 Caucasian patients and found that 4 of 20 dermatoscopic criteria reached the significance level required for features indicating malignancy namely, hyperpigmented follicular openings, obliterated follicular opening, annular-granular structures, and pigment rhomboids...

Dermatological paraneoplastic syndromes are a group of cutaneous diseases associated with malignancy, but not directly related to the primary tumor itself or to its metastases. It is of utmost importance for the dermatologist to recognize the major cutaneous paraneoplastic syndromes to diagnose the underlying tumors that trigger them as early as possible. In this overview, skin conditions that are highly correlated with malignancy, whose recognition implies a mandatory investigation of internal cancer, are described...

We present a case of subcutaneous nodular amyloidosis mimicking a pilar cyst. Further evaluation led to the diagnosis of malignant systemic light-chain amyloidosis. The epidemiology and histopathological features of light-chain amyloidosis with cutaneous involvement are reviewed, as well as current recommendations for initial evaluation.

Lichen planus-like keratosis (LPLK) is an involuting cutaneous lesion often presenting between the fifth and seventh decades of life. These lesions typically appear abruptly as a solitary macule, papule, or plaque that continuously evolves as it undergoes regression. Clinical and dermoscopic features of LPLK can mimic both benign and malignant lesions, often prompting biopsy for accurate diagnosis. We describe a case of LPLK developing in a patient with a history of multiple skin cancers, including melanoma...

Sarcoidosis is a multisystemic granulomatous disease of unknown causes, and cutaneous sarcoidosis (CS) is an early manifestation of the disease. Dermoscopy has gained increasing interest in the past few years as an aid in the clinical diagnosis of inflammatory and infectious skin manifestations. We present a case report about a single, erythematous, and asymptomatic plaque on the face with unexpected dermoscopy characteristics of CS. Learning points: CS on the face of a therapy-resistant actinic keratosis should be considered a differential diagnosis...

Background: Warts are one of the most common infections in humans. Plantar warts are a subtype of non-genital warts, and several procedures and topical treatments have been used in its treatment. Cryotherapy is one of the most popular modalities, but it is time-consuming and remission rates vary in different studies. CO2 laser was the first laser used for treating warts. To date, no clinical trial has been done to compare CO2 laser with cryotherapy in the treatment of plantar warts. Patients and Methods: This randomized controlled trial was performed in order to compare the efficacy and number of sessions needed to treat plantar warts in 60 patients who had received no previous treatment in the previous 3 months...

Bullous pemphigoid (BP) is described as a subepidermal blistering disorder, which is commonly reported among the elderly, particularly those older than 60 years of age. In this report, we present the case of a 41-year-old female patient with BP lesions that were initially detected at the site of Hijama therapy with a subsequent generalized spread. Punch biopsy from the lesions and perilesional direct immunofluorescence (DIF) demonstrated features of BP. The anti-BP180 level was 178 RU/mL, and the anti-BP230 level was negative...

Vulvar melanoma is a rare and deadly cancer in women, and the prognosis is often poor. There are limited studies on the dermoscopic features of vulvar melanoma. Described criteria include the presence of blue, gray, or white colors. Herein we present the clinical and dermoscopic characteristics of a hypopigmented and heavily pigmented nodule in a 92-year-old and an 80-year-old woman. Dermoscopy in the former revealed structureless milky-red to white areas, remnants of brown pigmentation at the base and polymorphic vessels, while the latter displayed structureless blue-gray areas with black dots and peripheral lines at the base...

Background: Cumulative data on radiation monotherapy for Merkel cell carcinoma (MCC) is lacking. Objective: We sought to synthesize all available data on treatment outcomes for radiation monotherapy for inoperable stage I-III MCC. Methods: We performed a systematic review of the current literature. Articles published in English in the PubMed database up to July 29, 2016, were evaluated. Results: Eight case reports, 4 case series, and 6 retrospective studies, yielding 68 patients, were included in our analysis...
