Mammary Paget disease is the intraepidermal adenocarcinoma of the nipple area which is characterized usually by a well-demarcated eczematous plaque. Reflectance confocal microscopy (RCM), is an in vivo noninvasive diagnostic tool with a high-resolution imaging of the skin, almost comparable to conventional histology. RCM findings of Paget disease are limited in the literature. Most of the reported cases are the extramammary type. In this report, we aimed to evaluate the RCM findings of a non-pigmented mammary Paget disease in a 65 year-old woman...

Neurofibromatosis type 1 (NF1) is a genetic disorder commonly associated with an increased risk for development of malignancy, including skin cancers. Herein we describe a case of invasive melanoma occurring in a patient with NF1 and discuss the association between these two diseases, highlighting the importance of comparative clinical and dermoscopic approaches in this category of patients in which the detection of melanoma can be difficult because of the presence of multiple skin tumors.

Introduction: Family physicians (FPs) play a critical role in the early detection of skin cancers. Dermoscopy can improve diagnostic accuracy but its use by FPs in the United States (US) remains understudied. Objectives: To examine dermoscopy use, factors associated with ever having used (Model 1) and currently using the dermascope (Model 2), and barriers. Methods: We recruited 705 practicing FPs in-person at conferences and on-line to complete an anonymous, 46 item survey measuring: demographic factors, physician and practice characteristics; confidence in differentiating skin lesions; knowledge and use of dermoscopy; intentions to use; and barriers to use...

We present an unusual onset of cutaneous lichen planus (LP) in a middle-aged patient. The initial presentation as solitary, indolent pink lesion required further investigations to rule out malignancy, especially amelanotic melanoma. Dermoscopy and reflectance confocal microscopy findings were found to be helpful in our case in addressing the correct diagnosis.

Distinguishing between benign and malignant neoplasms of the skin is a daily challenge to dermatologists. With the use of a dermatoscope and other imaging devices, the diagnosis is often more precise. The confocal microscope is a device that uses a near-infrared laser to perform noninvasive imaging of the skin. The benefit is that the images immediately provide additional, cellular-level information that can assist in diagnosis. However, lesions may share overlapping characteristics on confocal microscopy, and hence, benign lesions can still display confocal features concerning for a cancerous process, justifying a biopsy...

Dietary change may play a role in the therapy of rosacea. Certain foods and beverages may act as "triggers" for rosacea exacerbations. These may be divided into heat-related, alcohol-related, capsaicin-related, and cinnamaldehyde-related. One potential pathogenic mechanism may be via the activation of transient receptor potential cation channels, which result in neurogenic vasodilatation. Further research is needed on the role of the gut skin connection in rosacea. Epidemiologic studies suggest that patients with rosacea have a higher prevalence of gastrointestinal disease, and one study reported improvement in rosacea following successful treatment of small intestinal bacterial overgrowth...

Background: Certain studies suggest that percutaneous absorption of topical steroids may cause suppression of hypothalamic-pituitary-adrenal axis (HPAA) in atopic dermatitis (AD) patients. This study aimed to investigate the basal serum cortisol, adrenocorticotropic hormone (ACTH), and IgE levels in patients with AD and their correlation with the disease severity. Methods: Levels of basal serum cortisol, ACTH, and IgE were assessed by ELISA in 31 patients with AD and 31 controls...

Chromoblastomycosis is a chronic cutaneous fungal infection commonly caused by Fonsacea and Cladophialophora spp. Dermoscopy is a non-invasive, real-time diagnostic tool for rapid bedside diagnosis of various inflammatory and non-inflammatory disorders and can be an excellent modality for evaluation of cutaneous mycosis, for which it shows characteristic brown dots, crust, scales and yellow orange structures.

Background: Spermidine has been shown both in vitro and in mice models to have an anagen-prolonging effect on hair follicles (HFs). Objectives: To evaluate the effects of a spermidine-based nutritional supplement on the anagen phase of HFs in healthy human subjects in a randomized, double-blind, placebo-controlled trial. Methods: One hundred healthy males and females were randomized to receive a tablet containing a spermidine-based nutritional supplement or a placebo once daily for 90 days...

The majority of oral pigmentations are benign lesions such as nevi, melanotic macules, melanoacanthomas or amalgam tattoos. Conversely, mucosal melanomas are rare but often lethal; therefore, excluding oral melanomas in this setting is crucial. Reflectance confocal microscopy is a non-invasive, in vivo imaging system with cellular resolution that has been used to distinguish benign from malignant pigmented lesions in the skin, and more recently in the mucosa. However, lesions located posteriorly in the oral cavity are difficult to assess visually and difficult to biopsy due to their location...

White rosettes are shiny white structures seen as four oval-shaped points that come together in the center. They resemble four-leaf clover [1]. Earlier it was thought they were specific for actinic keratosis and squamous cell carcinoma, but they are noted in many other conditions [2]. With polarized light dermoscopy, it is evident that rosettes are seen only and they are due to the optical effect between polarized light and follicular structures [3]. Here, authors describe cases of discoid lupus erythematosus (DLE) demonstrating rosettes under polarized dermoscopy...

Background: We previously described a new variant of endemic pemphigus foliaceus in El Bagre, Colombia, South America (El Bagre-EPF, or pemphigus Abreu-Manu). El Bagre-EPF differs from other types of EPF clinically, epidemiologically, immunologically and in its target antigens. We reported the presence of patient autoantibodies colocalizing with armadillo repeat gene deleted in velo-cardio-facial syndrome (ARVCF), a catenin cell junction protein colocalizing with El Bagre-EPF autoantibodies in the heart and within pilosebaceous units along their neurovascular supply routes...

Diffuse neonatal hemangiomatosis is a rare condition with a very high mortality rate if left untreated. We report a neonate having around 490 cutaneous and multiple diffuse liver hemangiomas presenting as congestive heart failure. Prompt treatment was instituted with decongestive drugs and prednisolone for anticipated life threatening complications due to hepatic hemangiomas. Propranolol was added later as it is known to precipitate congestive failure and also to avoid long-term complications of steroids. The child responded well...

Syphilitic alopecia (SA) is considered an uncommon manifestation of secondary syphilis. SA can present in a diffuse form, resembling telogen effluvium, or in a moth-eaten form that mimics a variety of conditions (i.e., alopecia areata, trichotillomania, lichen planus pilaris or tinea capitis). When the two forms coexist, we observe a mixed pattern. Essential SA manifests without evidence of mucocutaneous syphilis manifestations and its diagnosis is often delayed. To date, trichoscopic description of SA forms are based on very few cases (i...

Grover's disease is a benign condition of unknown origin characterized clinically by an erythematous papulovesicular eruption and histopathologically by intraepidermal clefting and four different patterns of acantholysis: Darier-like, pemphigus-like, spongiotic, and Hailey-Hailey-like. A case of a 54-year-old female affected by Grover's disease and showing a Darier-like histopathological pattern is described. Polarized light dermoscopy (PLD) revealed the presence of polygonal, star-like shaped yellowish/brownish areas of various sizes surrounded by a thin whitish halo...

The diagnosis of a single small pink papule poses a real challenge to the clinician, as the differential diagnosis of such lesions includes benign entities such as a neurofibroma or hemangioma, as well as aggressive and potentially fatal skin malignancies such as amelanotic melanoma or Merkel cell carcinoma (MCC). The absence of a benign vascular pattern and the presence of atypical vascular features under dermoscopy direct the clinician to proceed to histologic evaluation in order to rule out a malignant process in such lesions...
