Paradoxical effect of epinephrine on lesion redness and vascularity.

Introduction: Epinephrine is commonly used in combination with local anesthetic (lidocaine/epinephrine) due to its beneficial vasoconstrictive properties. Typically, pallor is appreciated after injection as a sign of effect; however, we observed that some cutaneous malignancies paradoxically revealed increased redness and vascularity after injection of lidocaine/epinephrine. In this study, we investigate this phenomenon among a series of biopsied lesions to identify characteristics of lesions associated with increased redness and/or vascularity.

Dermoscopy of Linear Basal Cell Carcinomas, a Potential Mimicker of Linear Lesions: a Descriptive Case-series.

Introduction: Among the various widely recognized basal cell carcinoma (BCC) clinical patterns, linear basal cell carcinoma (LBCC) is an uncommon morphologic variant of BCC.

Objectives: Describe the clinical and dermoscopic characteristics of LBCC.

Methods: Retrospective study including LBCC cases from 5 dermatology centers in North and South America.

Congenital cutaneous candidiasis in a full-term neonate.

We present a case of a full-term neonate born with respiratory distress and a widespread erythematous rash, who was found to have congenital cutaneous candidiasis (CCC). The significance of this report is to contribute to the pre-existing literature on the rarity of CCC, but also to share a case of a patient who was successfully treated conservatively with topical antifungal agents only.

Optical coherence tomography.

During the past decade, noninvasive imaging has emerged as a valuable tool in clinical dermatology and dermatologic research. Optical coherence tomography (OCT) is one such type of noninvasive imaging. OCT uses the principle of interferometry to produce real-time images.

Bilateral diffuse uveal melanocytic proliferation with multifocal diffuse integumentary melanocytic proliferation paraneoplastic syndrome: A case report.

Bilateral diffuse uveal melanocytic proliferation (B-DUMP) is a rare paraneoplastic syndrome typically presenting with bilateral visual loss. B-DUMP is associated with extraocular systemic malignancies with the most common being lung cancer in males and uro-gynaecological cancer in females (mainly ovarian cancer). Cutaneous and/or mucosal involvement in patients with B-DUMP has been reported but it is not well characterised.

Combining Reflective Confocal Microscopy and Dynamic Optical Coherence Tomography to Diagnose Melanoacanthoma: Case Report.

Few reported cases discuss distinguishing between melanoma and melanoacanthoma, a seborrheic keratosis (SK) variant, using noninvasive imaging devices. We present a case of a 38-year-old man with Fitzpatrick skin type IV with an asymmetric black papule showing clinical and dermoscopic features of both melanoma and SK. Reflectance confocal microscopy (RCM) and dynamic optical coherence tomography (d-OCT) were used for further evaluation.

Clinical and dermoscopic features of Fibroepithelioma of Pinkus: case series with an emphasis on hypopigmented to pink lines intersecting at acute angles.

Fibroepithelioma of Pinkus (FEP) is a subtype of basal cell carcinoma (BCC) that can clinically resemble intradermal nevi (IDN) and fibromas. We performed a retrospective review of consecutively biopsied lesions confirmed to be FEP on histopathology diagnosed from January 1, 2008 to April 8, 2019. Clinical (n = 48), contact non-polarized dermoscopy (NPD) (n = 44), and contact polarized dermoscopy (PD) (n = 22) images from 36 patients were reviewed.

Association of Multiple Aggregated Yellow-White Globules With Nonpigmented Basal Cell Carcinoma.

Importance: Basal cell carcinoma (BCC) is the most common skin cancer. Dermoscopic imaging has improved diagnostic accuracy; however, diagnosis of nonpigmented BCC remains limited to arborizing vessels, ulceration, and shiny white structures.

Objective: To assess multiple aggregated yellow-white (MAY) globules as a diagnostic feature for BCC.

Emerging noninvasive treatments of nonmelanoma skin cancers.

Nonmelanoma skin cancer (NMSC) is the most common malignancy worldwide, and the incidence continues to increase. Originally, treatment options for NMSCs largely relied on destructive and surgical methods. Basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) commonly are treated with cryosurgery, electrodesiccation and curettage, or more definitive surgical options.

Dermoscopy: A Review of the Structures That Facilitate Melanoma Detection.

Melanoma is currently the fifth most common cancer in the United States, resulting in more than 9000 deaths each year. Despite numerous improvements in the management of advanced melanoma, the cornerstone to ensuring a cure remains early detection. Both patient and physician awareness regarding the signs and symptoms of early melanoma remain paramount.

Assessment of the Safety Risk of Dermatoscope Magnets in Patients With Cardiovascular Implanted Electronic Devices.

Importance: Cardiovascular implanted electronic devices (CIEDs) are susceptible to electromagnetic interference. Dermatologists regularly use devices containing magnets, including dermatoscopes and their attachments, which could pose a hazard to patients with CIEDs.

Objective: To investigate the safety risk of magnets in dermatoscopes to patients with CIEDs.
