Article Synopsis
  • A study was conducted to analyze how often dermatologic surgeons face challenges in identifying the locations of skin cancer tumors before surgery.
  • Out of over 17,000 cases, only 0.60% involved uncertain sites, with these cases more common in older, male patients who had biopsies done over a month prior.
  • Surgeons commonly used various methods to confirm tumor locations, achieving success in identifying 82% of these uncertain sites, while some surgeries were delayed, especially for non-facial tumors.

Article Synopsis
  • Inconsistent reporting of outcomes in rosacea clinical trials is hindering accurate data analysis and meta-analyses, highlighting the need for standardized outcome measures.
  • A core outcome set (COS) was developed through systematic literature reviews and a Delphi process, involving feedback from physicians and patients to identify essential outcomes in rosacea trials.
  • The final COS includes 8 key domains, such as skin symptoms and patient satisfaction, which aim to enhance the comparability and relevance of future rosacea research and interventions.

Importance: It has been suggested that Mohs surgery for skin cancer among individuals with limited life expectancy may be associated with needless risk and discomfort, along with increased health care costs.

Objective: To investigate patient- and tumor-specific indications considered by clinicians for treatment of nonmelanoma skin cancer in older individuals.

Design, Setting, And Participants: This multicenter, prospective cohort study was conducted using data from US private practice and academic centers.

Background: There is variation in the outcomes reported in clinical studies of basal cell carcinoma. This can prevent effective meta-analyses from answering important clinical questions.

Objective: To identify a recommended minimum set of core outcomes for basal cell carcinoma clinical trials.

Tuberous sclerosis complex (TSC) is an autosomal-dominant disorder that causes the formation of hamartomatous tumors such as facial angiofibromas (FAs). We present a combination of surgical debulking via shave biopsy, curettage, and electrocautery followed by application of sirolimus ointment 1% to the nose to treat FAs in the setting of TSC. This novel approach achieved an optimal therapeutic response in our patient with minimal recurrence of FAs after 1 year of follow-up.

Importance: Although various treatments have been found in clinical trials to be effective in treating actinic keratosis (AK), researchers often report different outcomes. Heterogeneous outcome reporting precludes the comparison of results across studies and impedes the synthesis of treatment effectiveness in systematic reviews.

Objective: To establish an international core outcome set for all clinical studies on AK treatment using systematic literature review and a Delphi consensus process.

Background: Bleeding is an unavoidable risk of dermatologic surgery. The risk may be higher in patients taking agents that affect hemostasis.

Objective: The aim of this study was to provide an updated review of current anticoagulant and antiplatelet therapy available in the market and their associated risk of bleeding complications in cutaneous surgery.

Background: There are many intraoperative and postoperative techniques to aid hemostasis in dermatologic procedures. An updated understanding is critical for the surgeon.

Objective: To provide an updated review of methods for hemostasis and therapies for postprocedural purpura and ecchymosis applicable to dermatology.

Background: Although treatments to address cosmetic concerns are common, patients' self-reported motives for considering such procedures have not been systematically explored.

Objective: To develop a framework of categories to describe patients' self-reported motivations for undergoing minimally invasive cosmetic procedures.

Methods: Face-to-face, semistructured patient interviews were conducted with adult participants who had undergone or were considering minimally invasive cosmetic dermatologic procedures.

Non-invasive skin-tightening devices can induce thermal denaturation and skin shrinkage via externally applied radiofrequency emissions or high-frequency ultrasound. Therefore, the purpose of this study is to develop and test a method for measurement of skin reduction associated with application of such energy devices. Twenty-five healthy participants with mild to moderate skin laxity of the arms were enrolled.

Cutaneous adnexal malignancies are biologically and pathologically diverse, and associated with a range of clinical outcomes. Given their rarity, the prognosis and optimal treatment of these neoplasms remains unclear. A single institution database from a tertiary care cancer center of patients treated for malignant cutaneous adnexal tumors was retrospectively analyzed.

Background: Compared with other imaging modalities, ultrasound is relatively deeply penetrating and can be used to evaluate deep dermal and subcutaneous structures.

Objective: Image skin thickness of the face and neck using high-frequency diagnostic ultrasound devices.

Materials And Methods: Skin overlying 20 different predesignated face and neck anatomic sites in 32 individuals was imaged using 2 commercially available high-frequency diagnostic ultrasound devices, a dedicated imaging device and a diagnostic device bundled with a therapeutic device.

Background And Objective: Noninvasive fat reduction appears effective, but there are various methods for quantifying changes. The objective of this review is to assess comparative utility measures of subcutaneous fat.

Study Design/materials And Methods: Articles describing noninvasive fat reduction were searched using MEDLINE, EMBASE, CINAHL and Scopus electronic databases on two dates (January 28, 2014 and February 16, 2016).

Background: Squamous cell carcinoma (SCC) is a common skin cancer that poses a risk of metastasis. Clinical investigations into SCC treatment are common, but the outcomes reported are highly variable, omitted, or clinically irrelevant. The outcome heterogeneity and reporting bias of these studies leave clinicians unable to accurately compare studies.

Background: Currently, the isotretinoin (13-cis-retinoic acid) package insert contains language advising the discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. It is common practice to follow this standard because of concerns regarding reports of sporadic adverse events and increased risk of scarring.

Objective: To develop expert consensus regarding the safety of skin procedures, including resurfacing, energy device treatments, and incisional and excisional procedures, in the setting of concurrent or recent isotretinoin use.

Background: Rosacea is a chronic inflammatory disorder affecting millions of individuals worldwide. Diagnosis is based on signs and symptoms with management and treatment aimed to suppress inflammatory lesions, erythema, and telangiectasia. While many clinical trials of rosacea exist, the lack of consensus in outcome reporting across all trials poses a concern.

A six-year-old boy with Pallister-Killian syndrome (PKS) presented to the clinic with extensive lesions on his body (Figure 1). The patient was not born with the lesions but began developing them on the head and neck, extending to his lower extremities, at 2 years of age. These lesions had been evaluated by his primary care physician and were previously treated with desonide and ketoconazole cream with little improvement.
