Direct-to-patient mobile teledermoscopy is a feasible and useful adjunct to smartphone imaging for monitoring patient-identified lesions of concern, achieving comparable diagnostic and management accuracy as in-office dermatology.

Background: Teledermoscopy improves teledermatology clinical outcomes, but the practical impact of this and other teleconsultation variables on patient management are unclear. We assessed the impact of these variables, including dermoscopy, on face-to-face (F2F) referrals to optimize effort by imagers and dermatologists.

Methods: Using retrospective chart review, we retrieved demographic, consultation, and outcome variables from 377 interfacility teleconsultations sent to San Francisco Veterans Affairs Health Care System (SFVAHCS) between September 2018 to March 2019 from another VA facility and its satellite clinics.

Teledermatology has emerged as a promising method of continuing dermatologic care during the coronavirus 2019 (COVID-19) pandemic, including in the Department of Veterans Affairs (VA). Analysis of the utilization and impact of teledermatology within the San Francisco Veterans Affairs Health Care System (SFVAHCS) may elucidate the ways that teledermatology programs can continue to be optimized. We conducted a retrospective analysis of live interactive encounters, Veterans Affairs Video Connect (VVC), store-and-forward telehealth (SFT), and face-to-face (FTF) consultations, performed within the SFVAHCS from March 2020 to December 2020.

Cutaneous endometriosis is a disorder that primarily affects women of reproductive age. The disorder is most commonly associated with cyclical pain during menses, but it can be difficult to diagnose in the absence of these symptoms and requires biopsy testing for a definitive diagnosis. We report on a case of a 41-year-old patient undergoing hormonal therapy for infertility who presented with a painful firm subcutaneous nodule in the umbilicus.

Skin cancer is the most common malignancy affecting solid organ transplant recipients (SOTR), and SOTR experience increased skin cancer-associated morbidity and mortality. There are no formal multidisciplinary guidelines for skin cancer screening after transplant, and current practices are widely variable. We conducted three rounds of Delphi method surveys with a panel of 84 U.

Importance: Risk factors for the development of skin cancer after solid-organ transplant can inform clinical care, but data on these risk factors are limited.

Objective: To study the association between HLA antigen mismatch and skin cancer incidence after solid-organ transplant.

Design, Setting, And Participants: This retrospective cohort study is a secondary analysis of the multicenter Transplant Skin Cancer Network study of 10 649 adults who underwent a primary solid-organ transplant between January 1, 2003, and December 31, 2003, or between January 1, 2008, and December 31, 2008.
