Background: Solid organ transplant recipients are at high risk for developing skin malignancies due to prolonged immunosuppression. The field of transplant dermatology (TD) has experienced a surge in research and clinical advancements, yet there is no quantitative evaluation estimating the impact of TD literature.
Objective: Identify and characterize the most frequently cited TD articles.
Importance: Nicotinamide metabolites have recently been implicated in increased risk of major cardiovascular events (MACE). Supportive data about clinical risk of MACE for nicotinamide users is lacking.
Objective: To determine whether nicotinamide use results in an increase of MACE.
Background: Residual tumor is not always clinically apparent following biopsy of cutaneous carcinomas, which may prompt patients to question the need for definitive treatment.
Objective: We investigated the percentage of cases in which residual tumor was histologically present at the time of Mohs micrographic surgery (MMS) for basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) and investigated factors associated with residual tumor.
Methods: We examined 483 MMS cases performed for biopsy-proven BCC (n = 287) and SCC (n = 196) between October 2022 and April 2023.
Importance: Cutaneous squamous cell carcinoma (CSCC) is the second most common malignant disease in the US. Although it typically carries a good prognosis, a subset of CSCCs are highly aggressive, carrying regional and distant metastatic potential. Due to its high incidence, this aggressive subset is responsible for considerable mortality, with an overall annual mortality estimated to equal or even surpass melanoma.

We conducted a prospective clinical trial testing nivolumab (NIVO) + tacrolimus (TACRO) + prednisone (PRED) ± ipilimumab (IPI) in KTR with advanced cutaneous cancers.
Methods: Adult KTR with advanced melanoma or basal, cutaneous squamous, or Merkel cell carcinomas were eligible.

The NCCN Guidelines for Merkel Cell Carcinoma (MCC) provide recommendations for diagnostic workup, clinical stage, and treatment options for patients. The panel meets annually to discuss updates to the guidelines based on comments from expert review from panel members, institutional review, as well as submissions from within NCCN and external organizations. These NCCN Guidelines Insights focus on the introduction of a new page for locally advanced disease in the setting of clinical node negative status, entitled "Clinical N0 Disease, Locally Advanced MCC.

In addition to an abundance in number, the morbidity and mortality of these tumors in this patient population exceeds that of immune competent individuals. Here, we used whole exome and bulk RNA sequencing to analyze mutation profiles between tumors arising in immunocompetent and immunosuppressed patients.

Objective: This study investigated socioeconomic and demographic factors associated with delays or failure to complete dermatology referrals and potential impact on surgical outcomes.
Basal cell carcinoma (BCC) is the most common form of skin cancer in the United States. Due to the high frequency, BCC occurrences are not typically recorded, and annual rates of incidence can only be estimated. Current estimated rates are 2 million Americans affected annually, and this continues to rise.

Objective: We investigated the factors associated with patient satisfaction in MMS for nonmelanoma skin cancer and how patient satisfaction changes in the postoperative period.
Methods: In this prospective cohort study including 100 patients, patient satisfaction surveys were administered at the time of surgery and at 3 months postsurgery.
Unlabelled: We studied the feasibility of transplant-clinic staff routinely providing primary prevention advice to lung transplant recipients at high risk of skin cancer.
Methods: Patients enrolled by a transplant-clinic study nurse completed baseline questionnaires and received sun-safety brochures. For the 12-mo intervention, transplant physicians were alerted to provide standard sun-protection advice (use of hat, long sleeves, and sunscreen outdoors) by sun-advice prompt cards attached to participants' medical charts at each clinic visit.
Background: Patients undergoing dermatologic surgery report higher anxiety levels than those undergoing nonsurgical treatments. However, little is known about the association between patient-perceived delays in skin cancer surgery and patient-reported anxiety.
Objective: To examine the relationship between patient-perceived delays in surgery and patient-reported anxiety.
The impact of time to treatment (TTT) on the surgical management of keratinocyte carcinoma, specifically the complexity of Mohs micrographic surgery (MMS), is incompletely understood. We performed a retrospective chart review of patients undergoing MMS for keratinocyte carcinoma between July 1, 2019 and February 28, 2021 to examine associations between TTT and surgical characteristics. The median TTT for the 1571 patients treated with MMS during the study period was 42 days (interquartile range 28-61 days).

Many patients subsequently develop multiple CSCC following a first CSCC, and the risk of metastasis and death is significantly increased compared to the general population. Post-transplant CSCC represents a disease at the interface of dermatology and transplant medicine.

However, the molecular underpinnings of these tumors are still poorly understood. Dissecting human cSCC pathogenesis amplifies the exigence for preclinical models that mimic invasion and nodal spread.

View Article and Find Full Text PDFBackground: Current staging systems for cutaneous squamous cell carcinoma (cSCC) have limited positive predictive value for identifying patients who will experience metastasis.
Objective: To develop and validate a gene expression profile (GEP) test for predicting risk for metastasis in localized, high-risk cSCC with the goal of improving risk-directed patient management.
Methods: Archival formalin-fixed paraffin-embedded primary cSCC tissue and clinicopathologic data (n = 586) were collected from 23 independent centers in a prospectively designed study.
