Approximately 30% of Canadians will be members of a visible minority by 2031. When dermatology became an independent medical discipline in the late 18th and early 19th centuries, most residents of Canada and the United States were of Northern European descent. Morphology and descriptions of dermatoses are based on patients with light skin. Skin of colour dermatology refers to a unique field in dermatology dedicated to the diagnosis and management of disorders that are more prevalent in patients with moderately to richly pigmented skin...

Importance: Perineural invasion (PNI) in cutaneous squamous cell carcinoma (CSCC) has been associated with an increased risk of poor outcomes. Patients with PNI may present with clinical symptoms and/or radiologic evidence of PNI (clinical PNI [CPNI]), yet most patients are asymptomatic and PNI is often found on histologic examination (incidental PNI [IPNI]). Evidence-based estimates of the risks of disease-related outcomes comparing IPNI and CPNI are limited in the dermatology literature...

PURPOSE: The Dermatology Life Quality Index (DLQI) and the European Quality of Life-5 Dimension (EQ-5D) are separate measures that may be used to gather health-related quality of life (HRQoL) information from patients. The EQ-5D is a generic measure from which health utility estimates can be derived, whereas the DLQI is a specialty-specific measure to assess HRQoL. To reduce the burden of multiple measures being administered and to enable a more disease-specific calculation of health utility estimates, we explored an established mathematical technique known as ordinal logistic regression (OLR) to develop an appropriate model to map DLQI data to EQ-5D-based health utility estimates...

Skin damage induced by UVR is an escalating problem in dermatology, and increasing incidence of skin cancer, especially for non-melanoma skin cancer, has been reported worldwide. UVR from sun exposure and the production of reactive oxygen species (ROS) is known to be a pivotal factor in the aetiology of skin cancer. The pineal hormone melatonin is recognized as the most potent endogenous antioxidant. Melatonin conducts its antioxidant effects acting directly as a radical scavenger and indirectly by up regulation of antioxidant enzymes...

Long-term utilization of immunosuppression in organ transplant recipients (OTRs) leads to decreased immune-mediated tumor surveillance and development of malignant tumors. A delicate balance needs to be maintained in the intensity of immunosuppression to keep the risk of malignancy low without jeopardizing life-saving graft function. OTRs are prone to developing skin cancers that exhibit unique epidemiologic, pathophysiologic, and prognostic characteristics. In this review, we discuss the most commonly reported skin cancers in OTRs: squamous cell carcinoma (SCC), basal cell carcinoma (BCC), Kaposi sarcoma, Merkel cell carcinoma, and malignant melanoma (MM)...

Actinic keratosis (AK) is a common dermatologic condition in which hyperplastic epidermal lesions develop in response to excessive and chronic exposure to ultraviolet (UV) radiation. If left untreated, AK can progress to squamous cell carcinomas of the skin. Incidence is rising worldwide as a result of the progressive aging of populations and an increase in lifetime cumulative exposure to UV radiation. Currently, various treatment options exist, which range from topical medications to light-based therapies and procedural modalities...
