Topically applied cosmetics and medicaments containing botanical extracts are commonly used. Despite popular beliefs of their benignancy, some botanicals have been implicated in causing allergic contact dermatitis in susceptible patients. The offending allergen may be the botanical extract itself or another ingredient such as a fragrance, preservative, dye, or sunscreen found in the product. Specific botanicals implicated in causing cosmetic contact dermatitis include Compositae family plants, tea tree oil, peppermint, lavender, lichens, henna, and others.

The incidence of melanoma is on the rise, and early detection of disease is imperative to
reduce mortality. Dermatologists are key players in the early detection of melanoma;
however, some clinicians rely on their clinical examination without any additional diagnostic
tools to make this important diagnosis. Certain patients, such as atypical nevus patients,
have more complicated mole examinations, making the diagnosis of melanoma difficult,
whereas some melanomas, such as amelanotic melanomas, can be diagnostically challenging.
The goal of the clinician is to detect melanoma with the highest accuracy, while
avoiding unnecessary biopsies. Using diagnostic melanoma tools as an adjunct to the
clinical examination, dermatologists have the opportunity to increase both their sensitivity
and specificity for melanoma detection. This article will review current imaging technologies
and those in development for pigmented lesions, updating the clinician on basic
principals of such modalities and clinical use of such technologies in practice.

Cutaneous changes are a common feature of chronic venous insufficiency and include venous eczema and lipodermatosclerosis. This review will address the presumed pathophysiology of these conditions, their clinical findings, and important management strategies.

The detection of cutaneous melanoma still largely relies on clinical suspicion, skin biopsy,
and histopathologic evaluation. New technologies are being evaluated to bypass the skin
biopsy in the detection of melanoma. The quest for reliable biomarkers, with respect to
subclinical detection, prognosis, and predicting treatment response, is longstanding and
ongoing. New therapies have been developed for metastatic disease, including targeted
small molecule inhibitors as well as immune modulators.
