Plant dermatitis is a common pathology that plagues those who work and recreate in the North American outdoors. The most common plant family to cause dermatitis is the Toxicodendron genus, which includes the plants known by the common names of poison ivy, poison oak, and poison sumac. While mortality is usually quite low for this pathology, the incidence and prevalence of the disease leads to substantial healthcare burden and financial implications across the population. The mainstays of treatment have focused on prevention, corticosteroids, and antihistamines.

Deserts are defined by their arid nature, characterized by little rainfall, and often featuring vast stretches of sandy terrain with sparse vegetation. The resulting variations in temperature, humidity, and topography predispose patients to medical conditions that practitioners in both rural and urban deserts must recognize and manage. This article will equip medical practitioners with the essential knowledge and tools to navigate these complexities, including a description of specific environmental considerations and challenges encountered while providing care in these desert locations, common conditions associated with extreme heat and solar radiation, and animal encounters.
