Hypertrophic lichen planus (HLP), also known as LP verrucosus, is a form of lichen planus where lesions are lichenified and thicker than the typical flat, purple, polygonal lesions found in lichen planus. Lesions may have a covering of scale. HLP commonly affects middle aged men and women. Lesions are most commonly located bilaterally on the shins and ankles and can be painful or pruritic.

Angiosarcomas are uncommon, high-grade malignant tumors of endothelial cell origin that can arise via the lymphatics or vasculature. They typically occur spontaneously; however, there have been cases reported of benign vascular transformation. These tumors are more commonly found in elderly men on the head and neck in sun-damaged skin. Radiation-induced angiosarcoma occurs in an estimated 0.05%-0.3% of patients with breast cancer who underwent surgery and radiation therapy.

Erythema chronicum migrans (ECM) is the classical dermatologic manifestation of Lyme disease, a condition caused by Borrelia burgdorferi, a bacterial spirochete. Lyme disease is the most commonly transmitted tick-borne illness in the United States. This infection is typically transmitted through a bite by the Ixodes tick commonly found in the Midwest, Northeast, and mid-Atlantic regions; however, the geographical distribution continues to expand over time in the United States.
