Multiple cutaneous leiomyomas, also known as Pilar leiomyomas,[2] arise from the arrectores pilorum muscles, and are made up of a poorly circumscribed proliferation of haphazardly arranged smooth muscle fibers located in the dermis that appear to infiltrate the surrounding tissue and may extend into the subcutis.[2]

Sometimes associated with uterine leiomyomas (a combination known as multiple cutaneous and uterine leiomyomatosis, MCUL), these lesions may also be a manifestation of the hereditary leiomyomatosis and renal cell cancer syndrome.
