Exploring Race, Racism, and Structural Racism in Medicine.

Race and racism are rooted in the man-made belief that the color of a person's skin determines a person's hierarchal rank in humanity. Early scientific theories of polygenics and misleading scientific studies were used to promote the concept of the inferiority of people of color and to support and maintain the institution of slavery. These discriminatory practices have filtered into society as structural racism, including the field of medicine. Structural racism has led to health disparities in black and brown communities. Dismantling structural racism requires us all to become change agents at societal and institutional levels.

Erythema migrans and the differential diagnosis of annular erythema.

The diagnosis of Lyme disease (LD) or Lyme borreliosis is often based on the recognition of erythema migrans (EM) because its clinical appearance precedes systemic manifestations of the disease and the antibody response. The clinical basis and variable presentation of EM leave room for diagnostic error and, as a consequence, potential long-term repercussions such as rheumatic, cardiac, ophthalmic, or neurologic complications. Most cases are reported in the Northcentral and Northeastern states. In areas where LD is not endemic, the differential diagnosis of annular erythema may not list EM highly, although all the features of a lesion may fit the typical description of EM. Therefore, a complete understanding of LD and its clinical presentation are key in making a diagnosis, especially in areas with low incidence. We present a hypothetical case report of EM from Oklahoma, a state with low incidence of LD, for the purposes of review of this entity and the differential diagnosis of annular erythema.
