Painted Butterfly Rash: The Red Queen Effect in a Rembrandt Portrait

The document explores the intersection of art and medicine by examining a Rembrandt portrait that may depict signs of systemic lupus erythematosus (SLE), specifically a malar rash and frontal alopecia. The malar rash, a hallmark of SLE, appears as a butterfly-shaped erythema on the face, often triggered by sun exposure. The analysis suggests that the woman in the painting exhibits these features, highlighting the potential of iconodiagnosis—using art to identify medical conditions. This approach not only aids in medical education by enhancing observational skills but also provides insights into the historical perception of diseases. The study underscores the value of integrating artistic and clinical observations to enrich understanding of medical conditions.
