    TLDR SCAD can indicate ANA-negative lupus, especially in women with unusual symptoms.
    This case report describes the first known instance of spontaneous coronary artery dissection (SCAD) as the primary presentation of ANA-negative systemic lupus erythematosus (SLE) in a 55-year-old woman. Despite negative ANA screening, the patient met the criteria for SLE diagnosis due to symptoms like hair loss, oral ulcers, and joint pain, along with positive anti-double stranded DNA antibodies. The case underscores the need to consider SCAD in myocardial infarction diagnoses, especially in women with atypical risk factors or rheumatological conditions, and suggests a low threshold for rheumatological evaluation in SCAD patients.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
