Pruritus as a Symptom in Hyperthyroidism

    July 1968 in “ JAMA ”
    Benjamin Rothfeld
    TLDR Itching can be an early sign of hyperthyroidism.
    A 43-year-old woman experienced severe pruritus and significant hair loss, which led to the discovery of hyperthyroidism, indicated by an elevated serum protein bound iodine (PBI) level of 10.7 μg/100 cc. Additional symptoms included diminished heat tolerance, poor appetite, and weight loss. This case highlighted that pruritus, without visible skin disease, could be an initial symptom of hyperthyroidism.

      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.
