Medical Must-See: A skin-deep mystery that just needed UV light

Saudi Arabian doctors have shed light on the case of a 43-year-old with chronic atopic dermatitis who developed a new rash on her upper extremities, including her palms.
The rash did not respond to medium-potency topical steroids and, over six months, spread to her lower extremities, including her soles.
The patient had palmoplantar keratoderma and well-demarcated, fine and scaly erythematous patches, with areas of spared skin and nothing on her trunk.
She was on salbutamol and periodic IV antibiotics for bronchiectasis and had a goitre that was under observation, her doctors wrote in Cureus.
