Dermatology · Skin tumours: xanthelasma
Sample itemA 45-year-old woman has soft, flat, yellowish plaques symmetrically on the inner aspects of both upper eyelids. What is the most appropriate first investigation?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Fasting lipid profile
Xanthelasma palpebrarum is a lipid deposit in the eyelid skin. Many patients have dyslipidaemia, so a lipid profile is done, though a substantial number have normal lipids.
Option by option
A. Serum calcium
Calcium is not a cause of yellow eyelid plaques.
B. Thyroid autoantibodies
Thyroid antibodies are not routinely linked to xanthelasma.
C. Skin biopsy
A biopsy is rarely needed because the appearance is characteristic.
D. Fasting lipid profile (correct)
Correct. A lipid profile is the first step in evaluating xanthelasma.
