The answer and the reasoning

D. Spider naevus (naevus araneus)

Spider naevi have a central feeding arteriole with radiating telangiectasia and blanch with pressure, with release showing refilling from the centre. They are common in pregnancy and liver disease due to raised oestrogen. Pregnancy lesions often regress after delivery.

Option by option

    Petechiae do not blanch.

  • B. Venous lake

    Venous lakes are blue compressible papules on the lips and ears.

  • C. Cherry angioma

    Cherry angiomas are discrete red papules without radiating vessels.

  • D. Spider naevus (naevus araneus) (correct)

    Correct. A central arteriole with radiating vessels is a spider naevus.
