D) Angioma serpiginosum
PPD can at times resemble angioma serpiginosum, which generally presents as a solitary lesion characterized by vascular ectasia, often seen in young females. The lesion is a copper-colored annular or serpiginous patch with multiple angiomatous papules. The solitary and unilateral nature and larger angiomatous papules, rather than minute petechiae, help to distinguish angioma serpiginosum from PPD.
