Poikiloderma vasculare atrophicans

[7] PVA causes areas of affected skin to appear speckled red and inflamed, yellowish and/or brown, gray or grayish-black, with scaling and a thinness that may be described as "cigarette paper".

[5] PVA can be characterized by speckled, combined hyper- and hypopigmentation in the plaques or patches of affected skin.

Telangiectasia, the visible "vascular" element of PVA, is the dilation of small blood vessels near the skin surface.

[5] Atrophy of the skin gives it a thin, dry and wrinkled appearance, which in PVA-affected individuals has been described as "cigarette paper".

[5][9] PVA usually has an underlying cause, attributed to existing skin diseases and disorders associated with a cutaneous lymphoma or inflammation.

[5] Brocq chose the term "parapsoriasis" to illustrate that the dermatoses placed in this group had or would have commonalities with psoriasiasis, including appearance and chronicity (lifelong or indefinite duration).

[5] Additionally, it may be considered a precursor or variant of the lymphomatous skin disorder mycosis fungoides, which is also associated with large plaque parapsoriasis.

[5] When the condition of the skin encompassed by these plaques worsens and becomes atrophic, it is typically considered retiform parapsoriasis.

[5] Usage of the entire term "poikiloderma vasculare atrophicans" may also be reserved to indicate it as the primary condition affecting the skin in cases where the disorder associated with it is secondary.
