Poikiloderma
Pronunciation: poy-KIL-oh-DER-muh
A chronic skin condition characterised by the triad of hyperpigmentation, hypopigmentation, and telangiectasia, typically resulting from prolonged sun exposure or radiation, most commonly presenting on the neck and décolletage.
Full Definition
Poikiloderma of Civatte is the most frequently encountered form in cosmetic dermatology, presenting as a reticulated, reddish-brown discolouration on the lateral neck and chest sparing sun-protected areas beneath the chin. The term encompasses three simultaneous findings—pigmentary alteration, vascular ectasia, and epidermal atrophy—and editors must understand it as a composite clinical descriptor rather than a diagnosis of a single abnormality. It is commonly treated with IPL or vascular lasers. The word is frequently misspelled as 'poikilodermia'; the correct form ends in '-derma'. Editors should also note that although poikiloderma can be a feature of connective tissue disease, in cosmetic dermatology contexts it almost always refers to photoageing-related changes.
Usage
Usage note: Spell as 'poikiloderma' (not 'poikilodermia'). In cosmetic dermatology documents, qualify with 'of Civatte' if referring to the photodamage-related form.
