Benign Dermoscopic Parallel Ridge Pattern Variants

Does it look like melanoma? A pilot study of the effect of sunless tanning on dermoscopy of pigmented skin lesions

“…11,12 The main finding of this study was that the use of DHA can lead to temporary changes in dermoscopic features in PSLs. 11,12 The main finding of this study was that the use of DHA can lead to temporary changes in dermoscopic features in PSLs.…”

“…Previous reports have shown that DHA can affect dermoscopy and even simulate MM. 11,12 The main finding of this study was that the use of DHA can lead to temporary changes in dermoscopic features in PSLs. For facial SL ⁄ISK there may be a risk that the use of DHA can affect the dermoscopic diagnosis and clinical management, because FP was seen after application of DHA.…”

“…11,12 To address this issue a pilot study was performed, using a product containing DHA and investigating whether its use could lead to changes in the dermoscopic features of facial SL ⁄ISK or naevi on the body. An earlier case report has shown that new dermoscopic features can appear after the use of DHA, and more recently it was shown that DHA can cause pigmentation that simulates acral MM.…”

Parallel Ridge Pattern Due to Cryotherapy Treatment

“…For example, patients undergoing systemic psoriasis treatments often face issues of access (eg, treatment expense, delays in obtaining insurance approvals to continue treatment or lack of insurance approval to increase the dose of treatment owing to suboptimal response, and difficulty in traveling to offices that provide psoriasis treatment) and tachyphylaxis, and often patients express safety concerns that result in treatment discontinuation. 3 In addition, prior treatment experience, which may inform response rates, may not be reflected in clinical trials (eg, the ACCEPT 4 …”
