Dermatoscopic finding of white circles in an invasive pigmented melanoma

Australas J Dermatol. 2023 Jan 30. doi: 10.1111/ajd.13985. Online ahead of print.


Dermatoscopic white circles, seen with both non-polarized and polarized dermatoscopy, are a known clue to actinic keratosis in a flat lesion and invasive squamous cell carcinoma in a raised lesion. We have not discovered a previous published example of this clue in a melanoma. We present a case report of a 70-year-old Australian male with a pigmented superficial spreading melanoma on the face, Breslow thickness 1 mm, with dermatoscopic white circles displayed with both polarized and non-polarized dermatoscopy, and with dermatopathological correlation.

Keywords: SCC; actinc keratosis; dermatoscopy; dermoscopy; melanoma; white circles.
