The Sign of Leser–Trélat as a Possible Indicator of Prostate Adenocarcinoma: A Case Report

Backgrounds The sign of Leser–Trélat (SLT) is defined by the abrupt onset of multiple pruritic or nonpruritic seborrhoeic keratoses (SKs) over a short interval, predominantly affecting the back, and is most frequently associated with internal malignant neoplasia, particularly gastric and colorectal adenocarcinoma. Case Presentation We report a rare case of a 65‐year‐old male with SLT in association with prostate adenocarcinoma. Conclusions This report underscores the importance of including prostate assessment in the diagnostic work‐up of men with rapidly evolving, multiple, and progressive SKs.
