Seborrheic keratoses of florid eruption

Abstract

We report the case of a 79-year-old Caucasian man, who developed numerous pruritic seborrheic keratoses on his chest and back within one year. An underlying malignant disease was suspected. Upper and lower endoscopies were performed and the patient was diagnosed with adenocarcinoma of the ascending colon. We discuss the clinical significance of his cutaneous symptoms/signs, and review the medical literature on the paraneoplastic sign of Leser-Trélat. © 2013 S. Karger AG, Basel.
