Sign of Leser-Trélat Associated with Esophageal Squamous Cell Cancer

Abstract

The sign of Leser-Trélat is a rare paraneoplastic phenomenon marked by accelerated onset of multiple seborrheic keratoses. The occurrence of the sign often points towards underlying visceral malignancies which in a majority are adenocarcinomas of the gastrointestinal tract. We report this case of a 65-year-old man who presented with sign of Leser-Trélat and was diagnosed with poorly differentiated squamous cell cancer of the esophagus. To our knowledge this is only the second such reported association of Leser-Trélat sign with squamous cell cancer of esophagus.
