title: Bilateral Leser-Trélat sign mirroring lung adenocarcinoma with early metastases to the contralateral lung.
abstract: We present a case featuring a unique overlap between the body areas involved by lung adenocarcinoma and the cutaneous paraneoplastic sign of Leser-Trélat. In our patient, the Leser-Trélat sign consisted of explosive multiple seborrheic keratoses in combination with acanthosis nigricans, representing a remarkable geometric skin projection of lung cancer which involved both the upper lobes. Our case suggests a unique interrelation between the paraneoplastic sign of Leser-Trélat and the tumor itself. The recognition of this phenomenon may contribute to an early diagnosis and prompt surgical treatment of occult cancers.
