Sign of Leser-Trélat associated with adenocarcinoma of the rectum.
ABSTRACT The acute onset and/or rapid increase in size and number of multiple seborrheic keratoses associated with internal malignancy is called sign of Leser-Trélat. Although some authors reject its existence, there are more than 80 well-documented case reports in the literature. Here, we report a 75-year-old man who presented with abrupt appearance of multiple seborrheic keratoses without any suspicious symptom of cancer. The screening for malignant neoplasms let us detect a rectal adenocarcinoma that was in a curative stage. This case-report illustrates a true sign of Leser-Trélat, and proves that these patients must be appropriately investigated for underlying malignancy.

ABSTRACT: Numerous dermatological disorders have been associated with underlining malignancies of the gastrointestinal (GI) tract. Such cutaneous manifestations might have an important diagnostic value if they are the sole expressions of otherwise asymptomatic carcinomas. The recognition of some typical paraneoplastic dermatologic disorders can lead to the prompt diagnosis of the underlying malignancy, timely administration of therapy, and ultimately, better prognosis. In this review we discuss the most common paraneoplastic dermatological syndromes from the perspective of the practicing gastroenterologist. We also outline a comprehensive practical approach for the evaluation for occult malignancy in patients presenting with cutaneous findings potentially associated with GI cancers.World Journal of Gastroenterology 09/2009; 15(35):4372-9. · 2.55 Impact Factor
