The sign of Leser-Trélat may be more precisely defined as the abrupt appearance of multiple seborrheic keratoses caused by an associated cancer and the rapid increase in their size and number. This definition is parallel to that of malignant acanthosis nigricans; both conditions are obligate paraneoplastic syndromes.
