Seborrheic warts, usually referred to now as seborrheic keratoses, are rarely discussed, even though they are among the most common benign cutaneous tumors observed in man. According to Freudenthal and Spitzer,1 seborrheic warts were described as early as 1869 by Neumann, who called them "senile" warts.2 Although already widely used, the term "seborrheic warts" was first mentioned in the literature by Barthelèmy3 in 1896. Freudenthal and Spitzer reported that these usually flat and sessile warts could also be mushroom-like and pendulous, and Siemens4 and Pollitzer5 emphasized that they could become very large.
