This is a report on a 38-year-old female, suffering from over 100 soli
d papules arising on her legs, arms and trunk during the past 10 years
, The histology shows the typical feature of clear-cell acanthoma (CCA
). Extensive investigations did not reveal any extracutaneous abnormal
ities, This case is exceptional because of the high number of hamartom
atous CCA which exceeds the maximal number of about 20 seen in multipl
e CCA so far and therefore is referred to as eruptive hamartomatous CC
