Clear cell papulosis (CCP) causes small white papules most typically on the abdomen of a child.


The child has multiple white papules, round or oval, with a smooth, flat surface, 2-10 mm in diameter. The number may range from 5 to more than 100. The lower abdomen is a favored site, but the chest, shoulder and inguinal area are also affected.

Histology shows a proliferation of clear cells in the basal epidermis, larger than adjacent keratinocytes.


It is assumed that this disease spontaneously disappears before adulthood. In one long term study with a median follow-up duration of 11.5 years, regression of skin lesions was observed in 85.7% of patients [JAAD August 2010 Volume 63, Issue 2, Pages 266–273].
