A case of multiple pilomatricomas erupting within a span of four years occurred in a young girl. This is apparently the first reported case of five histologically confirmed pilomatricomas appearing in the same individual. The incidence of multiple lesions is reviewed and the eruptive manner in which these lesions developed is emphasized. A new, modified mammographic technique proved more sensitive than the routine soft tissue roentgenography in the detection of fine tumor calcification.
