Background and Aims: Reduction mammaplasty is a popular procedure in plastic surgery. Occasionally, occult invasive breast carcinoma or findings demonstrating increased risk of breast cancer occur in reduction mammaplasty specimens. The incidences have been studied elsewhere, but in Finland, the data on this subject are lacking. Our aim was to analyze the incidence of occult invasive and in situ carcinoma and benign breast disease causing increased risk of breast cancer in reduction mammaplasty specimens. We also analyzed preoperative mammograms and ultrasound images and compared findings with reduction mammaplasty specimens. Material and Methods: We performed a retrospective study of 100 women who underwent reduction mammaplasty during 1 January 2007 to 30 April 2009 in Jorvi Hospital day-surgery unit. Demographic data, findings in preoperative imaging, pathology reports, postoperative follow-up, and retrospective reanalysis of preoperative imaging were recorded. Results: Histological abnormality occurred in 14.6% of the patients. In situ carcinoma was diagnosed in 4.5% of the patients, and findings demonstrating increased risk of breast cancer were diagnosed in 13.5% of the patients. More than one lesion demonstrating increased risk of breast cancer was diagnosed in 4.5% of the patients. No invasive carcinoma occurred. Preoperative mammogram was performed for the majority (94.0%) of the patients. Conclusions: We detected a considerable amount of findings in reduction mammaplasty specimens with prognostic value with regard to future breast cancer risk. We recommend histological analysis for reduction mammaplasty specimens and focus attention on systematically performed preoperative imaging.
