Integrated imaging of breast hamartoma: two case reports

Hamartoma of the breast is an uncommon, benign, slow-growing mass usually diagnosed in women in the fourth and fifth decade of life undergoing mammography (MX). Here we report two cases of hamartoma of the breast assessed by integrated MX, ultrasonography and magnetic resonance imaging (MRI) examination. Case 1 was an asymptomatic 47-year-old woman who had never been screened previously. A 90 mm mass was found in her left breast on MX. Case 2 was a 35-year-old woman with pain in her right breast where a 50 mm mass was found on MX. Both patients underwent MRI examination. Breast MRI is an adjunct to MX that can confirm hamartoma diagnosis and exclude rare malignant transformation.
