Huge myoid hamartoma of the breast treated with reduction mammaplasty: report of a case

Breast hamartoma is an uncommon benign tumor characterized by the variety of component tissues. Adipose tissue, mammary glands, and fibrous tissue in various proportions are the main components and form a well-circumscribed mass. Myoid (muscular) hamartoma is an extremely rare subtype of breast hamartoma, which contains an additional smooth muscle component. Inadequate breast contour and nipple-areola complex malposition and expansion can occur after resection of a large myoid hamartoma. Immediate mammaplasty for the affected breast, using the dermoglandular flap technique, is required to provide symmetry of the bilateral breasts. We report a case of myoid hamartoma that was larger than ever documented before. An acceptable aesthetic result was achieved by resection and application of reduction mammaplasty in a single-stage operation.
