Hamartoma of the breast: surgical treatment and reconstruction. Case report.

Hamartoma of the breast is a rare and usually benign tumour with a variable growth pattern. Slowly increasing breast asymmetry is the most common clinical finding. Smaller hamartomas are often diagnosed on mammography. Simple enucleation and secondary expansion of the breast tissue are often sufficient to restore breast symmetry but sometimes, as in the two cases presented, reconstruction is necessary.
