Giant breast hamartoma in a 41-year-old female: A case report and literature review

Abstract

Breast hamartoma is an uncommonly reported benign breast lesion of uncertain cause and pathogenesis. The diagnosis of breast hamartoma by a single method such as mammography, magnetic resonance imaging or sonography is inadequate. In the majority of cases, the breast hamartoma is excised a few years after it has occurred when it is not too big. In the present report, however, a particularly large lesion with a long history is described. Such a case has rarely been reported and shows the necessity of early surgery to reduce trauma as much as possible. Excision of hamartoma was successfully performed and an 11x9x3.5-cm tumor was completely excised. The present study also reviews the literature on breast hamartoma.
