Prenatal and postnatal features of mesenchymal hamartoma of the chest wall: case report and literature review.

Mesenchymal hamartoma of the chest wall is a rare, benign chondro-osseous tumor of the bone. Although it most commonly presents at birth or soon after, prenatal detection is rare. We report a case of prenatally detected mesenchymal hamartoma, and provide the rationale, details, and outcomes of our management. The literature is reviewed, with particular attention to prenatal detection and postnatal management options.
