Lipoma of the Heart: An Autopsy case report

ABSTRACT

Lipomas of the heart are benign neoplasms and have rarely been described. Due to the fact that they normally cause no symptoms, diagnosis is often purely accidental. Because of the rarity of these tumors, it seems worthwhile to present an example studied at autopsy. It was associated with the sudden death of a 15-year-old boy. The tumor arose from the wall of the left ventricle and occupied the pericardial cavity, measuring 13x7x6 cm in size. The tumor was whitish-yellow, translucent, and soft. Microscopically, the tumor was composed of mature adipose tissue which extended between muscle fibers. This current case, the giant cardiac lipoma is believed to produce disturbances of the conduction system and distrubances of cardiac filling.
