Pigmented cardiac paraganglioma.

Academic Article

Abstract

  • A pigmented left atrial paraganglioma was found at autopsy in a 40-year-old black man who died unexpectedly. The cause of death was ascribed to coronary artery disease. The atrial mass was sharply demarcated and polypoid, measured 4 cm in greatest dimension, and had a cut surface that revealed dark red-brown soft tumor tissue. Histopathologically, the neoplasm exhibited a classic organoid clustering of cells (zellballen) with a prominent capillary network. The chief cells contained a brown-black pigment with histochemical characteristics of melanin. We report a case of pigmented cardiac paraganglioma because of its rarity. To our knowledge, no mention has been made of the presence of pigment in previously reported cases of cardiac paragangliomas.
