Myxoma valvulae arteriae pulmonalis described by Rokitansky: medicohistorical and clinicopathological aspects.

The bicentenary of the birth of Rokitansky, the first true descriptive pathologist, was celebrated in February 2004. Rokitansky gathered many and important specimens that are now displayed in the Federal Museum of Pathological Anatomy in Vienna. On examining Rokitansky's collection we found a myxoma of the pulmonary valve of a 70-year-old woman who died in 1833. Cardiac myxomas are rare but are the most frequent primary heart tumors, appearing even less frequently on cardiac valves. Modern histology has confirmed Rokitansky's diagnosis on gross pathology. The good condition of this 171-year-old specimen was surprising. Thus, Rokitansky described the myxoma 75 years before Ribbert's first description of a myxoma in this rare localization.
