Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is a dense, mobile mass, rarely > 1 cm, with a consistency that closely resembles the chordae tendineae
A
fibroma
B
myxoma
C
papillary fibroelastoma
D
rhabdomyoma
Explanation: 

Detailed explanation-1: -Papillary fibroelastomas are one of the most common types of primary cardiac tumors. They are increasingly recognized as the spatial resolution of imaging modalities improves. Also, they are a potential cause of transient ischemic attacks, strokes, myocardial infarction, and sudden death.

Detailed explanation-2: -ANSWER: Fibroelastomas are formally known as papillary fibroelastomas, or PFEs, and are sometimes called cardiac papillomas. These small, noncancerous tumors develop in the heart-most often on one of the valves located between the heart chambers.

Detailed explanation-3: -Papillary fibroelastomas are the most common benign neoplasms of the cardiac valvular structures, and they are being recognized more frequently because of higher-resolution imaging technology. Papillary fibroelastomas are associated with substantial complications that are secondary to systemic embolism.

Detailed explanation-4: -Papillary fibroelastomas are the most commonly diagnosed tumor of the heart valves [4]. They arise from the heart valves, with the aortic and mitral valves the most common sites of involvement. The differential diagnosis includes vegetation, thrombus, or myxoma.
