​Pathology - Cardiac Neoplasms ( Atrial Myxoma and Rhabdomyoma)
Myxomas: The etiology of this condition is still unknown, although around 10% of cases are attributed to an autosomal dominant trait. It is typically observed in adults.
Rhabdomyomas are commonly observed in infants and young children and are often associated with tuberous sclerosis.

Study of diseases and their effects on the body. 
Myxoma is typically located in the vicinity of the fossa ovalis in LA. It commonly takes the shape of a pedunculated mass and is made up of spherical myxoma cells and smooth muscle cells embedded in a mucopolysaccharide matrix.
Rhabdomvoma refers to a medical condition. The myocardial mass is grayish in color and extends into the ventricle. It is made up of spider cells, which are polygonal cells containing vacuoles filled with glycogen. These cells are divided by strands of cytoplasm.

Symptoms and signs
Myxoma is a condition that occurs when the function of the mitral valve is compromised by a ball-valve obstruction, leading to symptoms such as difficulty breathing or fainting. It can also cause a stroke if an embolus occurs. A diastolic "tumor plop" can be detected during a physical examination. Other symptoms of Myxoma include fever, weight loss, joint pain, fatigue, heart failure, and anemia.
Rhabdomyoma: Manifests with symptoms indicative of heart chamber blockage.

Therapeutic interventions 
Myxoma: Typically non-malignant and can be removed with surgery.
Rhabdomyoma: Frequently undergo spontaneous regression and can therefore be managed conservatively; surgical excision may be necessary in cases of significant blockage or persistent arrhythmias.
Cardiac tumor is most frequently caused by metastasis. Cardiac sarcomas are few, although significant when they manifest. Malignant tumors are neoplasms that frequently undergo metastasis.
