Can a myxoma be malignant?
Myxomas developing in three to four heart chambers are extremely rare and usually considered malignant cardiac tumors, especially when tumors located in other organs were detected (6–8).
Is a myxoma a neoplasm?
No, myxoma is not cancer. In general, tumors are abnormal growths of cells that form a mass. If the tumor cells have the potential to spread and invade other tissues, in a process called metastasis, the resulting tumor is known as a malignant tumor, or cancer.
What does a myxoma secrete?
A myxoma (New Latin from Greek ‘muxa’ for mucus) is a myxoid tumor of primitive connective tissue. It is most commonly found in the heart (and is the most common primary tumor of the heart in adults) but can also occur in other locations….

What does a myxoma look like?
An Atrial Myxoma can be polypoid, round, or oval in shape. They have a gelatinous consistency. They often present with a smooth or lumpy surface and are usually white, yellowish, or reddish.
How common is myxoma?
Myxomas are more common in women. About 1 in 10 myxomas are passed down through families (inherited). These tumors are called familial myxomas. They tend to occur in more than one part of the heart at a time, and often cause symptoms at a younger age.
Are myxomas genetic?
Myxoma is the most common primary cardiac tumor. It is usually sporadic. Less than 10% of myxomas are familial and transmitted in an autosomal dominant way [1–4].
Can myxomas come back?
The recurrence rate of sporadic myxoma is 2% to 3% (2). Gerbode et al described the first case of myxoma recurrence, which occurred several years after surgical removal. Recurrence is usually seen during the first 3 to 4 years, although it can emerge within a few months to several years after surgical excision.
What causes myxoma?
Atrial myxomas are sometimes linked with valve obstruction stenosis and atrial fibrillation. Myxomas are more common in women. About 1 in 10 myxomas are passed down through families (inherited). These tumors are called familial myxomas.
How is a myxoma removed?
Currently, there is no effective medical treatment, and surgical excision of the tumor is necessary. Typically, surgical resection of an atrial myxoma is performed via a median sternotomy with the patient on cardiopulmonary bypass.
How fast do myxomas grow?
A MEDLINE search with the terms “cardiac myxoma and tumor growth” was performed. The calculated growth rate showed an average growth rate of 0.49 cm/month. These reports suggest that the growth rate of myxomas may be faster than is usually thought.
How are atrial Myxomas removed?
Conventional treatment of atrial myxoma is surgical removal by median sternotomy. Minithoracotomy with robotically assisted surgery has been reported, resulting in a shorter length of hospital stay, and it is considered a safe and feasible method for atrial myxoma excision.
Do myxomas grow back?

What is a myxoma?
Myxoma is a noncancerous tumor that arises from connective tissue, which is tissue that connects and supports other tissues all over the body. Most frequently, myxomas are found in the heart and are referred to as cardiac myxomas, which are the most common type of primary cardiac tumors in adults.
Myxomas can be removed through surgical intervention. With a cardiac myxoma, open heart surgery is performed to remove the tumor. The atrial septum, or the wall that separates the left and right upper chambers of the heart, may also be removed depending on the depth of tumor penetration.
What is the incidence of cardiac myxomas?
[Histopathological and immunohistochemical features of cardiac myxomas] Mixomas are the most common primary cardiac tumors with an estimate incidence of 0,5-1 per 10(6) individuals per year.
Which histologic findings are characteristic of cardiac myxomas?
Most cardiac myxomas occur sporadically while approximately 10% of diagnosed cases develop as part of Carney complex. This neoplasm is of uncertain histogenesis, however, endothelial, neurogenic, fibroblastic, and cardiac and smooth muscle cells differentiation has been proposed, and rarely glandular differentiation has been observed.
