Overview
Cardiac myxomas are classified by the WHO histological classification of tumors of the heart, as "Benign tumors and tumor-like lesions" and categorized into a type of pluripotent mesenchymal tumor. According to the World Health Organization, cardiac myxoma is a neoplasm composed of stellate to plump, cytologically bland mesenchymal cells set in a myxoid stroma. [1] [2][3]
Classification
Based on the location and biological behavior of symptoms, cardiac myxomas may be classified into two groups: typical and atypical. In typical cases, cardiac myxomas are almost always single, and there is a striking predilection for the left atrium, with approximately 75-86% occurring there.
In atypical cases, presentation is usually early and multicentricity is more common. They are more frequently located on the right side of the heart (38%), or in the left ventricle (5%). [4] [3] There is also recurrence after surgical excision (12%–22%) and an association with other conditions, such as the Carney complex. Among patients with this syndrome, they tend to be younger, male, and have familial predisposition for cardiac myxoma.[5]
Distribution:
- Atria (95%)
- left (75%)
- right (20%)
- Ventricles (5%)
There is no established histological differentiation both type of myxomas (typical and atypical).[6]
