Glandular cardiac myxomas: Pathological features and histogenesis

Area of Science:

• Cardiovascular Pathology
• Surgical Pathology
• Oncology

Background:

• Cardiac myxomas (CMs) are the most frequent primary cardiac tumors, typically exhibiting characteristic lepidic cell morphology.
• Uncommon variations in classic histopathological features can complicate the diagnosis of cardiac myxomas.
• Glandular differentiation within cardiac myxomas represents a rare but diagnostically significant finding.

Purpose of the Study:

• To report a rare case of cardiac myxoma with glandular components.
• To discuss the histogenesis and immunohistochemical profile of glandular cardiac myxomas.
• To outline the differential diagnosis for this unusual entity.

Main Methods:

• Histopathological examination of the cardiac myxoma.
• Immunohistochemical staining to characterize cellular components.
• Review of relevant literature on cardiac myxoma variants.

Main Results:

• The cardiac myxoma demonstrated distinct glandular structures alongside typical myxoma features.
• Immunohistochemistry helped elucidate the nature of the glandular components and their relationship to the myxoma.
• The findings highlight the importance of considering rare morphological variants in cardiac myxoma diagnosis.

Conclusions:

• Glandular cardiac myxomas are rare entities that require careful histopathological evaluation.
• Understanding the histogenesis and immunohistochemical features is crucial for accurate diagnosis and differentiation from other tumors.
• This case underscores the diverse morphology of cardiac myxomas and the need for comprehensive diagnostic approaches.
