A myxoma is a rare benign tumor of the heart. Myxomata are the most common primary cardiac tumor in adults, and are most commonly found within the left atrium near the valve of the fossa ovalis. Myxoma may also develop in the other heart chambers. [1] The tumor is derived from multipotent mesenchymal cells. [1]
[4] [5] Today Diffuse lipoblastoma is the preferred term for lipoblastomatosis. [6] [7] The tumor is rare, accounting for less than 1% of all childhood neoplasm, [8] and it has been found to be more common in males than females. [9] [8] It often presents as an asymptomatic rapidly enlarging mass, occurring more often in the soft tissues of the ...
Lipoblastoma is a type of rare, subcutaneous, benign, fatty tumor, [1] [2] found in infants, and children, more common in males with tendency of local recurrence. Local recurrence can happen in up to 80% of incompletely resected tumours.
Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.

A subset of the primary tumors of the heart are tumors that are found on the valves of the heart. Tumors that affect the valves of the heart are found in an equal distribution among the four heart valves. [2] The vast majority of these are papillary fibroelastomas. Primary tumors of the valves of the heart are more likely to occur in males.
Virchow's metamorphosis — lipomatosis in the heart and salivary glands. Dercum's disease — A rare condition characterized by painful fatty tumors in the adipose tissue commonly associated with obesity.
