A cutaneous myxoma, or superficial angiomyxoma, consists of a multilobulated myxoid mass containing stellate or spindled fibroblasts with pools of mucin forming cleft-like spaces. There is often a proliferation of blood vessels and an inflammatory infiltrate.

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]
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 superficial acral fibromyxoma is a type of myxoma and is a rare cutaneous condition characterized by a mesenchymal neoplasm that typically occurs on the digits of middle-aged adults. [ 1 ] : 1817
A myxoid tumor is a connective tissue tumor with a "myxoid" background, composed of clear, mucoid substance. [1]Atrial myxoma. This tumoral phenotype is shared by many tumoral entities:
Although it is a benign tumour and does not invade neighbouring tissues, it has a tendency to recur after surgical excision so it is termed "aggressive". Recurrence can occur as early as six months from initial resection.
NAME refers to nevi, atrial myxoma, myxoid neurofibromas, and ephelides. [1] Testicular cancer, particularly Sertoli cell type, is associated with Carney syndrome. [7] Thyroid and pancreas cancer may also occur. [8] [9] Although J Aidan Carney also described Carney's triad it is entirely different. [10]
