Myxomas are benign tumors that primarily develop in connective tissue, often observed in areas such as the heart, skin, soft tissues, and certain organs. They are characterized by their gelatinous appearance and consist of a mixture of spindled cells, blood vessels, and mucoid material. Myxomas are typically slow-growing and are most commonly found in adults, with a slight predilection for females. These tumors often appear as solitary masses, although multiple myxomas can occur in certain syndromes.
In cardiac myxomas, which are the most commonly encountered subtype, the tumor typically arises in the atrium, particularly the left atrium. Symptoms may vary depending on the location and size of the mass, ranging from asymptomatic cases to manifestations such as dyspnea, chest pain, palpitations, dizziness, and systemic embolization. Surgical excision is the primary treatment for cardiac myxomas to prevent potential complications.
Cutaneous myxomas manifest as small nodules or papules located in the skin, typically overlying bony prominences or areas with significant connective tissue. These tumors may present as sporadic lesions or as part of rare genetic syndromes, such as Carney complex.
Overall, myxomas are noncancerous growths most commonly found in connective tissue, and their specific characteristics depend on the affected location. While treatment usually involves surgical removal, the prognosis for patients diagnosed with myxomas is generally favorable.
