What Is Myxomatous?

Myxoma is a benign tumor that usually has an irregular shape and is jelly-like. More than half of the primary cardiac tumors are myxomas. Three-quarters of myxomas occur in the left atrium. Myxoma of the left atrium usually has a pedicle and swings with the blood flow like a rope ball in the atrium.

Pulmonary myxoma has a histological structure that is similar to that of primitive mesenchyme and contains a protein matrix. Myxomas are more common in subcutaneous tissue, aponeurosis, bone, and muscle; they rarely occur in the lungs.
Etiology and risk factors [Pathology] Tumors are deep in the lung tissue and are clearly demarcated from normal lung tissue. Gross specimen, the tumor is smooth, slightly lobulated, and has a very thin envelope on the surface. A brownish yellow jelly-like substance was seen on the cut surface. Microscopically, the tumor was composed of dense cytoplasm and coarse stellate cells. The nucleus is oval and has small regular chromosomes and nucleoli. Among the stellate cells, there are many sticky, fine-grained basophils, much like mucin. No mitosis was seen. The tumor grew invasively or swelled but did not metastasize.
Symptoms because the tumor is located deep in the lungs, often without clinical symptoms. Even found during X-ray examination. The X-ray signs are round and lobed with neat edges.
The diagnosis of lung resection specimens can be confirmed only by pathological examination.
Treatment method The surgical treatment effect is good, but if the resection is not clean, there is a tendency to relapse.
