“…The tumor, histologically, resembles umbilical cord [12]. These tumors can occur in a variety of locations including the heart, subcutaneous and aponeurotic tissues, bones, genitourinary tract, skin, retroperitoneum, intestine, pharynx, joints and skeletal muscles [15].…”

Myxoma is a neoplasm of mesenchymal origin composed of undifferentiated stellate cells in a myxoid stroma. This tumor can develop in a variety of locations. Myxomas that arise from skeletal muscles are called intramuscular myxomas. They usually occur in large skeletal muscles. Only ten cases of these benign tumors involving the neck muscles were reported in literature. Of them, only three were located at the paraspinal muscles. A 64-year-old woman presented with occiptal and neck pain over 5 years noted an expansive painful lesion located at posterior cervical region with progressive volume increase in the last 12 months. Image exams revealed a large mass located in the left posterior region of the neck in contact with the C2, C3 and C4 laminae with no invasion of the vertebrea. Tumor total removal was performed through normal muscle margins and the vertebral periosteum was scraped. The tumor was encapsuleted, lobulated with a gray-white appearance. The histological examination yielded the diagnosis of intramuscular myxoma. Follow-up at 1 year showed complete resolution of preoperative symptoms and no evidence of local recurrence. In conclusion, although rare, intramuscular myxoma should be included in differential diagnosis of cervical paraspinal tumors. We reported the fourth case of intramuscular myxoma in the paraspinal musculature of the neck. Despite its benign characteristics, local recurrence was reported after subtotal resection. Tumor total removal should be the goal of surgery.

“…The most frequently involved site was the posterior neck in nine patients, followed by the masseter muscle in four patients. Most cases were sporadic; however, one patient had multiple lesions [ 10 ]. The maximum length of the tumor ranged from 0.6 to 15.0 cm, and the tumor in the present case was the second smallest.…”

Myxoma is a benign tumor of mesenchymal origin. It frequently occurs in the muscles of the hip and extremities; however, it rarely occurs in the head and neck region. This report describes the second case of an intramuscular myxoma of the tongue. A 23-year-old woman was referred to our institution for the diagnosis and treatment of a left tongue lesion. T2-weighted magnetic resonance imaging revealed an 8 × 6 -mm mass in the tongue. Based on a clinical diagnosis of a tongue tumor, excisional biopsy was performed under general anesthesia. The histopathological diagnosis was an intramuscular myxoma. The postoperative course was uneventful, and there was no evidence of tumor recurrence 3 years after surgery.

“…Myxomas are benign mesenchymal tumors of fibroblastic origin which produce excess mucopolysaccharide, are incapable of producing mature collagen, and histologically resemble the umbilical cord [4,5]. To date, a definitive etiology for intramuscular myxomas has not yet been described; however, it is commonly thought that malfunctioning fibroblasts are responsible for both the presence of immature collagen fibers and the abundance of glycosaminoglycans [6].…”
