What Is Platysma?

Myofibromas are fibrous tissue tumors derived from muscle, aponeurosis, and fascia and rich in collagen. It is a benign tumor composed of fibrous connective tissue. It is more common in the slow growth of the skin, usually the smaller edges are clear, and the surface is smooth and the texture is harder. It can promote the fibromyoma, fibroadenoma, fibrolipoma, etc. if mixed with other components of the mood. The incidence was 1.37% of benign soft tissue tumors. Tumors can occur in large muscles in any part of the body. The rectus abdominis and the aponeurosis of adjacent muscles are the most common. They occur in pregnancy and late pregnancy. Those outside the abdominal wall are more common in men, and are more common in the scapula, thigh and hips. The age of onset is mostly 30 to 50 years old, and children and adolescents are not uncommon. The cause of this disease is unknown, and may be related to trauma, hormones and genetic factors.

Myoma

Fibroma is also called muscle fibroma. More common under the skin, slow growth, generally smaller, clear edges, smooth surface, hard texture, can promote. When mixed with other components, they become fibroids, fibroadenomas, fibrolipomas, and the like. Fibroids, especially desmoids in the abdominal muscles, can be malignant and should be completely removed as soon as possible.

Myoma

Lumps grow slowly and generally transfer without much money. Other symptoms are too poor. They are often found under the skin, have no adhesion to the skin, and have a certain degree of activity. Slow growth, usually small, normal skin smooth heart can feel the smooth rounded mass under the skin. The state of no tenderness has clearly seen the texture is hard. A few have malignant biological behaviors, relapse stubbornly many times, but rarely distant metastases. The recurrence rate was 25 to 57%. The recurrence time is mostly from 1 month to 1 year after operation, even up to more than 10 years, so this type of tumor is also called invasive fibromatosis. Repeated recurrences can lead to a wider range of lesions, with irrepressible growth, invasion of vital organs, and life-threatening.

Myoma tumor pathology

The tumor was found to be rich in collagen fibers under the microscope. The lesion had no envelope and had no boundary with the surrounding tissues. Sometimes the surrounding tissue was included in the lesions. Nuclear fission was rare, and capillaries and fat cells were rare. Morphological changes of fibrosarcoma can occur in a few cases of recurrence.

The tumor is located in deep tissues, without noticeable symptoms or slight discomfort, and grows slowly. Irregular shape or oval shape, its long diameter is consistent with the direction of affected muscle fibers. The size of the tumor is related to the length of the disease, ranging from a few centimeters to a dozen centimeters in diameter. The perimeter of the tumor is unclear, the surface is smooth, there is no tenderness, and the quality is tough like rubber. It is relatively fixed in the longitudinal direction with muscle invasion, but slightly movable in the horizontal direction, without adhesion to the skin. Giant tumors can affect activity and compress nerves.

Treatment and prevention of myoma

There are several types of myomas.

a. Yellow fibroids: occur in the dermis or subcutaneous layer of the trunk, near the upper arm, often from small pimple after trauma or pruritus, hard masses, unclear edges, accompanied by internal bleeding, containing hemosiderin, dark brown, If the tumor is more than 1 cm and grows faster, fibrosarcoma should be suspected, and the surgical resection must be thorough.

b. Carcinoid fibrosarcoma: located in the dermis layer, protruding from the body surface, the surface of the skin is smooth, looks like keloids, occurs in the trunk, is low-grade malignant, has a pseudo-envelope, is easy to relapse after resection, and the recurrence of malignancy increases repeatedly. Hematogenous metastases should be removed as early as possible with sufficient normal skin and deep adjacent fascia.

c. Banded fibroids: abdominal wall muscles are formed by trauma or postpartum repair proliferative repair without obvious capsules, and should be surgically removed.
