How to diagnose fibroid disease

Fibroma is formed by the proliferation of fibroblasts. The disease originates from any layer of subcutaneous and submucosal connective tissue. It is divided into hard and soft types according to the amount of fiber components it contains. It generally grows slowly. So how to diagnose fibroma disease? What are the symptoms? Let's analyze it in detail.

Fibromas are composed of well-differentiated subcutaneous connective tissue. They are common in adults aged 40-50 years. They grow slowly and generally stop growing after they develop to a certain size. Fibroids, especially desmoids in the abdominal wall muscles, can become malignant and should be completely removed as soon as possible.

Fibroids are usually well circumscribed.

1. Desmoid tumor

Most of them are round and hard, with dry cut surface, white or yellowish white, and the fiber bundles can be vaguely seen in cross section and longitudinal section when carefully observed. Desmoid tumors not only have more glial fibers, but also the nuclei of connective tissue cells are mostly spindle-shaped.

2. Soft fibroma

The cross-section is spongy, with many blood vessels and often edema. The lymph contained in it can coagulate into a gelatinous state, with fewer colloid fibers and looser cell arrangement.

The fibroma on the skin is round or oval in appearance and has a good shape. It may develop ulcers and secondary infections on the surface and is homogeneous grayish white in color.

3. Others

If the connective tissue of a fibroma is mixed with mature fat, bone, cartilage or myxoid connective tissue, and the amount is less than half of the connective tissue, they can be called lipofibroma, osteofibroma, chondrofibroma and myxofibroma respectively. However, tumors mixed with bone tissue and myxoid connective tissue often have the potential to become malignant sarcomas, so attention should be paid.

Types of fibroids:

Xanthofibroma

It is common in the dermis or subcutaneous layer of the trunk and proximal upper arm. It often arises from small papules after trauma or itching. The lumps are hard with unclear edges. Because they are accompanied by internal bleeding, they contain hemosiderin and are dark brown. If the tumor is larger than 1 cm and grows rapidly, it should be suspected to be fibrosarcoma and must be completely removed surgically.

Dermatofibrosarcoma protuberans

Located in the dermis, protruding from the body surface, with smooth surface skin, shaped like keloid, it is prone to occur on the trunk, is of low grade malignancy, has a pseudocapsule, is prone to recurrence after resection, and multiple recurrences increase the malignancy. It can metastasize through the bloodstream, and the tumor lesions containing enough normal skin and deep adjacent fascia should be removed as soon as possible.

zona fibroma

The abdominal wall muscles are formed by reparative hyperplasia after trauma or birth injury, have no obvious capsule, and are suitable for surgical removal.

symptom:

1. The tumor is located in deep tissues, with no obvious symptoms or slight discomfort, and grows slowly.

2. The shape is irregular or oval, and its long diameter is consistent with the direction of the affected muscle fibers.

3. The size of the tumor is related to the duration of the disease, and its diameter ranges from a few centimeters to more than ten centimeters.

4. The tumor has unclear perimeter, smooth surface, no tenderness, and is tough like rubber. It is relatively fixed longitudinally to the invaded muscle, but can move slightly laterally, and has no adhesion to the skin. Huge tumors can affect movement and compress nerves.

diagnosis:

1. It is a relatively common benign tumor of well-differentiated fibrous connective tissue. It is more common in young people, solitary, mostly millimeters to several centimeters, and painless.

2. Often found accidentally, hard, with clear boundaries, movable, and slow growth. It can occur in subcutaneous tissues of all parts of the body. For example, tumors that grow in the breasts of young women and are mainly glandular are called fibroadenomas, and tumors that grow in muscles with muscle tissue are called fibromyomas. When multiple tumors occur, they are called tumor-like lesions, called fibromatosis. For example, congenital systemic fibromatosis is "benign" in morphology, and new lesions that appear in important organs can also lead to death. If they grow in the compressed area of ​​the sacrum, they will grow rapidly, erode, ulcerate, bleed, and become malignant.

3. Desmoplastic fibroids (ligament-like tumors) that grow on the rectus abdominis of the abdominal wall, neck, trunk, and limbs are more common in women. If not radically removed, they are very likely to recur, but they do not metastasize, so they are called borderline tumors.
