fibromatosis

Introduction

Introduction to fibromatosis Fibromatosis is a tumor derived from fibrous tissue with an incidence of 1.37% of soft tissue benign tumors. Tumors can occur in large muscles in any part of the body. The aponeurosis of the rectus abdominis and adjacent muscles of the abdominal wall is most common, occurring during pregnancy and late pregnancy. Abdominal wall outsiders are more common in men, but in the scapula, thighs and buttocks. According to the age and location of the disease, it mainly includes juvenile fibromatosis, cervical fibromatosis, fibromatosis in infants, fibromatosis in infants, and fibromatosis. The age of onset is mostly 30 to 50 years old, and children and adolescents are not uncommon. basic knowledge The proportion of illness: 0.03% Susceptible people: no specific population Mode of infection: non-infectious Complications: osteofibrosarcoma multiple myeloma chondrosarcoma

Cause

Cause of fibromatosis

Fibromatosis is a fibrous tissue tumor derived from muscle, aponeurosis, fascia and collagen. The pathology is benign or low-grade, but the tumor has no capsule, invasive growth, and obvious malignant biological behavior. Is stubborn multiple recurrence, but very few distant metastasis, the recurrence rate is 25 ~ 57%, the recurrence time is more than 1 month to 1 year after surgery, or even more than 10 years, so this type of tumor is also called invasive fiber. Tumor disease, multiple recurrences, can lead to a wider range of lesions, and unsustainable growth, invading vital organs and endangering life.

Microscopically, the tumor is rich in collagen fibers, the lesion is not enveloped, and there is no boundary with the surrounding tissue. Sometimes the surrounding tissue is included in the lesion, mitosis is rare, capillaries and fat cells are rare, and a few cases of recurrence may be fibrosarcoma. Morphological change.

Symptom

Symptoms of fibromatosis Common symptoms Slow growth of fibrotic pain

1. The tumor is located in the deep tissue, with no obvious symptoms or slight discomfort, slow growth, irregular shape or elliptical shape, and its long diameter is consistent with the direction of the affected muscle fibers. The size of the tumor is related to the length of the disease, ranging from several centimeters to More than ten centimeters, the tumor perimeter is unclear, the surface is smooth, no tenderness, the texture is tough as rubber, and the longitudinal direction of the muscle is more fixed, while the lateral movement is slightly movable, and there is no adhesion to the skin. The huge tumor can affect the activity and compress the nerve.

2. Under the microscope, the tumor is rich in collagen fibers, the lesion has no capsule, and there is no boundary with the surrounding tissue. Sometimes the surrounding tissue is included in the lesion, nuclear fission is rare, capillaries and fat cells are rare, and a few recurrence cases may occur. Morphological changes in sarcoma.

Examine

Examination of fibromatosis

X-ray examination: a shadow with a reduced density, calcified spots or floc-like patches scattered within the lesion.

Microscopic examination: The tumor is rich in collagen fibers, the lesion is not enveloped, and there is no boundary with the surrounding tissue. Sometimes the surrounding tissue is included in the lesion, mitosis is rare, capillaries and fat cells are rare, and a few cases of recurrence may be fibrosarcoma. Morphological change.

Diagnosis

Diagnosis and diagnosis of fibromatosis

The tumor is located in the deep tissue, with no obvious symptoms or slight discomfort, slow growth, irregular shape or elliptical shape, and its long diameter is consistent with the direction of the affected muscle fibers. The size of the tumor is related to the length of the disease, and the diameter ranges from a few centimeters to a dozen. Cm, the circumference of the tumor is unclear, the surface is smooth, no tenderness, the texture is tough as rubber, and the longitudinal direction of the muscle is fixed, while the lateral direction is slightly movable, and there is no adhesion to the skin. The huge tumor can affect the activity and compress the nerve.
