Calf fibroma

Some people may find small bumps under their skin, which usually do not hurt or itch, but can make people very worried. Calf fibroma is a very common problem, but it is generally benign and can occur in anyone. The types of fibroids that occur vary according to age, but no matter what age group you are in, it is best to go to the hospital for a check-up to make sure it is not malignant.

This situation is related to individual factors. It is a benign tumor that can be treated surgically under local anesthesia. The damage is small and the healing is fast.

Depending on the age and location of onset, it mainly includes juvenile fibromatosis, cervical fibromatosis, infantile fibromatosis, infantile myofibromatosis, lipofibromatosis, etc. The age of onset is mostly between 30 and 50 years old, and it is also common in children and adolescents. Tumors can occur in large muscles anywhere in the body, most commonly the rectus abdominis muscle of the abdominal wall and the aponeurosis of its adjacent muscles, and are more common during pregnancy and late pregnancy. Those outside the abdominal wall are more common in men, and are prone to occur in the scapula, thigh and buttocks.

Clinical manifestations

According to the age of onset and the affected parts, it is divided into:

1. Juvenile fibromatosis

Occurs in children and young people.

2. Cervical fibromatosis

It refers to a type of fibromatosis that manifests at birth or shortly after birth and involves the lower third of the sternocleidomastoid muscle, sometimes bilaterally. Cervical fibromatosis is often associated with various congenital anomalies.

3. Infant and young child fibromatosis

It is a type of fibromatosis that usually occurs only in childhood. The typical site is the outer side of the finger (toe) end, but it can also occur in other places outside the finger (toe), such as the mouth and breast. This disease is often multiple and often occurs at birth or within 2 years of age.

4. Infantile myofibromatosis

It is a single or multiple nodular lesion occurring in the skin, soft tissue or bone, which may be limited to the above-mentioned parts or may be accompanied by the involvement of internal organs. The disease mostly occurs before the age of 2 years, and about 60% are congenital. This disease can also occur in adults. Single cases are more common in males, while multiple cases are more common in females. Familial disease is known, and evidence of autosomal dominant inheritance has been found.

5. Lipofibromatosis

It is a subtype of infantile fibromatosis and local recurrence is common.

6. Multiple hyaline fibromatosis

It is a morphologically specific, familial form of multiple fibromatosis affecting children that has no manifestations at birth and may be caused by congenital metabolic abnormalities.

7. Others

Penile fibromatosis, palmar fibromatosis, plantar fibromatosis, cicatricial fibromatosis and post-irradiation fibromatosis. Fibromatosis associated with multiple colon polyposis and, occasionally, multiple bone tumors is called Gardner syndrome.

treat

The treatment option should be timely and thorough surgical resection, including a wider area around the affected tissue, and sometimes the entire affected muscle needs to be removed. Only in very rare cases is amputation forced due to its local invasiveness. Radiotherapy may be effective for local control of the disease and can be used after conservative surgery. Endocrine therapy, such as tamoxifen, has been successful in some cases. Young patients and patients with larger tumors have higher recurrence rates.
