Nerve sheath mucosa is a rare cancer that occurs in young adults, usually women. It is characterized by single plateau lesions of hard consistency, which slowly grow, reaching even several millimeters. The lesions are most often located on the face, but also often on the limbs. Treatment of myxoma involves surgical excision of the lesion.
Nerve sheath mucus
It is a rare neoplasm affecting the nerve sheath cells and occurs in young patients, most often women. The origin of the mucilage is similar to that of neurofibroma and was defined more than thirty years ago by Reed and Harklin. This neoplasm is painless and is characterized by single, hard lesions that slowly grow in size. Nerve sheath mucosa usually appears on the dermis or subcutaneous tissue, most often on the neck, head, and upper limbs. The lesions are much more rarely located on the chest, lower jaw or back.
Nerve sheath myxoma causes
It is said that the cause of cancer lies in genetics, as these types of changes are most often hereditary. Therefore, burdened people should undergo regular checkups.
Nerve sheath mucus – symptoms
The tumor is characterized by the presence of a few millimeters long and slowly developing tumor, which is most often located on the dermis and subcutaneous tissue. Although the growing myxoma does not cause pain, it causes unpleasant itching. It is with this problem that patients most often report to a doctor.
Diagnosis and treatment of nerve sheath myxoma
In the diagnosis and classification of myxoma, a histopathological examination is used, during which the myxoma is distinguished from other damaged tissues. The most effective method of treating this ailment is to completely excise the infected area and the surrounding tissue. If the sick area is left without taking any action, there is a chance that the disease will recur.
Disease samples sent for examination are small and transparent, and may also resemble small lumps that are easily noticeable. As evidenced by microscopic examinations, changes can be found only in the dermis or in the subcutaneous tissue at the same time.
It is relatively rare that the damage is located only in the subcutaneous tissue, thus adhering to the superficial skeletal muscles. An example is one woman who came to the doctor with an itchy lesion on her finger (about six months after its appearance). The lump was hard and half a centimeter in diameter, showing no unpleasant symptoms.
During the visit, the lesion was excised and then sent to the laboratory for histopathological examination. During this examination, it was revealed that transparent mucus-filled nodules containing stellate cells were present inside the tumor. They were located in the dermis, but gradually expanded and had an unusual shape. Ultimately, an immunohistemic study showed that star cells are susceptible to the influence of proteins that promote cancer. As it turned out, the patient’s family (in a straight line) had previously had benign tumors under the skin. This is quite important information, because the nerve sheath myxoma usually has a genetic basis, so people with this gene should be constantly monitored.
