Cutaneous meningioma
Cutaneous Meningioma
Cutaneous meningioma (pronounced: kyu-tay-nee-us men-in-jee-oh-ma) is a rare form of meningioma, a type of tumor that arises from the meninges, the protective layers of tissue that cover the brain and spinal cord. Unlike most meningiomas, which are found inside the skull or spinal column, cutaneous meningiomas develop in the skin or subcutaneous tissue.
Etymology
The term "cutaneous meningioma" is derived from the Latin "cutis" meaning skin, and the Greek "meninx" meaning membrane, and "oma" meaning tumor. Thus, it refers to a tumor of the meninges that is located in the skin.
Symptoms
Cutaneous meningiomas often present as a solitary, slow-growing, painless mass. They are most commonly found on the scalp, but can occur anywhere on the body. In some cases, they may be associated with neurofibromatosis type 2, a genetic disorder that causes the growth of noncancerous tumors in the nervous system.
Diagnosis
Diagnosis of cutaneous meningioma is typically made through a combination of physical examination, imaging studies such as MRI or CT scan, and histopathological examination of a biopsy specimen. The tumor cells often show characteristic features such as whorled patterns and psammoma bodies.
Treatment
Treatment for cutaneous meningioma usually involves surgical removal of the tumor. In some cases, radiation therapy may be used if the tumor cannot be completely removed or if it recurs after surgery.
Prognosis
The prognosis for cutaneous meningioma is generally good, as these tumors are usually benign and slow-growing. However, recurrence after treatment is possible, and in rare cases, these tumors can become malignant.
