Myxoma fibrosum is spelled using the phonetic transcription /mɪksoʊmə faɪbroʊsəm/. The word "myxoma" is pronounced with the sound /mɪksoʊmə/, where "x" represents the sound of "ks". The second part of the word "fibrosum" is pronounced with the sound /faɪbroʊsəm/, where "fibro" refers to connective tissue and "sum" means a collection of something. This term is commonly used in medical literature to describe a rare tumor consisting of both myxomatous and fibrous tissue.
Myxoma fibrosum, also known as fibromyxoma, is a rare type of benign tumor that primarily develops in the bone or soft tissue. It is characterized by the formation of excessive amounts of fibrous and myxoid tissue within the affected area.
In the case of bone myxoma fibrosum, the tumor typically arises in the epiphysis or metaphysis of long bones such as the femur, tibia, or humerus. It usually occurs during childhood or early adulthood, with an equal predilection for both genders. Bone myxoma fibrosum often presents as localized pain, swelling, or a palpable mass in the affected area. Radiologically, it appears as a well-circumscribed lesion with a multilocular appearance and a thin rim of cortical bone.
Soft tissue myxoma fibrosum, on the other hand, commonly originates in the deep subcutaneous tissues or fascial planes. It usually presents as a slow-growing, painless mass that may be associated with local tenderness or discomfort. Soft tissue myxoma fibrosum typically affects middle-aged adults, with a slight female predilection. Radiologically, it appears as a well-defined, lobulated mass with heterogeneous signal intensity on magnetic resonance imaging.
Although myxoma fibrosum usually displays a slow-growing and benign nature, local recurrence after surgical excision has been reported. Therefore, complete surgical removal of the tumor is essential to prevent recurrence and potential damage to adjacent structures. In some cases, additional treatment modalities like radiation therapy or chemotherapy may be employed if the tumor displays aggressive behavior or metastasizes.

The word "myxoma fibrosum" is comprised of two components: "myxoma" and "fibrosum".
- "Myxoma" is derived from the Greek word "myxa", which means "mucus". "oma" is a suffix in medicine denoting a tumor or abnormal growth. Therefore, "myxoma" refers to a tumor composed of mucous-like material.
- "Fibrosum" is derived from the Latin word "fibra", meaning "fiber". The suffix "-osus" in Latin means "full of" or "abounding in". Therefore, "fibrosum" refers to a condition or growth characterized by an excess of fibrous tissue.
Combined, "myxoma fibrosum" denotes a tumor that contains both mucous-like material and excessive fibrous tissue.
