What is a Lipoleiomyoma?

What is a Lipoleiomyoma?

Lipoleiomyoma is a very rare lesion of the uterus occurring primarily in obese perimenopausal and post menopausal patients. The tumor consists of long intersecting bundles of bland, smooth muscle cells admixed with nests of mature fat cells and fibrous tissue.

What causes Lipoleiomyoma?

Lipoleiomyomas are composed of variable amounts of smooth muscle, fat cells and fibrous tissue. Fatty metamorphosis of smooth muscle cells of leiomyomas is the most likely cause for their development.

What is red degeneration of fibroid?

Red degeneration is a hemorrhagic infarction of the uterine leiomyoma, which is a well known complication, especially during pregnancy. Red degeneration occurs in 8% of tumors complicating pregnancy, although the prevalence is about 3% of all uterine leiomyoma.

Is myometrium the uterus?

The muscular outer layer of the uterus. The organs in the female reproductive system include the uterus, ovaries, fallopian tubes, cervix, and vagina. The uterus has a muscular outer layer called the myometrium and an inner lining called the endometrium.

How is Lipoleiomyoma treated?

Lipoleiomyomas when small and asymptomatic usually do not require treatment and are clinically similar to leiomyomas. Treatment is similar to leiomyomas and is dependent on the clinical symptoms and the size/location of the lesion. Uterine artery embolization or surgical excision can be performed, as indicated 1.

What is the treatment for bulky uterus?

Most causes of an enlarged uterus do not require treatment, although some women may need medication for pain relief. Birth control pills and intrauterine devices (IUDs) containing progesterone can ease the symptoms of heavy menstrual bleeding. In very severe cases, some women may need a hysterectomy.

What is fibroid degeneration like?

Symptoms of Uterine Fibroid Degeneration Acute abdominal pain lasting a few days to a few weeks. Swelling of the abdomen. Fever in addition to other symptoms. Bleeding during pregnancy, resulting from a type of degeneration called necrobiosis.

What are the signs of a degenerating fibroid?

Fibroid Degeneration Symptoms

  • Longer, more frequent, or heavy menstrual periods.
  • Menstrual pain (cramps)
  • Bleeding between periods.
  • Anemia (from blood loss)
  • Pain in the abdomen or lower back (often dull, heavy, and aching, but may be sharp)
  • Pain during sex.
  • Difficulty urinating or frequent urination.

What is the main function of myometrium?

The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes) but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions.

Where is the myometrium located?

The uterus is an inverted pear-shaped muscular organ of the female reproductive system, located between the bladder and the rectum. It functions to nourish and house the fertilized egg until the unborn child is ready to be delivered. Encyclopædia Britannica, Inc.

Do fibroids contain fat?

Lipoleiomyomas [Figure 15] are rare fat-containing fibroids, with a reported prevalence of between 0.005 and 0.2%. [32] They are benign and present with the same symptoms as uterine fibroids. The most likely cause is thought to be fatty metamorphosis of the smooth muscle cells of a leiomyoma.

What kind of tumor is a lipoleiomyoma?

Uterine lipoleiomyomas result from degeneration of smooth muscle cells in an ordinary leiomyoma and represent a rare benign tumor of the uterus 1. Lipoleiomyomas have a reported incidence of 0.03-0.20% and are typically found in postmenopausal patients with typical uterine leiomyomas 2.

Can a lipoleiomyoma mimic an angiomyolipoma?

Angiomyolipomas may mimic lipoleiomyoma, degenerated myoma and vascular leiomyoma with a fat component (16). Denovo growth of a large preperitoneal lipoleiomyoma of the anterior abdominal wall. INTRODUCTION: Lipoleiomyoma is a rare neoplasm consisting of smooth muscle and mature adipocytes.

What are smooth muscle cells in uterine lipoleiomyoma?

Pathology. Many considered a uterine lipoleiomyoma as a distinct variety of leiomyoma. Histologically, it is composed of variable amounts of adipocytes and smooth muscle cells, separated by thin fibrous tissue. The exact etiology is not well known, but is thought to represent fatty metaplasia of the smooth muscle cells of a leiomyoma.

What is the incidence of lipoleiomyoma in postmenopausal women?

Lipoleiomyomas have a reported incidence of 0.03-0.20% and are typically found in postmenopausal patients with typical uterine leiomyomas 2.
