Living with Disseminated peritoneal leiomyomatosis

A rare, usually noncancerous condition with small smooth-muscle lumps on the lining of the abdomen and nearby organs.

Understanding Disseminated peritoneal leiomyomatosis

Disseminated peritoneal leiomyomatosis (DPL) is a rare condition with nodules of smooth muscle cells on the peritoneum, the lining of the abdominal wall, and on abdominal organs.

It is usually benign (noncancerous), though in rare cases it has become cancerous. It most often affects women of childbearing age. Most women with DPL are pregnant, taking the birth control pill, or have uterine fibroids or estrogen-secreting tumors. Some cases resolve when hormone levels return to normal. Surgery may be suggested based on the size and location.

Signs & symptoms

Some people have no symptoms. When present, GARD lists these:

  • Abdominal pain
  • Pelvic pain
  • Rectal or vaginal bleeding
  • Constipation

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
