Living with Muir-Torré syndrome

A form of Lynch syndrome with oil gland skin tumors and a higher chance of internal cancers, mainly in the digestive tract.

Understanding Muir-Torré syndrome

Muir-Torre syndrome (MTS) is a form of Lynch syndrome with oil gland (sebaceous) skin tumors and internal cancers.

The most common internal site is the digestive tract, with almost half of people having colorectal cancer, followed by the urinary and reproductive tract. Skin tumors may appear before or after the internal cancer. A genetic change gives a person a higher lifetime risk of the skin changes and cancers linked with the condition.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Oil gland (sebaceous) skin tumors
  • Colon cancer
  • Ovarian tumors
  • Basal cell skin cancer
  • Breast cancer
  • Other tumors of the digestive and urinary tracts

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

Diagnosis

  1. Talk with your doctor

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

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Fight Colorectal Cancer may keep lists of experts for this condition.

Quick facts

InheritanceAutosomal Dominant

This condition is caused by changes in the MLH1 or MSH2 genes. It is autosomal dominant, which means a changed copy of the gene from one parent can be enough to cause it.

Also known as: cutaneous sebaceous neoplasms and keratoacanthomas multiple with gastrointestinal and other carcinomas; mlh1-related muir-torre syndrome; mrtes; msh2-related muir-torre syndrome; muir-torre syndrome; multiple keratoacanthoma, muir-torre type
