Living with Subcutaneous panniculitis-like T-cell lymphoma

A rare lymphoma, a type of blood cancer, that mainly affects the skin with painless nodules under it.

Understanding Subcutaneous panniculitis-like T-cell lymphoma

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare lymphoma that mainly affects the skin.

Lymphomas are cancers that come from white blood cells growing out of control. In SPTCL, multiple painless nodules form in the fat layer under the skin and can cause swelling, called panniculitis. A skin biopsy can diagnose it. It can occur at any time in life.

Signs & symptoms

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

  • Painless lumps under the skin
  • Red raised patches on the skin
  • Fever and chills
  • Tiredness
  • Weight loss
  • Enlarged liver and spleen

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

    Specialists who may be involved include blood and bone marrow specialists, cancer specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

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