Understanding Primary cutaneous follicle center lymphoma

Primary cutaneous follicle center lymphoma is a rare, slow-growing type of skin cancer that develops from B cells.

It appears as one or a group of red patches or lumps, usually on the head, neck or trunk. When there are several, they can grow around hair follicles, randomly, or both. The patches are smooth and do not usually break open.

Signs & symptoms

GARD describes these signs:

  • One or more red patches or lumps
  • Lumps on the head, neck or trunk
  • Smooth skin lesions that don't usually break open

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