A type of non-Hodgkin lymphoma affecting the skin and follicle center cells in the lymph nodes of the head, face, and neck area.
Coding Tips
- •Confirm documentation specifies head, face, and/or neck lymph node involvement
- •Distinguish from cutaneous involvement without lymph node involvement
Clinical Significance
Cutaneous follicle center lymphoma involving head, face, and neck lymph nodes indicates that this primary skin lymphoma has extended to involve regional lymph nodes, suggesting a more advanced presentation than skin-limited disease. Head and neck is the most common presentation site for this lymphoma subtype. Despite nodal involvement, cutaneous follicle center lymphoma generally maintains a favorable prognosis compared to systemic follicular lymphomas.
Documentation Requirements
- ✓Skin biopsy confirming cutaneous follicle center lymphoma
- ✓Documentation of head, face, or neck lymph node involvement with imaging or physical exam
- ✓Description of primary skin lesion location and characteristics
- ✓Staging evaluation documenting extent of nodal and cutaneous disease
- ✓Assessment of whether nodal involvement is regional drainage vs. distant spread
