0.000What This Code Means
A type of non-Hodgkin lymphoma affecting the skin and follicle center cells in the lymph nodes within the pelvis.
Coding Tips
- •Verify intrapelvic (within pelvis) lymph node involvement is clearly documented
- •Distinguish from other pelvic lymphomas by confirming cutaneous follicle center origin
Clinical Significance
Cutaneous follicle center lymphoma involving intrapelvic lymph nodes represents a deeper spread pattern that is atypical for a primary cutaneous lymphoma. Intrapelvic nodal involvement (iliac, obturator, presacral nodes) suggests the disease may have extended beyond typical regional drainage and should prompt reconsideration of whether the primary cutaneous designation is accurate. Clinical staging and multidisciplinary discussion may be warranted.
Documentation Requirements
- ✓Skin biopsy confirming cutaneous follicle center lymphoma origin
- ✓Cross-sectional imaging documenting intrapelvic lymph node involvement
- ✓Clinical justification for maintaining primary cutaneous classification
- ✓Distinction between intrapelvic and inguinal lymph node groups on imaging
- ✓Complete staging including assessment of other nodal and extranodal sites
