Do I Qualify for a Dupixent CTCL Case Review?
If you used Dupixent and were later diagnosed with CTCL, mycosis fungoides, Sézary syndrome, or another related T-cell lymphoma, certain facts may help determine whether your history should be reviewed.
What may matter in an initial review
An initial review may consider whether you used Dupixent, the type of diagnosis you received, when treatment began, when symptoms changed, and when a CTCL-related diagnosis was confirmed. Each inquiry is reviewed individually.
Dupixent was also prescribed for asthma, COPD with eosinophilic phenotype, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, prurigo nodularis, chronic spontaneous urticaria, and bullous pemphigoid. Any approved indication may be relevant to review — not only eczema.
Facts that may be important
CTCL-related diagnosis
Whether your records mention CTCL, mycosis fungoides, Sézary syndrome, or another related T-cell lymphoma.
Timeline and progression
When symptoms changed, when the diagnosis was made, and whether there were concerns about delayed recognition or progression.
Medical records
Pathology reports, dermatology records, oncology records, prescription history, and second opinions may help with later review.
How to think about your timeline
For many CTCL-related inquiries, timing is one of the first things reviewers may look at. A useful timeline may include:
- when Dupixent treatment began;
- what condition Dupixent was prescribed to treat;
- when symptoms changed or worsened;
- when CTCL or another related T-cell lymphoma was first suspected;
- when the diagnosis was confirmed;
- what dermatology, pathology, oncology, or specialist records are available.
You do not need to have every record ready before requesting an initial review. Basic dates and a short description can be enough to start.
When it may make sense to submit information
You may consider requesting an initial review if:
- you used Dupixent before a CTCL-related diagnosis;
- your records mention CTCL, mycosis fungoides, Sézary syndrome, or another related T-cell lymphoma;
- symptoms changed, worsened, or were difficult to diagnose during or after Dupixent treatment;
- you have dermatology, pathology, oncology, or prescription records that may help clarify the timeline.
Each inquiry is reviewed individually.

Frequently Asked Questions
What diagnoses are most relevant to this review?
This review is focused on CTCL and related T-cell lymphoma diagnoses, including mycosis fungoides and Sézary syndrome. Other related T-cell lymphoma diagnoses may also warrant review depending on the medical history.
Why does timing matter in a Dupixent CTCL review?
Timing may help reviewers understand whether Dupixent use came before the diagnosis, whether symptoms changed during treatment, and whether the diagnosis was suspected or confirmed later through dermatology, pathology, oncology, or specialist evaluation.
What if my CTCL was first treated as eczema or another skin condition?
CTCL can sometimes be difficult to distinguish from inflammatory skin conditions. If your diagnosis history involved changing symptoms, delayed recognition, biopsies, second opinions, or specialist evaluation, those details may be helpful in an initial review.
What records may be helpful?
Helpful records may include Dupixent prescription history, dermatology records, biopsy or pathology reports, oncology records, diagnosis records, second opinions, and notes showing symptom changes or progression.
Do I need all of my medical records before contacting MedLaw Group?
No. You can start with basic information. Additional records may be requested later if your inquiry moves forward in the review process.
Does submitting information mean my matter has been accepted?
No. Submitting information requests an initial review only. It does not mean your matter has been accepted and does not create an attorney-client relationship.
