CD4+, CD56+ Mycosis Fungoides: Case Report and Review of the Literature
Bibliographic record
Abstract
This case report details an 85-year-old woman who presented with mycosis fungoides (MF), clinical stage 1A. Bilateral lesions on the upper thighs were responsive to topical steroid therapy. Biopsies showed band-like dermal infiltrates of medium-sized lymphocytes with marked epidermotropism, including large intraepidermal lymphocytes with nuclear convolutions, consistent with MF. Immunohistochemical staining revealed that the lesional cells were CD56+, but unlike the case in previous reports of CD56+ MF, they also expressed CD4 and T-cell intracellular antigen 1 and did not express CD8. To our knowledge, this is the first description of a case of MF with a CD4+, CD8-, CD56+, T-cell intracellular antigen 1-positive immunophenotype. At 85 years of age, the patient is older than all previously described patients with CD56+ MF. Despite an immunophenotype observed more commonly in aggressive forms of cutaneous T-cell lymphoma, the clinical presentation is that of typical MF. The patient presented with limited disease and after 12 months of follow-up has not progressed beyond stage 1A.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
