Palisaded Neutrophilic and Granulomatous Dermatitis Associated With ASXL1-Mutated Chronic Myelomonocytic Leukemia: A Case Report and Literature Review
Bibliographic record
Abstract
ABSTRACT: Palisaded neutrophilic and granulomatous dermatitis (PNGD) is a relatively rare histopathologic reaction pattern that has been associated with several underlying conditions including rheumatoid arthritis, connective tissue disorders, certain drugs, and hematologic malignancies, particularly chronic myelomonocytic leukemia (CMML). CMML shows features of a myeloproliferative neoplasm and myelodysplastic syndrome. The diagnosis can be supported by identifying an acquired clonal molecular abnormality, most commonly involving TET2, SRSF2, ASXL1, RUNX1, NRAS , or CBL . Rare previous reports have highlighted the association between PNGD and SRSF2 -mutated CMML. In this study, we report the first known case of PNGD-associated ASXL1 -mutated CMML without a coexistent SRSF2 variant.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
