A Case Report of Papillary Digital Adenocarcinoma With BRAFV600E Mutation and Quantified Mutational Burden
Bibliographic record
Abstract
ABSTRACT: Papillary digital adenocarcinoma (PDA) is a rare eccrine tumor that is most often found on the digits. Few case reports have described PDAs located on atypical sites. It is now accepted that PDAs cannot be distinguished from benign adenomas based on histological features, and it is recommended to excise all of these lesions. Even with excision, recurrence and metastasis rates are high. Only limited genomic analyses have been performed to date, and no driver mutations have been identified. We report a case of a 63-year-old woman with a PDA on the right forearm. Biopsy showed moderate cytologic atypia and mitotic figures. Next-generation DNA sequencing of the tumor showed a BRAFV600E mutation and high tumor mutational burden (5.51 mutations/Mb). This mutation is known for its response to small molecular inhibitors of BRAF and Mitogen-activated protein kinase kinase. Such therapy may be a consideration should our patient develop recurrent unresectable disease.

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.
