Cytogenetic abnormalities in follicular dendritic cell sarcoma: report of two cases and literature review.
Bibliographic record
Abstract
BACKGROUND: The identification of chromosomal abnormalities in many hematopoietic and mesenchymal neoplasms has contributed significantly to classification systems. Follicular dendritic cell (FDC) sarcoma is an intermediate-grade malignancy with morphological and immunophenotypic features of follicular dendritic cells. Available data on genetic changes in this neoplasm are limited, with only isolated case reports of cytogenetic abnormalities. CASE REPORT: We reviewed histological, immunophenotypic and cytogenetic findings in two cases of FDC sarcoma. The two cases of FDC sarcoma, were observed in female patients, one was nodal and one extranodal and they exhibited relatively complex karyotypes, characterized by structural abnormalities and loss of multiple chromosomes. One patient had several disease recurrences. At the last follow-up both patients were alive with no residual disease. CONCLUSION: The cytogenetic findings in these two cases, coupled with the few previously described abnormal karyotypes, suggest that FDC sarcoma is cytogenetically diverse.

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.
