Coexistence of a Choriocarcinoma and a Gonadoblastoma in the Gonad of a 46,XY Female: A Single Nucleotide Polymorphism Array Analysis
Bibliographic record
Abstract
Females with 46,XY complete gonadal dysgenesis are at significant risk of developing germ cell tumors, mostly gonadoblastomas. We present here the case of 2 half-sisters, sharing the same father, diagnosed with 46,XY complete gonadal dysgenesis. The 1st sister developed a gonadoblastoma and an invasive dysgerminoma, whereas the 2nd sister developed a gonadoblastoma and an invasive choriocarcinoma within the same gonad. No SRY mutation, chromosome abnormalities, or mosaicism were detected in blood. Single nucleotide polymorphism (SNP) profiling of the choriocarcinoma revealed a complex hyperdiploid pattern with gains of 1 to 4 copies of material from several autosomes, as well as the loss of the Y chromosome and a homozygous SNP profile without copy number change for the X chromosome. Our results are in agreement with the recurrent chromosome gains and losses previously published in germ cell tumors, and the coexistence of both tumors within the same gonad suggests that choriocarcinomas may derive from gonadoblastomas.

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.
