Vaginal Epithelioid Angiosarcoma
Bibliographic record
Abstract
OBJECTIVE: Epithelioid angiosarcoma of the vagina is a rare variant that can easily be misdiagnosed considering the much higher frequency of epithelial neoplasms at that particular site. MATERIAL AND METHODS: We report the case of a 41-year-old gravida 2, para 1, aborta 1, with no prior history of irradiation, who consulted after the discovery of 3 lesions at the lower right portion of the vagina. RESULT: The lesion consisted of epithelioid cells with high-grade nuclei and prominent nucleoli. These cells expressed CD31, CD34, factor VIII, Fli-1, vimentin, smooth muscle actin, and WT-1. Keratin 8/18 was focally positive. They were immunonegative for keratin AE1/AE3, keratin 34βE12, keratin 7, keratin 20, S100, HMB-45, myogenin, desmin, and human herpesvirus type 8. Polymerase chain reaction-based HPV viral search was also negative. CONCLUSIONS: A broad immunohistochemical panel including antibodies against vascular differentiation markers as well as various cytokeratins allows proper diagnosis of this unusual and aggressive entity.

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.
