Glomus Tumor Presenting as a Periurethral Mass
Bibliographic record
Abstract
OBJECTIVES: Glomus tumors, a neoplasm arising from the glomus body, usually occur in the extremities with a particular predisposition to a subungual site. Glomus tumors are exceedingly rare in the external genitalia. In this case, the origin of a periurethral mass proved to be a glomus tumor. MATERIALS AND METHODS: A 61-year-old woman presented with postmenopausal vaginal bleeding. Clinical examination revealed a focally ulcerating, soft periurethral mass. A subsequent wedge biopsy of a periurethral, submucosal tumor was examined microscopically using both hematoxylin and eosin stains and an extensive immunohistochemical panel. RESULTS: The initial histopathologic differential diagnosis of the wedge biopsy included several neoplasms, but final analysis, including immunohistochemistry (vimentin, desmin, and calponin positivity), concluded that the lesion was a glomus tumor. CONCLUSIONS: Periurethral masses are rare and may be caused by a large number of neoplastic and nonneoplastic lesions. This case of glomus tumor presenting as a periurethral mass may be the only third reported occurrence.

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.
