Primary Pleomorphic Liposarcoma of the Orbit: A Case Report
Bibliographic record
Abstract
To our knowledge, pleomorphic liposarcoma (PL) of the orbit has only been reported in the literature four times. This rarity makes it more difficult to diagnose and to treat in this clinical setting. A 62-year-old female presented with pruritus, edema, proptosis and diplopia 5 months OS. Imaging revealed an intraorbital mass displacing the globe, with infiltration into the sinus. The tumor was removed and the histological examination revealed a highly cellular tumor with heterogenous histology, with a few vacuolated cells and many malignant features. Immunohistochemistry allowed for the differential diagnosis, resulting in a diagnosis of PL of the orbit. The cells were immuno-positive for S-100 and negative for all other relevant markers. According to the literature, prognosis for this neoplasm is quite poor, and exenteration represents the best treatment option. The patient refused exenteration and radiation therapy, however, at 2 year follow-up, she remained recurrence-free.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
