Hepatosplenic mucormycosis due to <i>Rhizomucor pusillus</i> identified by panfungal PCR/sequencing of ribosomal ITS2 and LSU regions in a patient with acute myelogenous leukemia: A case report
Bibliographic record
Abstract
Background: Angioinvasive Rhizomucor pusillus infection with dissemination to the liver and spleen is exceedingly uncommon, representing less than 1% of reported cases of mucormycosis. Methods: Diagnosis of mucormycosis is often difficult using conventional methods that rely on broad-based non-septate hyphae present on histologic examination and morphological identification of the cultured organism. Our laboratory also uses an in-house panfungal molecular assay to rapidly diagnose invasive fungal infection when conventional methods do not provide definitive results. Results: Herein we present a case of disseminated mucormycosis with hepatosplenic involvement in a 49-year-old female with acute myelogenous leukemia following induction chemotherapy. But in this case repeated tissue biopsy cultures were negative. R. pusillus infection was diagnosed using an in-house panfungal PCR/sequencing assay based on dual priming oligonucleotide primers. Conclusions: New molecular assays facilitate prompt diagnosis of invasive fungal infections.

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.
