A rare case of pulmonary cryptococcal inflammatory myofibroblastic tumor diagnosed by fine needle aspiration cytology
Bibliographic record
Abstract
In a recent outbreak in British Columbia (BC), Canada, Cryptococcus gattii, a rare species of Cryptococcus, was noted to affect primarily immunocompetent hosts and cause limited pulmonary or CNS disease. We herein report a rare case of a pulmonary inflammatory myofibroblastic tumor caused by a Cryptococcus infection, presumed to be of the gattii species, in a 20-year-old immunocompetent college student from Vancouver, BC who presented with a large lung mass. The diagnosis was first made on the fine needle aspirate (FNA) material and was confirmed on the concurrent histologic core biopsy. Cryptococcal inflammatory myofibroblastic tumors have been reported, but neither in the lung nor in the setting of an immunocompetent host. Pulmonary cryptococcosis should therefore be considered in the differential diagnosis of a lung mass, even in an immunocompetent host, especially if the clinical history reveals recent travel to British Columbia where Cryptococcus gattii is endemic.
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 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.
