Human Case of Lobomycosis
Bibliographic record
Abstract
We describe a 42-year-old woman with histologically confirmed lobomycosis, a cutaneous fungal infection rarely reported outside of Latin America.Our case represents the first published report of imported human lobomycosis in Canada and the fifth in an industrialized country.C utaneous fungal infections are rarely reported outside of Latin America.We document the first case of imported human lobomycosis in Canada. The StudyIn February 2001, a healthy, 42-year-old, female geologist from Canada came to her dermatologist with a slowly growing, 1.5-cm diameter, dusky-red, nontender, plaquelike lesion surrounded by keloidal scar tissue on the posterior aspect of her right upper arm (Figure 1).It was located at the site of a scar from a previous excision attempt of a similar lesion 2 years earlier.The original lesion was first noticed while the patient was visiting Southeast Asia in 1996, although she did not seek medical attention until returning to Canada 1 year later.At that time, coccidioidomycosis was diagnosed based on her history of previous travel to a disease-endemic region and on the presence of oval, yeast-like organisms in histologic sections.However, Coccidioides immitis was never cultured from the lesion, and serologic studies for this fungus were negative.After the excision in 1997, nothing was noted further until October 1999, when a small lesion, similar in color to the original one, reappeared under the scar and gradually increased in size.The patient had no other skin lesions and was otherwise asymptomatic.The patient had spent time doing geologic work in various tropical regions over a 7-year period.In 1992-1993, she traveled to the Four Corners region of the United States as well as to California, northern Mexico, and Costa Rica.She lived and worked in the jungles of Guyana and Venezuela for 2 years (1993 and 1994), spending most of her time around the Cuyuni, Essequibo, and Rupununi River areas, although she also spent some time in the Bolivar state of Venezuela.Thereafter, she traveled to Kazakhstan, Indonesia (Irian Jaya), and the Philippines

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.
