Erythropoietic Protoporphyria Masquerading as Angioedema in a 4-Year-Old Female
Bibliographic record
Abstract
Angioedema is a common presentation with a broad differential, including rare disorders with which an allergist must be familiar. Our objective was to report a case of swelling of the hands and feet mimicking angioedema with hepatomegaly in a 4-year-old girl. The patient was evaluated for painful swelling of the hands and feet after exposure to sun. Examination revealed edema and erythema of the extremities and hepatomegaly. Laboratory evaluation included elevated liver transaminases and plasma protoporphyrin, with normal urine porphyrins. Liver biopsy confirmed the diagnosis of erythropoietic protoporphyria, a disorder of heme biosynthesis in which patients may present with photosensitivity and angioedema. It is important for allergists to recognize this entity in patients with cutaneous disorders of unclear etiology in order to prevent possible life-threatening sequelae.

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.
