Abstract
BACKGROUND: Pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-PDE), a rare acquired elastolytic disorder, occurs in postmenopausal, elderly women and is characterized by soft, white-yellow papules that localize on the neck and supraclavicular regions and often coalesce into cobblestone plaques. It has no systemic involvement and is histologically distinct from the clinically similar inherited pseudoxanthoma elasticum. CASE SUMMARY: A 64-year-old Caucasian woman presented with a 2-year history of multiple, asymptomatic soft yellow 1- to 2-mm papules on her neck, which were increasing in number. On histopathology, haemotoxylin and eosin stain showed a normal-appearing papillary dermis; however, Verhoeff-van Gieson elastic stain showed absent elastic fibres in the papillary dermis. Papular elastorrhexis was suggested, but given its clinical picture, PXE-PDE was also considered. There was no resolution after 2 courses of intralesional triamcinolone acetonide (0.1 mL of 5 mg/mL). CONCLUSION: PXE-PDE, which is characterized by complete loss or significant reduction of elastic fibres in the papillary dermis, was consistent with our patient's presentation and histologic findings. Papular elastorrhexis, a paediatric cutaneous disorder, was initially considered, but clinicopathologic correlation led to a diagnosis of PXE-PDE. Intralesional corticosteroids was tried as a treatment but was ineffective at improving the condition. This report documents the importance of histopathology and clinicopathologic correlation when differentiating the overlapping variants of fibroelastolytic disease.

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 it
