Caudal peduncle mineralized lesion resembling calcinosis circumscripta in a wels catfish Silurus glanis
Bibliographic record
Abstract
This report presents an intriguing case of a mineralized lesion resembling calcinosis circumscripta observed in the caudal peduncle of a wels catfish, housed in a public aquarium in northern Italy. The investigation encompasses a comprehensive analysis of various aspects, including clinical presentation, diagnostic imaging, as well as gross and microscopic pathology, and immunohistochemistry. Histopathology, in particular, highlighted a severe focally extensive granulomatous reaction, confirmed by dense histiocytic inflammatory infiltrates and the massive presence of multinucleated foreign body type giant cells localized around lakes and aggregates of mineralized material. Moreover, the usefulness and limitations of immunohistochemistry and special stains in characterizing fish tissues and cell types are highlighted. Although reported in elasmobranchs and sturgeons, to our knowledge, this is the first description of calcinosis circumscripta in teleost fish and it offers valuable insights into the understanding of similar pathologies in aquatic organisms.

How this classification was reachedexpand
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.
