Accessory Liver Lobe with Mesothelial Inclusion Cysts in an Omphalocele: A New Malformative Association
Bibliographic record
Abstract
Mesothelial inclusion cysts represent benign lesions that have been reported in a wide variety of locations. Peritoneal cysts are observed and visceral involvement has been described, notably of intraperitoneal organs such as the spleen and the testis. We report the cases of 2 neonates who underwent surgical management of an omphalocele. The hernial sac contained an accessory liver lobe, displaying in both cases multilocular mesothelial inclusion cysts. The hobnail cells lining the cysts exhibited calretinin and cytokeratin immunohistochemical reactivity, as well as focal D2-40 reactivity. One of the cases occurred in the setting of a Beckwith-Wiedemann syndrome (MIM 130650), an overgrowth disorder notably associated with omphalocele and hepatic anomalies and tumors. However, no hepatic mesothelial cyst has been described in this syndrome. In the 2nd case the omphalocele and the hepatic cysts were the sole lesions observed in the neonate. To the best of our knowledge, these 2 cases represent the first description of such an association.

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.
