Nonsurgical management of mesenchymal hamartomas of the chest wall
Bibliographic record
Abstract
Background: Mesenchymal hamartomas of the chest wall (MHCW) are extremely rare extrapleural benign tumors. There is increasing utilization of nonoperative management given increased understanding of its benign biological behavior. Methods: A review of cases utilizing nonoperative management was completed. We present a case of complete spontaneous resolution of a MHCW managed nonoperatively with radiologic surveillance for five years. Results: Most reported cases were single case reports, with a total of 12 cases including our patient. From the reported cases on nonsurgical management eight were unilateral (67%), and four bilateral (33%). Two patients with unilateral involvement had multifocal lesions (29%). The majority of unilateral lesions were on the right side (85%). Three patients (27%) underwent subsequent surgical management after an initial period of conservative management. Two of these had bilateral involvement and the lesion was resected on only one side, while the third patient had unilateral multifocal involvement and underwent surgery for the predominant lesion only. Conclusion: Mesenchymal hamartomas of the chest wall are extremely rare extrapleural benign tumors. There is increasing utilization of nonoperative management given increased understanding of its benign biological behavior. We present a case of complete spontaneous resolution of a MHCW managed nonoperatively with radiologic surveillance for five years.

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.
