Gastric fundus splenosis with hemangioma masquerading as a gastrointestinal stromal tumor in a patient with schistosomiasis and cirrhosis who underwent splenectomy
Bibliographic record
Abstract
RATIONALE: Splenosis is the heterotopic auto-transplantation of the splenic tissues. Gastric splenosis in a rare location mimics a gastrointestinal stromal tumor (GIST). Gastric splenosis with hemangioma has not been reported throughout the literature. PATIENT CONCERNS: We report a case of a 74-year-old schistosomiasis cirrhosis splenectomy woman diagnosed with gastric fundus mass. Preoperative computed tomography and endoscopic ultrasonography revealed findings suggestive of a GIST. DIAGNOSES: The mass located in the gastric fundus muscularis propria, measuring 3.9 × 2.8 × 2.4 cm with a dark red color, was removed by surgery. In the mass, a 1 × 1-cm red-purple nodule was also found. On microscopic examination, a well-formed splenic tissue divided into two compartments-white pulp and red pulp-separated by an ill-defined interphase known as the marginal zone. However, a nodule in the heterotopic spleen was mainly composed of larger thin-walled muscular vessels. The final diagnosis was gastric splenosis with hemangioma. INTERVENTIONS: After discussion in a multidisciplinary conference, the patient was considered for a GIST resection under gastroscopy. In the process of peeling, the surface of the mucosal, submucosal, muscle layers and the tumor surface were diffusely oozing. The effect of electrocoagulation and hemostasis was extremely poor. Therefore, endoscopic surgery was arrested. After dealing with the patient's family, a combination of laparoscopic-gastroscope double-mirror surgery was decided in accordance with the principle of minimally invasive surgery to preserve the stomach. Owing to several adhesions and concealed the location of tumor, we stopped the double-mirror combination surgery plan. Considering the great possibility of a malignant GIST, we still decided to continue the traditional surgical resection. The tumor was then removed via surgery OUTCOMES:: The patient was favorable with healing and discharged on postoperative day 10. LESSONS: Gastric splenosis with an associated hemangioma is the first well-documented case. Its pathogenesis may be direct implantation. Appropriate medical history taking and Tc-99 m heat-denatured RBC spleen scintigraphy (Tc-99MHDRS) are valuable for its diagnosis; however, pathology is the gold standard. Surgery is a reasonable treatment for gastric splenosis with hemangioma.

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.
