Abstract:
The Meckels divetriculum has a prevalence of the 0.3-3%. It is surgically removed only when arise a complication or a neoplasia. The Meckels diverticulum tumors are unfrequent and observed in only the 0.5-3.2% of the Meckels diverticula. The 12% of these tumors are a GIST. We report a case of a gastrointestinal stromal tumor with neural immunophenotype, observed in a patient presenting a deep venous thrombosis perhaps with a paraneoplastic origin. We also report some observations about the state of the art about the GIST management and particularly of all of them arising in a Meckels diverticulum.
Insights
Meckel's diverticulum tumors are rare, with gastrointestinal stromal tumors (GIST) accounting for 12%. This case highlights a GIST with neural immunophenotype potentially linked to deep venous thrombosis.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Meckel's diverticulum affects 0.3-3% of the population.
- Surgical intervention for Meckel's diverticulum is reserved for complications or neoplasia.
- Tumors arising from Meckel's diverticulum are infrequent, occurring in 0.5-3.2% of cases.
Observation:
- Gastrointestinal stromal tumors (GIST) constitute 12% of Meckel's diverticulum tumors.
- A rare case of GIST with neural immunophenotype is presented.
- The patient exhibited deep venous thrombosis, possibly paraneoplastic.
Findings:
- The study details a unique GIST presentation within a Meckel's diverticulum.
- Neural immunophenotype was observed in the GIST.
- A potential association between the GIST and deep venous thrombosis is explored.
Implications:
- This case expands understanding of GIST in Meckel's diverticulum.
- It underscores the importance of investigating potential paraneoplastic syndromes.
- Further research into GIST management, especially in rare locations, is warranted.
