Ruptured Small Intestinal Stromal Tumor Causing Concurrent Gastrointestinal and Intra-Abdominal Hemorrhage: A Case Report

Gastric Antral Gastrointestinal Stromal Tumor Presenting With Severe Anemia

Gastrointestinal stromal tumors are rare gastrointestinal tract growths associated with high rates of malignant transformation. Most cases are asymptomatic and can be identified by computed tomography scan. We present the case of a 50-year-old male with melena and fatigue. Endoscopy showed an ulcerated submucosal tumor diagnosed as a gastrointestinal stromal tumor after surgical resection; it did not present with metastasis and was successfully treated surgically without relapse.

Ruptured gastro-intestinal stromal tumor as a surgical emergency: A case report and literature review

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. GISTs of the small bowel are rare, and often present with an abdominal mass and/or bleeding. Chemotherapy and surgery are the mainstay of therapy. Here, we discuss an unusual case of a ruptured jejunal GIST with hemoperitoneum and recurrence despite surgical excision followed by Imatinib treatment. Forty-five cases of ruptured small intestinal GISTs were identified in the literature. Most cases were in males and were found to be at the site of the jejunum.

Wandering small intestinal stromal tumor: A case report

BACKGROUND

The occurrence of gastrointestinal stromal tumors (GISTs) in the small intestine is rare, and a case of wandering small intestinal stromal tumor has been rarely reported to date. Dissemination of this case can help inform future diagnosis and effective treatment.

CASE SUMMARY

A 68-year-old patient presented to us with tarry stools. Computed tomography showed a mobile tumor moving widely within the abdominal cavity. As the laboratory data showed a low range of red blood cells and an immediate surgery was not indicated, we performed digital subtraction angiography and embolization to achieve hemostasis. Surgical resection was performed after the patient’s condition improved. The tumor was successfully removed laparoscopically. Histological examination revealed submucosal GIST with infarction, which was of intermediate-risk, with mitotic count < 1 per 10 high-power field. Immunohistochemical studies revealed the following: CD117+, Dog1+, CD34+, SMA+, S100-, CK-, Des-, SOX-11-, STAT6-, Ki67 Hotspots 10%+. The patient was ultimately diagnosed with wandering small intestinal stromal tumor.

CONCLUSION

When a highly vascularized tumor is clinically encountered in the small intestine, the possibility of stromal tumors should be considered. However, when the tumor cannot be visualized at its original location, the possibility of tumor migration is considered.
