Neuroendocrine Cancers

Gastric neuroendocrine tumors (NETs) are rare lesions that arise from enterochromaffin-like cells of the gastric mucosa. Gastric NETs are classified into 3 types of NETs and poorly differentiated neuroendocrine cancers. Most gastric NETs usually present as hemispherical, yellowish, polypoid lesions with a central depression and often as subepithelial tumors (SETs) because they are confined within the submucosal layer. Here, we report a case of gastric NET presenting as SET mimicking a gastrointestinal stromal tumor (GIST). Endoscopy revealed a 2.3-cm-sized SET with intact surface mucosa, and endoscopic ultrasonography showed a homogeneous hypoechoic lesion with a well-circumscribed margin. Typical features of gastric NET, such as yellowish mucosal changes or central ulceration, were not observed. GIST was suspected, and a laparoscopic wedge resection was performed. The final diagnosis was gastric NET with grade 2 differentiation.

Mesenchymal Tumors

Gastrointestinal stromal tumors (GISTs) represent the majority of primary mesenchymal tumors of the gastrointestinal tract. They are generally considered to be solitary tumors and therefore the synchronous occurrence with other primary malignancies of gastrointestinal track is considered a rare event. Here we present the case of a 75-year-old man admitted to our hospital with a 10-day history of gastrointestinal bleeding. Colonoscopy revealed an ulcerative mass of 4 cm in diameter in the ascending colon. Gastroscopy revealed a bulge in the gastric body measuring 1 cm in diameter with normal overlying mucosa. Surgical intervention was suggested and ileohemicolectomy with regional lymph node resection along with gastric wedge resection was performed. Pathologic examination of the ascending colon mass showed an invasive moderately differentiated adenocarcinoma stage III B (T3N1M0). Grossly resected wedge of stomach showed a well circumscribed intramural tumor which microscopically was consistent with essentially benign gastrointestinal stromal tumor (according to Miettinen criteria). The patient did not receive additional treatment. Two years later the patient showed no evidence of recurrence or metastasis.

Introduction. Meckel?s diverticulum is the most common congenital anomaly of the gastro intestinal tract, present in about 2% of population. Case Outline. The article presents the case of a 44-year-old otherwise healthy man with anemia, who was diagnosed lower gastrointestinal bleeding. An abdominal CT scan revealed a clearly demarcated solid tumor in hypogastric region, measuring 65 ? 45 mm. A laparotomy through lower midline incision was performed. A surgical resection of a lesion of a Meckel?s diverticulum was carried out and a final diagnosis of gastrointestinal stromal tumor was made. The patient made an uneventful recovery. Conclusion. The preoperative diagnosis of a complicated Meckel?s diverticulum may be challenging. CT is usually an adequate method to diagnose tumors arising from Meckel?s diverticulum.
