Isolated Colonic Metastasis From Esophageal Adenocarcinoma.

Esophageal cancer is an aggressive and highly lethal malignancy that has a high death-to-incidence ratio approaching 0.90. We present a 60-year-old man with a history of Barrett's esophagus, presented with dysphagia. An upper endoscopy with biopsy confirmed invasive esophageal adenocarcinoma (EAC). Workup, including positron emission tomography scan, showed no evidence of metastasis. A preoperative colonoscopy showed a nodule in the ascending colon that was proven later to be a metastatic lesion from the esophageal primary tumor. Esophageal adenocarcinoma with an isolated colonic metastasis is an extremely rare presentation of esophageal metastasis. These metastatic lesions may not be detected by the positron emission tomography scan.

Esthesioneuroblastoma with widespread distant metastasis: Case report and literature review.

Esthesioneuroblastoma (ENB) is an uncommon sinonasal tract tumor, and it is even more uncommon among all neoplasms. Literature regarding the incidence and spread of the disease is limited. The prognosis of metastatic disease is poor. In this report, we present a case of recurrent ENB in a young woman involving metastasis to the neck, lungs, and ovary. Metastasis to the cervical lymph nodes is relatively common, but metastasis to the lungs is rare. Furthermore, to our knowledge, no cases of ovarian metastases of ENB have been reported. This case highlights the potential for widespread metastatic disease, suggesting the need for more frequent and thorough surveillance of patients diagnosed with recurrences of this tumor.

"A Large Hiatal Hernia": Atypical Presentation of Gastric Volvulus.

Gastric volvulus is a rare condition defined as an abnormal rotation of the stomach by more than 180 degrees. Gastric volvulus could present atypically with simply nausea and vomiting. A high index of suspicion is required for prompt diagnosis and treatment, especially when a patient presents with subacute intermittent gastric volvulus. Here, we present the case of a 56-year-old female with lung cancer status post left lower lobectomy undergoing chemotherapy who presented with intermittent nausea and upper abdominal pain for a few weeks. Barium study and computed tomography revealed acute mesenteroaxial gastric volvulus and she was treated with urgent surgical intervention.

Hemoperitoneum as a Consequence of Colonoscopy.

Hemoperitoneum without evidence of organ damage is a rare complication of colonoscopy. It is most frequently seen in association with splenic rupture due to traction on the splenocolic ligament. In our case, we present a 48-year-old cirrhotic man who developed peritoneal bleeding during a diagnostic colonoscopy for iron deficiency anemia. However, he was without signs of splenic damage or colon perforation. We suggest that the most likely source of bleeding is a ruptured portal-caval collateral vessel based on a computed tomography performed following the procedure.
