Bilateral adrenal neoplasms are associated with metastatic cancer, pheochromocytoma and lymphoma. The coexistence of a unilateral functioning adrenocortical adenoma with contralateral pheochromocytoma is extremely rare. A 52-year-old woman complained of fatigue, headache, palpitation, and progressive weight gain. Hormonal assessment demonstrated high 24 hours urine epinephrine, norepinephrine, and free cortisol. A dexamethasone suppression test (overnight 1 mg, low dose 2 mg) showed insuppressible cortisol. Computerized tomographic scanning revealed a bilateral adrenal tumor. To preserve adrenal function, right adrenalectomy along with left adrenal tumorectomy was performed. Histological finding of the right adrenal tumor was pheochromocytoma and the left adrenal tumor was adrenocortical adenoma. This patient was the first case of a functional adrenocortical adenoma with contralateral cystic pheochromocytoma in Korea. We report the case with a review of the literature.

Efferent loop bezoars rarely occur. However when patients have a history of gastrectomy and gastrojejunal anastomosis, they are sometimes found. Small bowel obstruction by efferent loop bezoar has a mortality rate as high as 30%. Although various endoscopic procedures were reported to remove gastric bezoars, the traditional treatment option of small bowel bezoars is operative management. But as in the cases we describe here, endoscopic procedure may offer an effective alternative for efferent loop bezoars. Bezoars obstructing efferent loop were found in patients with history of gastrectomy and they were removed by endoscopy successfully.

Early esophageal cancer is defined as a tumor invading the mucosa with or without lymph node or distant organ metastasis. In the current guidelines for early esophageal cancer, absolute indication for endoscopic resection include lesions limited to the epithelium or lamina propria mucosa not exceeding two-thirds of the circumference, and relative indications include lesions limited to the muscularis mucosa or the upper third of the submucosal layer and not accompanied by clinical evidence of lymph node metastasis. After endoscopic submucosal dissection for early esophageal cancer, locally recurrent cancer can occur, especially in the case of incomplete resection. Here, we report a rare case of a submucosal tumor-like recurrence after endoscopic resection of early esophageal cancer.

BACKGROUND: Maximum standardized uptake value (SUVmax) and maximum tumor diameter (MTD) have been shown to reflect survival outcome in diffuse large B cell lymphoma (DLBCL). However, applying these values to primary extranodal DLBCL is difficult because they are separate nosological entities with differences in genetic origin. We therefore decided to evaluate whether SUVmax and MTD on 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (18-FDG) positron emission tomography (PET) would affect the survival outcome in primary extranodal DLBCL. METHODS: From October 2005 to November 2010, 76 primary extranodal DLBCL patients receiving R-CHOP therapy were analyzed. All patients had undergone an initial 18-FDG PET/CT and conventional computed tomography (CT) of the neck, chest, abdomen, and pelvis for staging. Median follow-up period was 35 months. RESULTS: The SUVmax and MTD cut-off values were 11.0 and 7.5 cm, respectively. SUVmax> or =11.0 predicted a short progression free survival (PFS, P=0.002) and overall survival (OS, P=0.002). MTD> or =7.5 cm was associated with poor PFS (P=0.003) and OS (P=0.003). High International Prognostic Index (IPI) was also associated with the survival outcome (PFS, P=0.046; OS, P=0.030). Multivariate analysis revealed that SUVmax> or =11.0 (PFS, hazard ratio [HR]=10.813, P=0.024; OS, HR=6.312, P=0.015); MTD> or =7.5 cm (PFS, HR=5.631, P=0.008; OS, HR=4.072, P=0.008); and high IPI (PFS, P=0.027; OS, P=0.046) were independent prognostic factors. CONCLUSION: It appears that both MTD and SUVmax can be independent prognostic factors in primary extranodal DLBCL.

A 75-year-old woman who underwent a total thyroidectomy for papillary thyroid cancer 7 years previously presented with a palpable neck mass. Computed tomography (CT) showed two metastatic masses on the thyroid bed and another mass that looked benign originating from the esophageal wall. Endoscopic ultrasonography (EUS) showed a hypoechoic mass in the esophageal wall that looked similar to a gastrointestinal stromal tumor. The mass on the esophagus had intense fluorodeoxyglucose (FDG) uptake in positron emission tomography-computed tomography (PET-CT), which suggested the possibility of malignancy. Subsequently, after surgery, the mass in the esophagus was confirmed as a metastasis from the thyroid papillary carcinoma. Here we report this unusual case of papillary thyroid cancer that recurred as an esophageal submucosal tumor.

Pyogenic granuloma is a benign inflammatory vascular lesion, mainly found in the skin and oral mucosa. A few cases of pyogenic granuloma in the gastrointestinal tract have been reported, and the esophagus was the main site in these cases. These patients were diagnosed with pyogenic granuloma after they underwent upper endoscopy and biopsy. Endoscopic resection is a favorable treatment option for esophageal pyogenic granuloma. Recently, we observed characteristic endosonographic findings in two cases with esophageal pyogenic granuloma, which were then treated successfully by endoscopic resection.
