Coexistence of Pheochromocytoma and Primary Aldosteronism due to Multiple Aldosterone-producing Micronodules in the Ipsilateral Adrenal Gland.

A 46-year-old woman was referred for hypertension and a right adrenal tumor. Primary aldosteronism (PA) was suspected because of the high plasma aldosterone concentration-to-plasma renin activity ratio. However, a subsequent evaluation revealed coexistent PA and pheochromocytoma.

Implantation of sigmoid colon cancer into the endoscopic resection site of intramucosal rectal cancer: A case report.

A 70-year-old woman was diagnosed with intramucosal rectal cancer and advanced sigmoid colon cancer at the same time. First, the intramucosal rectal cancer was curatively resected by endoscopic submucosal dissection, and surgery was subsequently performed for sigmoid colon cancer.

A desmoid-type fibromatosis in the retroperitoneum of the gastro-pancreatic region that was resected with a distal pancreatomy: a case report.

An 80-year-old man was referred to our hospital because of epigastric pain. Abdominal computed tomography revealed a well-defined circular intra-abdominal mass in the gastro-pancreatic region measuring 15 mm in diameter. After 6 months, the mass lesion was growing with mild enhancement, and weaker enhancement was found in the lower half of the mass on contrast-enhanced computed tomography.
