Pancreatic cancer is sometimes called a "silent disease" because it often causes no symptoms in the early stage. The symptoms can be quite vague and various depending on the location of cancer in the pancreas. The anatomic site distribution is 78% in the head of the pancreas, 11% in the body, and 11% in the tail. Pancreatic cancer is rarely detected in the early stage, and it is very uncommon to diagnose pancreatic tail cancer during an emergency department visit. The manifestation of pancreatic tail cancer as left flank pain is very rare and has seldom been identified in the literature. We present a case of pancreatic tail cancer with the sole manifestation of dull left flank pain. Having negative findings on an ultrasound study initially, this female patient was misdiagnosed as having possible acute gastritis, urolithiasis or muscle strain after she received gastroendoscopy and colonofiberscopy. Her symptoms persisted for several months and she visited our emergency department due to an acute exacerbation of a persistent dull pain in the left flank area. Radiographic evaluation with computed tomography was performed, and pancreatic tail tumor with multiple metastases was found unexpectedly. We review the literature and discuss this rare presentation of pancreatic tail cancer.

Acute oxalate nephropathy can occur due to primary hyperoxaluria and secondary hyperoxaluria. The primary hyperoxalurias are a group of autosomal recessive disorders of endogenous oxalate overproduction. Secondary hyperoxaluria may occur as a result of excess dietary intake, poisoning with oxalate precursors (ethylene glycol), or enteric hyperoxaluria. The differential diagnosis of enteric hyperoxaluria includes inflammatory bowel disease, short bowel syndrome, bariatric surgery (with jejunoileal bypass or Roux-en-Y gastric bypass), celiac disease, partial colectomy, and chronic pancreatitis. The common etiology in all these processes is fat malabsorption, steatorrhea, saponification of calcium, and absorption of free oxalate. Hyperoxaluria causes increased urinary oxalate excretion, urolithiasis (promoted by hypovolemia, decreased urinary pH caused by metabolic acidosis, and decreased citrate and magnesium concentrations in urine), tubulointerstitial oxalate deposits, and tubulointerstitial nephritis. We report a rare case of acute oxalate nephropathy due to pancreatic atrophy and exocrine insufficiency caused by newly diagnosed pancreatic cancer.
