Gastric ulcer due to mucormycosis in a critical patient.

We have read the article published by Sánchez-Velázquez P et al., which described a clinical case of gastrointestinal hemorrhage secondary to gastric ulcer due to Mucor. We present a similar clinical case, as an example of one identified by gastroscopy.

Pancreatic metastasis of Merkel-cell carcinoma: a rare neoplasm of the pancreas.

Only 2-3.9% of pancreatic malignancies represent metastases from other sites, the most common origins being the lungs, kidneys, and gastrointestinal tract. Differentiating between primary and secondary lesions may be challenging with imaging techniques but EUS-guided FNA is a safe, accurate procedure for obtaining a tissue diagnosis.

Recurrent small-bowel bleeding from a Dieulafoy's lesion after combined endoscopic treatment.

Introduction: Dieulafoy's lesion of the small bowel is an uncommon cause of gastrointestinal (GI) bleeding that often recurs after endoscopic treatment.

Material And Methods: we report an observational, descriptive, retrospective, single-center study in 15 patients with small bowel bleeding who were diagnosed with a Dieulafoy's lesion by capsule endoscopy or double-balloon enteroscopy.

Results And Conclusions: all patients underwent combined endoscopic treatment.

Klatskin-mimicking neuroendocrine tumor.

With regard to the article published in your journal by Konstantinos Tsalis et al on Klatskin-mimicking lesions, we recently diagnosed a neuroendocrine tumor (NET) in the proximal biliary tract of a 78-year-old female with obstructive jaundice manifestations. A chest-abdomen-pelvis CT scan identified infiltrating ductal cholangiocarcinoma (Klatskin tumor, type IV in the Bismuth-Corlette classification with cT2N1 staging) and a liver mass in segment IV.

A degenerate Todani Ia choledochal cyst in a patient with pancreas divisum.

Bile duct cysts represent congenital abnormalities associated with biliopancreatic maljunction that may undergo malignant degeneration. We report herein the case of a 72-year-old male patient with cholangitis. MR-cholangiography and abdominal CT revealed a mass at the biliary-pancreatic-duodenal crossroads, extrahepatic biliary dilation up to 38 mm, and pancreas divisum.
