Pancreaticopleural fistula: you can only find it if you look for it.

We present a case of a 52-year-old man with chronic toxic pancreatitis and history of multiple hospital admissions secondary to pancreatitis exacerbation. Due to persistent respiratory symptoms a thoracoabdominal computerized tomography (CT) was performed. The CT showed a new significant right pleural effusion as well as inflammatory changes secondary to acute pancreatitis.

Acute pancreatitis due to osteosarcoma metastasis.

We present the case of a young patient with acute pancreatitis (AP) secondary to osteosarcoma metastasis. It is necessary to assess tumor etiology in the study of any acute pancreatitis without clear cause. Pancreatic metastases are rare and difficult to diagnose and differentiate from other primary tumors such as neuroendocrine tumors (NET).

Primary adenocarcinoma of the fourth portion of the duodenum, an unsuspected diagnosis.

Small bowel adenocarcinoma is a rare tumor accounting for only 0.3-0.4% of all gastrointestinal tumors, with duodenal adenocarcinoma being the most common subtype.

Dubin-Johnson syndrome as a laparoscopic finding.

We present the case of a 35-year-old female with a history of polycystic ovary syndrome, treated with oral contraceptives. She was under study due to nine months evolution of pain in the right iliac fossa, associated with hyporexia and mild hyperbilirubinemia with a predominance of the conjugated fraction (total Bi 3.7 mg/dl, conjugated Bi 2.

[Rituximab as rescue therapy in refractory esophageal lichen planus].

Esophageal lichen planus (ELP) is a rare condition with unknown prevalence that can sometimes be underestimated due to the subtle and nonspecific findings of diagnostic workup. Oral lesions rarely extend to the esophageal mucosa, but when they do, the most frequent symptoms are dysphagia and odynophagia. There is often a significant delay in diagnosis and inadequate treatment.

Endoscopic mucosal resection for proximal superficial lesions: efficacy and safety study in 59 consecutive resections.

Introduction: endoscopic mucosal resection is an accepted technique for the treatment of proximal gastrointestinal tract superficial lesions.

Objectives: to evaluate the efficacy and safety of this procedure in the proximal gastrointestinal tract.

Material And Methods: forty one consecutive patients (23 males and 18 females, mean age of 61 ± 11.

[Jaundice secondary to giant pancreatic serous cystoadenoma].

Serous cystadenoma is the second most frequent pancreatic cystic neoplasm and accounts for 1-2% of exocrine neoplasms of the pancreas. Recently, they have been identified more frequently, due to the improvement in imaging techniques. Differential diagnosis should be performed with mucinous cystoadenoma, due to the latter´s potential for malignant transformation.
