Congenital communicating bronchopulmonary foregut malformation including ectopic pancreatic tissue in an infant

Background Several reports have documented that the pulmonary sequestration is in communication with the gastrointestinal tract and the concept of bronchopulmonary foregut malformation (BPFM) has become more widespread. However, there are few reports of the sequestration associated with the pancreas derived from the foregut. We describe the history and pathophysiology of BPFM including pancreatic tissue in a male infant with respiratory distress. Case presentation A male patient was born at 38 weeks of gestation and weighed 2752 g at birth. He developed pneumonia and was hospitalized at 3 months of age. Chest radiographs and CT scans led to the diagnosis of a lung abscess in the left lower intralobar pulmonary sequestration with aberrant arteries from the abdominal cavity. At 4 months of age, when the abscess had resolved, left lower lobectomy and the resection of the intralobar sequestration were performed. The pulmonary sequestration was conjoined with the esophagus. A fistula was found between the lower esophageal wall and the pulmonary sequestration. An additional small segment of the esophageal wall was excised. Histologically, the mediastinal surface of the sequestration tissue contained pancreatic tissue. Furthermore, esophageal and gastric tissue, cartilage tissue, and ciliated epithelium were confirmed. A definitive diagnosis of BPFM was made. Conclusions We postulated the rare case of a communicating BPFM with intrapulmonary sequestration on one end and the esophagus on the other forming a mass lesion, which included ectopic pancreatic tissue in a male infant.

Combination of ectopic pancreas and intestinal malrotation presenting as non-specific right iliac fossa pain in a SARS-CoV-2 positive patient

We describe the case of a 31-year-old man who presented with a 3-day history of right iliac fossa pain with associated nausea and vomiting. He denied any previous incidents of abdominal pain and had no relevant medical history or family history to note. Given the typical history, examination findings of localised peritonism and infection risk, he was taken to theatre for laparoscopic appendicectomy without diagnostic imaging. Intraoperatively, we noted gut malrotation and an inflammatory jejunal mass which was resected after converting to a mini-laparotomy. The inflammatory mass was reported to be an ectopic pancreatic tissue from histology. Given that this patient had tested positive for SARS-CoV-2 on admission, we propose a possible case of SARS-CoV-2 infection triggering inflammation of the ectopic pancreatic tissue.

Ectopic pancreas appearing as a giant gastric cyst mimicking gastric lymphangioma: a case report and a brief review

Background Ectopic pancreas (EP) is defined as pancreatic tissue that lacks anatomical or vascular communication with the normal body of the pancreas. Despite improvements in diagnostic endoscopy and imaging studies, differentiating ectopic pancreatic tissue from gastric submucosal diseases remains a challenge. Case presentation Here, we present a case of a 44-year-old woman with severe epigastric pain. Initially, gastric lymphangioma was highly suspected due to a well-demarcated protruding mass with a large size that occurred in the submucosal layer of the gastric antrum and appeared as a cystic lesion. The final correct diagnosis of gastric EP was made during surgery. Conclusion Gastric EP with serous oligocystic adenoma appearing as a giant gastric cyst is extremely rare. The difficulty of making an accurate diagnosis and differential diagnosis is highlighted, which may provide additional clinical experience for the diagnosis of EP with serous oligocystic adenoma in the stomach.

Adenoma in Ectopic Pancreas: A Case Report

Introduction: The presence of pancreatic tissue that lacks anatomical or vascular communication with the pancreatic organ has a frequency in autopsy studies that ranges between 0.5% and 13.7%. It is most commonly found in the stomach, specifically in the antrum. Treatment is not clearly established. Surgical resection is recommended in symptomatic patients whose only cause of symptoms is ectopic pancreatic tissue or cancerous formations. Objective: Report a case of ectopic pancreatic adenoma given its low incidence. Case Report: This study reports the case of a 45-year-old male with a history of clinical diagnosis of gastroesophageal reflux disease and a Nissen fundoplication. He presented poor evolution 6 months after the surgery. An endoscopy which revealed postpyloric “polyp” at the level of the duodenal bulb and an inconclusive histopathological study of the same were performed. Reassessment with CT showed a tumor in the first portion of the duodenum measured at 2.2cm, without adenopathies, and a normal-appearing pancreas. It has been made a subtotal gastrectomy and Roux “Y” reconstruction, without complications, with good postoperative evolution, discharged at home on the sixth day. With hematoxylin and eosin technique, the histopathology report reported bile duct adenoma originating in ectopic pancreatic tissue, positive immunohistochemistry for cytokeratin 7 (IHC-7), predominantly expressed by ductal epithelial cells of the pancreatobiliary tract. The patient after surgery had a good clinical evolution and disappearance of symptoms. Conclusion: The clinical cases of rare pathologies are presented to increase the world bibliography and to be able to compare the diagnosis and treatment. In this case, a heterotopic pancreatic adenoma was presented, which is a diagnostic challenge.

Ectopic Pancreas Tissue in the Gallbladder: An Incidental Mass in Laparoscopy

Ectopic pancreatic tissue (EPT) is a congenital pancreatic tissue located in a location other than the normal anatomical site of the pancreas. It is usually asymptomatic and can be detected during surgical procedures or postoperatively in pathology examinations. The importance of EPT is the possibility of malignant transformation, although rare. It can mimic malignant masses. Since preoperative diagnosis is often unlikely, resection is the preferred method. We report a case with gallstones who underwent elective cholecystectomy. EPT was detected in the gallbladder.

A Case of Heterotopic Pancreatic Tissue Discovered in the Distal Esophagus

Heterotopic pancreas (HP) is a congenital abnormality that represents ectopic pancreatic tissue that does not have anatomic, vascular, or ductal continuity. The prevalence of HP is 0.55% to 13.7% on autopsy, 0.2% to 0.5% of abdominal operations, and 0.9% of gastrectomies. It is commonly found in the stomach, duodenum, and proximal jejunum. Only 15 cases have been reported in the medical literature regarding involvement of the esophagus. Treatment depends on symptoms and location. In asymptomatic patients, simple observation may be sufficient; however, in those who are symptomatic, surgery may be warranted. We present a case of a 70-year-old male with heartburn, nausea, and abdominal bloating who underwent a diagnostic esophagogastroduodenoscopy (EGD) and was found to have HP on histology in the distal esophagus. In our case, symptoms were treated conservatively and successfully with a proton pump inhibitor (PPI).

Esophageal Ulcer Due to Ectopic Pancreatic Tissue: A Case Report

Heterotopic pancreatic tissue, known as pancreatic rest, is a pancreatic tissue that lacks anatomic and vascular continuity with the main body of the pancreas. Common locations for this tissue include the stomach, duodenum, jejunum, Meckel diverticulum, and ileum. In this report, we present a case of a patient whose pancreatic rest was diagnosed primarily during the investigation of dysphagia with solid foods and it was located in the mid esophagus as an unusual location.
