Mediastinal Ectopic Pancreas with Abundant Endocrine Cells Coexisting with Mediastinal Cyst and Thymic Hyperplasia

Figure 2

(a) An Island of pancreas tissue bordered by thick fibrous tissue with pancreatic interlobular duct around it (H&E-4x). (b) Pancreas tissue consists of exocrine gland with eosinophilic granular cytoplasm and endocrine cells (Islets of Langerhans) (H&E-10x). (c) Increase in the endocrine portion (Islets of Langerhans) of pancreatic tissue (H&E-40x). (d) Mediastinal cyst lined by simple cuboid and columnar epithelium (H&E-10x). (e) Hyperplasia of thymic gland was observed (HE-4x). (f) Normal appearance of lymphocytes and Hassall’s corpuscles (H&E-10x).
