Histological structure of corticotropinomas and ectopic ACTH-secreting tumours (hematoxylin and eosin stainings). (a) A fragment of basophilic corticotropinoma, ×20. (b) Oxyphilic cell hyperplasia in adenohypophysis, ×20. (c) Typical lung carcinoid, ×20. (d) Metastasis of atypical lung carcinoid to a mediastinal lymph node, ×10. (e) and (f) Appendiceal NET (G2), ×10, 25 mm in diameter, clinically manifested as cyclic Cushing’s syndrome with carcinoid crisis attacks between hypercortisolism cycles. (e) Invasion of the tumour into mesenteric fat. (f) NET metastasis to a mesenteric lymph node.
