From: Metastatic pituitary carcinoma in a patient with acromegaly: a case report
Photomicrograph of a section of the mass removed from the patient’s neck. The numerous dense core granules (long arrow) indicate that the mass originated from neuroendocrine tissue. Two globular fibrous bodies are also present in the section (one marked with the short arrow). The bodies are suggestive of a growth hormone-producing tumor.
