| pubmed-article:2399812 | pubmed:abstractText | The histological, ultrastructural and immunocytochemical features are reported of an intrasellar neuronal and lipomatous hamartoma associated with pituitary growth hormone (GH) cell adenoma and acromegaly. Electron microscopy demonstrated a close contact between neurons and adenomatous GH cells. By immunohistochemistry the adenoma cells revealed a positive staining for GH and prolactin. The neurons of hamartoma showed neurosecretory activity which might have induced the development of pituitary GH cell adenoma. | lld:pubmed |
