What's the difference between hyperplastic and lymphadenoma?
Hyperplastic
Definition:
(a.) Of or pertaining to hyperplasia.
(a.) Tending to excess of formative action.
Example Sentences:

(11) Careful microscopic examination of end-stage kidneys undergoing dialysis discloses cysts lined with hyperplastic cells.
(12) Fine needle aspirates and touch imprints of 36 hyperplastic (reactive) lymph nodes were tested for the presence of keratin and desmin.

(20) Hyperprolactinemia induced by pituitary grafting resulted in an increase in the pancreatic weights, mainly due to hyperplastic proliferation of the pancreatic acinar glands.
Lymphadenoma
Definition:
(n.) See Lymphoma.
Example Sentences:
