Acidophil adenoma

(Science: endocrinology, oncology, tumour) a benign tumour, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes.

Such pituitary tumours may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhoea.
