Half-hidden story about glands (8)

I believe the answer is:

thyroids

'glands' is the definition.
(thyroid is a kind of gland)

'half-hidden story about' is the wordplay.
'half' suggests halving the letters.
'about' is an anagram indicator.
'hidden' cut in half is 'hid'.
'hid'+'story'='hidstory'
'hidstory' anagrammed gives 'THYROIDS'.

(Another definition for thyroids that I've seen is " Neck glands".)

I've seen this clue in The Independent.
