Pipe came up with lumps or swellings (8)
I believe the answer is:
tuberose
'lumps or swellings' is the definition.
I can't tell whether this definition defines the answer.
'pipe came up' is the wordplay.
'pipe' becomes 'tube' (synonyms).
'came up' becomes 'Rose' (I've seen this before).
'tube'+'rose'='TUBEROSE'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for tuberose that I've seen before include "Like a potato" , "This plant outs beer, strangely" , "To be sure (anag.)" , "with knobs" .)
