I escaped ice maze, suffering rash (6)
I believe the answer is:
eczema
'rash' is the definition.
(thesaurus)
'i escaped ice maze suffering' is the wordplay.
'escaped' indicates named letters should be taken away.
'suffering' indicates anagramming the letters.
'ice'+'maze'='icemaze'
'icemaze' with 'i' taken away is 'cemaze'.
'cemaze' with letters rearranged gives 'ECZEMA'.
(Other definitions for eczema that I've seen before include "Inflammatory skin condition" , "Long-term skin complaint that flares with stress" , "Distressing skin ailment" , "Pimply condition as of adolescence" , "external irritation" .)
