With
A1:E1 always containing 5 text values
Example:
A1: United_Kingdom
B1: France
C1: United_Kingdom
D1: United_Kingdom
E1: United_Kingdom

This formula returns the unique values, concatenated into one cell
F1: =A1&IF(MATCH(B1,A1:E1,0)=COLUMN(B1),", "&B1,"")&
IF(MATCH(C1,A1:E1,0)=COLUMN(C1),", "&C1,"")&
IF(MATCH(D1,A1:E1,0)=COLUMN(D1),", "&D1,"")&
IF(MATCH(E1,A1:E1,0)=COLUMN(E1),", "&E1,"")

In the above example, the formula returns: United_Kingdom, France

Is that something you can work with?
