In each subtype of carcinomas (except for those named ‘other carcinomas’), score 2 was given in 50–60% of the cases. In solid and tubulopapillary carcinomas, score 3 represented 30–40% of the cases, while in complex carcinomas only 19% of cases were scored 3. In the latter, 29% had a score of 1 in nuclear grade ( Table 2 ).
