N/A: information not available. 1By report, case 6 showed a lymphocytic infiltrate composed primarily of T lymphocytes, demonstrated by positivity for ubiquitin carboxyl-terminal hydrolase L1 (UCHL-1) [12]. 2Case 18 showed cholangiolar differentiation (focal CK19 immunoreactivity) [18]. 3Cases 22 and 23 showed lymphoid infiltrate consisting predominantly of T cells (case 22) or mixed T and B cells (case 23). Immunophenotype of the lymphoid cells is not reported [22].
