Figure 2 Pathological findings. A: Small nodules of atypical epithelioid cells on the surface of peritoneal serosa noted during frozen section examination (original magnification 200 ×); B: On definitive histopathological analysis, although atypicality of cell proliferation and areas of isolated growth patterns are observed, there is an evident histological overlap between peritoneal carcinomatosis and nodular histiocytic/mesothelial hyperplasia (original magnification 200 ×).
