FIGURE 3

The mucin immunocytochemical profile of pseudomyxoma peritonei with metastatic involvement of the ovary (A) contrasts with that of a primary ovarian mucinous adenocarcinoma (B) exhibiting papillary areas in this section—other areas were invasive; intense MUC2 immunoreactivity is observed in the metastases to the ovary (C); the primary ovarian mucinous adenocarcinoma is MUC2 non-immunoreactive (D); both tumors again share MUC5AC immunoreactivity (E,F). A, hematoxylin and eosin, x250; B, hematoxylin and eosin, x250; C, anti-MUC2, immunoperoxidase, x250; D, anti-MUC2, immunoperoxidase, x250; E, anti-MUC5AC, immunoperoxidase, x250; F, anti-MUC5AC, immunoperoxidase, x250
