Figure 7. Pathological findings (November 6th, 2020). (A) The pelvic specimen shows marked adhesion and stromal invasion with a papillary growth pattern, consistent with epithelioid mesothelioma. (B) Immunohistochemical staining confirmed the diagnosis, showing strong, diffuse positivity for calretinin, indicating a mesothelial origin of the tumor. (C) WT-1 and (D) BAP1 were positive. WT-1 is linked to mesotheliomas, while BAP1 positivity, uncommon in aggressive cases, indicates a less aggressive tumor subtype.
