Patient 1 was originally diagnosed with superficially invasive (24%) grade 1, ERα+/PR+, endometrioid adenocarcinoma (FIGO stage IB) and presented two years later at our institution with a 20 × 21 × 10 cm mass involving the omentum, anterior abdominal wall, and bowel, which was resected. This evidence concerns the gene PGR and endometrioid adenocarcinoma.
