case_images: The mucin had extravasated to the surrounding tissue and elicited a histiocytic reaction (Figure 1).

case_images: The CT of the abdomen revealed an ill-defined, solid mass at the right adnexa measuring 3.2 cm that could represent ovarian metastases or a metastatic lymph node; an inguinal lymph node measuring 1.6 cm was also noted on the left side (Figure 2).

case_images: A CT-guided biopsy of the thickened sacral area was also obtained and revealed adenocarcinoma (Figure 3).

case_images: She received a dose of 45 Gy in 28 fractions to the entire pelvis and inguinal area, with concomitant 58.8 Gy delivered to the sacral mass and the enlarged inguinal lymph node (Figure 5).
