case_images: Sagittal US image of the lower abdomen obtained with a convex probe (1-6 Mhz). Large mass filled with gas (star), contacting the superior bladder wall (arrow), with focal thickening. Presence of free abdominal fluid is noted.

case_images: It revealed a midline mass with a central gas-filled cavity contacting the superior bladder wall and extending to the anterior abdominal wall (Figure 1).
case_images: (a) 3D CT reconstruction showing an emaciated patient with a visible infraumbilical mass (arrow). Axial (b), coronal (c), and sagittal (d) contrast-enhanced CT images depicting a large and heterogeneous median abdominal mass, extending from the anterosuperior aspect of the bladder toward the umbilicus.

case_images: Inferiorly it contacted the bladder dome, and anteriorly there was infiltration of the entire thickness of the anterior abdominal wall, invading the umbilicus (Figure 2).
case_images: Gross specimen of the tumor ((a) anterior view; (b) cross section), showing a multinodular mass with fistulization to the umbilical skin (black arrows) and involvement of the bladder wall (red arrow) and a central necrotic cavity (star). Histologic image of the resected tumor ((c) H&E 100x; (d) H&E 400x) showing areas with a mucinous pattern (blue star) and a signet ring cell morphology (blue arrow).

case_images: It infiltrated the skin, as well as the colonic and bladder walls, with mucosa ulceration (Figure 3).
case_images: (a) Histologic image of the resected tumor (cytokeratin 34-beta-E12, 100x). Most of the neoplastic cells expressed high molecular-weight cytokeratins (black arrow). (b) Neoplastic cells showing diffuse membranous and cytoplasmic expression of beta-catenin (blue arrow). Note that there is no nuclei staining (beta-catenin, 400x).

case_images: Radiologic-pathologic correlation of the tumor ((a) sagittal CT image; (b) cross section of the gross specimen), showing a large and heterogeneous mass, with thickened wall and central necrotic cavity.
