case_images: Cystoscopy identified a 4-cm whitish mass at the dome of the urinary bladder, with pathological features indicative of adenocarcinoma (Fig. 1).

case_images: A computed tomography (CT) scan of the abdomen was performed on February 3, 2012, which demonstrated masses within the urinary bladder (Fig. 2).

case_images: Two similar 5-cm tumours were present, with various histological morphologies in different areas, featuring reticular, glandular, papillary, microcystic, solid and hepatoid patterns (Fig. 3).
case_images: (A) Patchy and moderate reactivity to alphaFP (magnification, x40). (B) Diffuse and strong reactivity to SALL4 (magnification, x40). alphaFP; alpha-fetoprotein; SALL4, Sal-like protein 4.

case_images: The tumour cells showed immunohistochemical reactivity for antibodies against MNF116, alpha-fetoprotein (alphaFP) and Sal-like protein 4 (Fig. 4), but not against EMA, HCG, placental alkaline phosphatase, CD30 and octamer-binding transcription factor 3/4. The final pathological diagnosis was of a yolk sac tumour.
