Figure

• 

  Fig. 1. Computed tomography urography. (A) Images taken three months before the surgery demonstrate a 4.9-cm-sized right seminal vesicle cyst (arrowhead) and an exophytic tumor measuring up to 3 cm (arrow). (B) Images taken three months later show a 4.7-cm-sized seminal vesicle cyst (arrowhead) with an enlarged mass (arrow) bulging to the left prostate gland (6.1 cm).

• 

  Fig. 2. Histopathologic findings of the right seminal vesicle cyst. The specimen shows squamous metaplasia (insert), glandular tissues (A), and a poorly differentiated carcinoma (B).

• 

  Fig. 3. Immunohistochemistry and histochemical staining for phenotyping of the carcinoma. Tumor cells are positive for p63 (A), and negative for cytokeratin 7 (B), cytokeratin 20 (C), and carcinoembryonic antigen (D). Vimentin shows focal positivity in macrophages (E), and periodic acid–Schiff staining is positive for mucin (F).
