case_images: Histopathology. (a) Primary cecal cancer reveals moderately differentiated adenocarcinoma. (b) Spermatic cord tumor shows moderately differentiated adenocarcinoma, which is compatible with a metastasis from the cecal cancer. (c) Immunohistochemical staining indicates caudal-type homeobox- (CDX-) 2 positive in the spermatic cord tumor. (d) Immunohistochemical staining shows cytokeratin- (CK-) 20 positive in the spermatic cord tumor.

case_images: He had noticed it 6 months previously and observed an increase of its size. He had undergone right radical hemicolectomy for cecal cancer 6 years ago. Histological examination of the extirpated colon specimen showed moderately differentiated adenocarcinoma (Figure 1(a)) with depth of invasion of subserosa, lymphovascular invasion, and metastasis of the paracolic lymph nodes. A histological examination of the SC tumor showed moderately differentiated adenocarcinoma (Figure 1(b)). In an immunohistochemical examination, the tumor cells in the SC were stained for caudal-type homeobox- (CDX-) 2 (Figure 1(c)) and cytokeratin- (CK-) 20 (Figure 1(d)).
case_images: Abdominal CT. Abdominal CT reveals a 3.7 cm diameter slightly enhanced tumor (arrrow) in the right spermatic cord.

case_images: Abdominal computed tomography (CT) scan showed a heterogeneously slight-enhanced mass with noncapsulated irregular shape, 3.7 cm in diameter, suspicious of extending to the adjunct structures (Figure 2).
case_images: Gross appearance of the resected tumor. Gross examination shows grayish-white mass (arrrow) in the cut surface of the resected tumor.

case_images: The resected specimen involved a 4.5 x 3.5 x 3 cm solid mass, with grayish-white tumor in the cut surface, and was located in the lower part of the SC (Figure 3).
