“…In de literatuur worden enkele casus van een kiemceltumor in de blaas gerapporteerd. In deze gevallen betreft het echter ofwel een metastase van een kiemceltumor elders [10][11][12][13], ofwel een extragonadale kiemceltumor die zich primair presenteerde in de blaas [14]. Een geval van een kiemceltumor die is ontstaan uit een intra-abdominale testis die doorgroeide in de blaas, was tot op heden nog niet beschreven.…”

SamenvattingDit case report betreft een patiënt met hematurie ten gevolge van een kiemceltumor van de linker testis, welke doorgroeide in de blaaswand. Mannen met een niet-ingedaalde testis hebben een verhoogde kans op het ontwikkelen van een testiculaire kiemceltumor. Bij de 67-jarige patiënt in deze casus werd tijdens cystoscopie een tumor in de blaas gevonden. De patiënt onderging een diagnostische transurethrale resectie van de tumor, laboratoriumonderzoek en een CT-scan, op grond waarvan een stadium 2‑good-risk seminoom van de testis werd gediagnosticeerd. De patiënt werd behandeld met vier cycli van etoposide en cisplatine met nadien een open chirurgische resectie van de restlaesie. Het herstel verliep ongecompliceerd. Bij beeldvorming na zes maanden waren er geen tekenen van een recidief.

BackgroundHepatocellular Carcinoma (HCC) is the most common primary carcinoma of the liver, which mainly metastasizes through the portal vein system.Case presentationHere, we report an extremely rare case in which HCC metastasized to the capsule of an undescended testis in the right inguinal area of the patient. A tumor approximately 8.8 × 7.0 cm in size was found in the patient’s liver during a health check-up. Initially, it was considered a metastatic tumor because the patient was found to have cryptorchidism, which had been left untreated before he presented to our hospital. The patient underwent a radical orchiectomy via inguinal approach, and the resected testis in the right inguinal region was examined via microscopy. The cancer cells were arranged in nests and showed abundant red or clear cytoplasm and marked nuclear atypia. Immunohistochemical staining showed that the tumor cells were positive for CK, CK8/18, AFP, hepatocyte, GCP3, but negative for PLAP, CD10, CD30, CD34, and vimentin.ConclusionAccording to these findings, the tumor in the inguinal region was considered a metastatic HCC arising from the liver, rather than a seminoma that had originated in the undescended testis. We suggest that during the diagnosis of malignancies, metastatic tumors should always be considered in the differential diagnosis even if the original presentation is at rare metastatic sites or concurrent with other disease(s).

Objective To discuss the diagnostic value of multislice spiral tomography (CT) combined with CT angiography (CTA) technology in intra-abdominal undescended testis secondary seminoma cases. Methods We retrospectively analyzed the CT and CTA imaging features of CT and CTA findings of nine patients with an intra-abdominal undescended testis secondary seminoma. Results The tumors in all nine patients were mainly solid, and the average CT value was 38.4 ± 3.4 HU. Low-density areas of various sizes were visible in the tumors, and calcifications were detected in two patients. The tumors in eight patients had a complete capsule, which pressed on the surrounding structures. In one patient, the tumor had an incomplete capsule, which invaded the surrounding structures. Some of the solid tumors showed progressive and slight enhancement on the CT-enhanced scans. The values in the arterial phase, venous phase, and delayed phase were 46.3 ± 5.1 (40–55 HU), 57.3 ± 7.3HU (48–68 HU), and 65.1 ± 7.2HU (56–77 HU), respectively, with an average increase rate of 27.0 ± 7.2 HU. No enhancement was found in low-density areas on the CTA scans, and the supply arteries of the tumors in the nine patients all originated from the abdominal aortic wall 2–3 cm below the renal ostia. These arteries became thickened and tortuous when near the tumors, and there were no branching vessels. In eight patients, the supply arteries of the tumors originated from the posterior tumor and ended inside the tumor, and they originated from anterior of the tumor in one patient. Testicular venous drainage was detected in three patients, and lymph node metastasis in the abdominal aorta detected in two cases. Conclusion An intra-abdominal undescended testis secondary seminoma exhibits a characteristic appearance on CT. CTA shows a three-dimensional testicular vascular pedicle sign of a seminoma. A combination of CT and CTA can improve the diagnostic accuracy of an intra-abdominal undescended testis secondary seminoma.
