Abstract Juvenile granulosa cell tumors (JGCTs) are rare ovarian tumors with overall good prognoses. They differ from adult granulosa cell tumors (AGCTs), which are well known for late recurrence. Most JGCTs (~97%) occur in individuals <30 years old. We report a recurrent JGCT in a 40-year-old woman 5 years after initial presentation. The histological appearance and lack of 402C>G missense point mutation of FOXL2 gene (characteristic of AGCT but absent in JGCT) allowed differentiation from AGCT. This is the first comprehensive report of JGCT with late recurrence. Although rare, late recurrence of JGCT can occur; long-term surveillance is suggested.

Abstract Urothelial carcinoma usually presents with hematuria, but cases of multiple lymphadenopathy with elevated S-pancreas-1 antigen (SPan-1) levels have not been reported. A 62-year-old Japanese man with lymphadenopathies was diagnosed with an adenocarcinoma of unknown origin and transferred to our hospital for further diagnosis. Serum carbohydrate antigen 19-9 and SPan-1 levels were extremely elevated. Uroplakin III immunostaining was positive in the inguinal lymph node, and cystoscopy revealed the presence of invasive urothelial carcinoma. Treatment with cisplatin and gemcitabine promoted a complete metabolic response for > 4 years. The detection of uroplakin III and serum SPan-1 might help diagnose urothelial carcinoma.

Abstract Nephron-sparing treatment should be offered whenever possible to avoid dialysis in allograph cases. Cryoablation is a new treatment option for treating small-sized renal cell cancer (RCCs). We report a case of RCC arising in a kidney allograft treated by cryoablation. To our knowledge, this is the first case in Asia of RCC in a renal allograft treated using cryoablation. Contrast-enhanced CT-guided percutaneous renal needle biopsy and cryoablation were used to identify the RCC, which could not be identified by other techniques. The postoperative course was uneventful. Contrast-enhanced CT also showed no recurrence or metastases at the 6-month follow-up.

Abstract Metastatic prostate cancer (PCa) cases that cannot be detected on repeat prostate biopsy are extremely rare. Our patient was a 51-year-old Japanese man diagnosed as metastatic PCa by histopathological examination of lesions obtained bone biopsy and lymph node dissection. The primary tumor was not detected after repeated prostate biopsy. Metastatic PCa was diagnosed based on immunohistochemical staining: PSA, AR, P504S, and NKX3.1 of bone and lymph node with metastasis. We speculate that the primary PCa was “burned-out,” demonstrating remote metastases with no apparent primary tumor in the prostate. Burned-out PCa may be difficult to diagnose and treat due to its rarity.
