Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

OBJECTIVETo study the clinicopathological features and prognosis of renal cell carcinoma with sarcomatoid differentiation (RCCS).
METHODSThe clinical data and pathological materials of 18 RCCS cases were retrospectively reviewed.The follow up data were available in 13 RCCS cases, and were compared with the follow up data of 20 cases of clear cell renal cell carcinoma (RCC).
RESULTSThe 18 RCCS patients included 14 males and 4 females, and were 49-79 years old (mean age: 62 years old). On gross examination, the tumor size was 3-19 cm in diameter (mean diameter: 9.8 cm). Histologically, all tumors were composed of a mixture of typical RCC with sarcomatoid component, including 9 clear cell RCC, 3 chromophobe RCC and one papillary RCC. The sarcomatoid components included 9 cases of fibrosarcoma, 3 cases of leiomyosarcoma, 5 cases of malignant fibrous histocytoma and one case of undifferentiated sarcoma. Immunohistochemistry showed that the sarcomatoid components were strongly vimentin-positive in 18 cases, and one or more epithelial markers (EMA, AE1/AE3, CK7, CK18) were expressed to varying degrees in 14 cases, but the high-molecular weight keratin 34βE12 was scarcely expressed. The sarcomatoid components presented positive expressions of CAIX in 88.9% (16/18) and CD10 in 72.2% (13/18) cases. Among the 18 RCCS patients, 13 patients were followed-up: 9 patients died in 1-25 months after the surgery, of which 5 cases died of lung or bone metastasis, and 4 patients died of systemic failure. The twenty RCC cases without sarcomatoid differentiation were followed up for 3-65 months after the surgery, and the majority of them was alive uneventfully except for 2 cases who died of lung or bone metastasis of the tumor. The Kaplan-Meier survival analysis showed that the median survival time of the 18 RCCS patients was 8 months, while that of the 20 RCC cases without sarcomatoid differentiation was 62 months (P<0.001).
CONCLUSIONSThe presence of sarcomatoid differentiation in renal cell carcinoma indicates highly aggressive behavior and poor prognosis. The positive expressions of the immune markers CAIX and CD10 may play important roles in the transformation from renal cell carcinoma to sarcomatoid component.
