The descriptive term "mixed epithelial and stromal tumor of the kidney" was recently proposed for a group of renal tumors characterized histologically by a mixture of stromal and epithelial proliferation. It is a rare benign neoplasm of the kidney which has been reported under various names such as adult type mesoblastic nephroma or others. We report a case of mixed epithelial and stromal tumor in a 47 yr old female patient presenting as a partly cystic and partly solid renal mass. Microscopically, the tumor exhibited spindle cell component in solid portion and epithelial proliferation around microcystic areas. Immunoreactive profiles and ultrastructural examination suggested myofibroblastic nature of the stromal cells. We believe this case exemplifies a unique adult renal tumor displaying both epithelial and stromal neoplastic component and has a few unusual features worthy of attention.

A 51-year-old male patient was presented to our hospital for inspection of right renal space-occupying lesions. CT revealed soft tissue density in the right renal pelvis and renal pelvis ureter transitional crumb, for which a clinical diagnosis of right renal cancer was made. After laparoscopic radical resection of the right kidney, pathological examination supported the diagnosis of idiopathic retroperitoneal fibrosis. With an unclear pathogenesis, idiopathic retroperitoneal fibrosis presents with atypical clinical manifestations but shows specific features in imaging examination. Its treatment is individualized according to the specific condition for which conservative medical or surgical treatment can be considered. Retroperitoneal fibrosis has a low incidence and a high misdiagnosis rate, and imaging examinations remain currently the primary modality for diagnosis with specific findings.

Epithelioid angiomyolipoma is a recently described rare variant of renal angiomyolipoma. It can occur in patients with or without tuberous sclerosis. We report the imaging findings of a case of epithelioid angiomyolipoma that showed the presence of fatty tissue undifferentiated from the typical angiomyolipoma at the beginning. After partial nephrectomy, tumour recurrence occurred two years later, presenting as completely solid tumours with no adipose tissue, and with invasion into the psoas muscle and left adrenal gland. Differentiation of this tumour from renal cell carcinoma is difficult. Both the radiologist and surgeon should be aware of the existence of this tumour and its potentially malignant behaviour.

Alveolar soft part sarcoma (ASPS) is an extremely rare malignant soft tissue sarcoma primarily affecting young patients. It usually occurs in the lower extremities, although it can occur in soft tissue anywhere in the body. However, to our knowledge, there has been no case of primary ASPS originating from the kidney in the literature. We herein present the imaging and clinical features of an ASPS which occurred in a 16-year-old male presented as a palpable mass in the left side of the abdomen.

Multilocular cystic nephroma is a rare disease, noninherited benign renal neoplasm occurring in both children and adults. It is necessary to make a differential diagnosis from all renal diseases with a cystic component, such as Wilms tumor, armatoma or polycystic dysplastic kidney in childhood. There are about only 200 case reports in the world since Walter Edmunds had described it first. We report a case of multilocular cystic nephroma presented with painless abdominal mass, treated with nephrectomy and confirmed with pathology.
