Renal leiomyomas large enough to be clinically diagnosed are extremely rare. We review 30 cases of clinically diagnosed renal leiomyoma from the literature in Japan, including our 2 new cases. Case 1: In a 52-year-old man with no symptoms a renal mass was found accidentally on an ultrasonogram. CT scan showed a mass with a cystic area at the upper pole of the right kidney. Angiogram showed a hypovascular mass. Case 2: CT scan revealed a cystic mass and angiogram showed an avascular mass at the upper pole of the left kidney in a 19-year-old man having gross hematuria and left flank pain. Transperitoneal nephrectomy was done in both cases. Histologically each tumor was composed of monotonous proliferation of spindle shaped cells without atypia, which showed intense immunoreactivity for alpha-smooth muscle actin. The diagnosis of benign leiomyoma was made in each case. In a review of 30 cases, we found that renal leiomyomas occur most often in female (77%), between decades 2 and 5 of life (median: 46 years). On the angiogram it appears most often as an avascular or hypovascular mass. CT scan shows cystic or mixed solid/cystic or solid lesion, occasionally with calcification. Preoperative diagnosis is extremely difficult to be made. Histologically, fibroma, angiomyolipoma, congenital mesoblastic nephroma and leiomyosarcoma should be differentiated.

A case of giant renal hamartoma considered as congenital mesoblastic nephroma in an adult is reported. A 24-year-old woman was admitted to our hospital with complaints of macroscopic hematuria and left flank pain. On clinical examination, a large left renal tumor was recognized and radical left nephrectomy was performed. The tumor weighed 2,500 g. On histological examination, the tumor was composed of spindle-shaped cells, that were considered as fibroblasts, surrounded by abundant collagenous interstitial material, and many cystic or tubular structures lined by cuboidal epithelium were also seen in the peripheral region. Because of histological similarity we considered this tumor as congenital mesoblastic nephroma in an adult.

A case of Wilms' tumor in an adult patient is presented. The tumor in adults is rather rare and has an unfavorable prognosis. A 39-year-old man bruised his left flank while skiing in February, 1983. He noticed severe left flank pain. The pain subsided after a week of rest. However, he complained of left abdominal mass and dull pain again, and consulted our outpatient clinic on May 21, 1983. Left transperitoneal nephrectomy was performed under a diagnosis of left injured renal tumor. Histological diagnosis was nephroblastoma. A combined chemotherapy of actinomycin D (ACD) and vincristine (VCR) was started after operation. A total of 10 mg of ACD and 14 mg of VCR was administered by the end of 1983. In March 1984, however, a local recurrence and pulmonary metastases of the tumor were detected by CT and chest films. Local RF-hyperthermia combined with irradiation, alpha-interferon or chemotherapy using cisplatin and adriamycin was given. The patient died of profound cachexia in December, 1984 after gradual deterioration of general conditions.

Renal cell carcinoma in children is extremely rare compared to Wilms tumor. We report on a 7-year-old Japanese boy with left renal cell carcinoma. Since the disease was clinical stage I, nephrectomy with tumor extirpation was performed after a short course of initial chemotherapy had been administered. The patient is free of disease 3 years postoperatively. In a review of the Japanese literature we found 71 reports of renal cell carcinoma in children less than 15 years old. Mean patient age at occurrence was 8.1 years, there were no differences in regard to the sex or the affected side, and the most frequent symptom was the presence of a mass. We stress the early establishment of diagnosis in children with a persistent abdominal mass, hematuria and flank pain, since surgical treatment leads to a favorable prognosis only in the early stage of renal cell carcinoma.

A 35-year old man was hospitalized for left flank pain. IVP showed left non-visualizing kidney with multiple renal calculi. Selective renal arteriogram revealed avascular mass in the left upper pole. The upper calyx was irregularly distorted. Left nephrectomy was carried out. Grossly, the upper pole was replaced by whitish, firm and homogeneous tumor, which was 7 X 7 cm in diameter and protruded into the upper calyx. Histologically, the tumor was composed of both epithelial and mesenchymal components. The epithelial elements consisted of cysts and tubules, and the mesenchymal elements of loosely textured fibroblasts and smooth muscle cells. Other elements could not be identified. This case was diagnosed as renal hamartoma histologically resembling congenital mesoblastic nephroma of infancy. Congenital mesoblastic nephroma is rare in adults. Continued maturation may finally transform it either to benign mixed tumor as in our case or fibromatous tumor if stroma matures dominantly.

A 54-year-old female suffered from repeated flank pain. A large, irregular cystic mass that compressed and distorted the left pelviocalyceal system was found. She underwent left nephrectomy. The cyst arose from the inner zone of the kidney. Although monolocular grossly, it was compatible with the multilocular cystic nephroma on the microscopic examination.

A nephroblastoma (Wilms' tumor) is very rarely found in adult patients. We report on 10 cases to demonstrate the diagnostic and therapeutic problems. In case of flank pain, large tumor mass, fast tumor growth, and young age, the possibility of a Wilms' tumor should be taken into consideration even in adult patients. The chances for a successful treatment by primary surgery with adjuvant therapy are favorable for the lower stages I and II. All our patients presenting with tumor stages I and II have survived and are free of disease since 68 months at the time of the study. One of 2 patients with a Wilms' tumor stage III died 8 months postoperatively, while the other is free of disease since 120 months. In the advanced stage IV no patient survived. In cases of inoperable large tumors in adults, the possibility of primary chemotherapy should be considered under certain circumstances. Rapid tumor regression may confirm the diagnosis and will enable salvage operation in some cases.

Clear cell sarcoma of the kidney is a distinct, highly malignant pediatric neoplasm. Its occurrence in adults is extremely rare and the subject of isolated case reports. We present a series of four cases (three males and one female) identified in an adolescent and in young adults (16, 18, 20, and 25 years) with flank mass (three cases), hematuria (two cases), flank pain (two cases), and hypertension (one case). Three patients had stage III disease and one had stage I disease (National Wilms' Tumor Study staging system). All tumors had predominantly or exclusively the classic histology of a monotonous proliferation of uniform small round cells with evenly distributed fine chromatin, although focal microcyst formation (two cases) and spindled architecture (one case) (variant patterns) were also noted. Therapy in all cases consisted of surgery and chemotherapy with or without radiation. Follow-up data (29-202 months) showed distant metastases in all four cases, including the lung (four cases), bone (two cases), and the liver (two cases). Three patients died of disease at 29, 59, and 63 months (mean, 50.3 months), and one patient is alive with no evidence of disease at 202 months. Ultrastructural features included scattered primitive junctions, short and irregular cytoplasmic extensions, and scant to a moderate amount of mitochondria. Immunohistochemical study (three cases) showed immunoreactivity with vimentin (two cases) and no reaction with cytokeratin, epithelial membrane antigen, S-100 protein, or desmin. Flow cytometric analysis showed diploid DNA content in three primary tumors and tetraploidy in one metastatic tumor. The proliferative activity (S-phase fraction) was low to intermediate (mean, 9.8%). Our data suggest that clear cell sarcoma of the kidney in the young adult age group resembles its pediatric counterpart in ultrastructural and immunohistochemical characteristics, proclivity for skeletal and visceral metastasis, DNA diploid status with relatively low S-phase, and aggressive clinical course. Clear cell sarcoma of the kidney in adult patients, although rare, must be differentiated from sarcomatoid carcinoma, sarcomas, and round cell tumors because of its unique characteristics in comparison to other renal neoplasms.
