[A case of lipoma of the spermatic cord].

A case of lipoma of the spermatic cord is presented. The patient is a 68-year-old with the chief complaint of indolent swelling of the left scrotal content which had been noticed about a month ago. A firm elastic and walnut-sized mass with positive transillumination was palpable in the left spermatic cord, but ultrasound sonography demonstrated that it was a solid mass. Though the tumor was punctured with a 18-gauge needle, nothing could be aspirated. The tumor was removed and histologically diagnosed as lipoma originating in the left spermatic cord. Including the present case, 38 Japanese cases of lipoma of the spermatic cord are reviewed.

Survival of patients with superficial bladder cancer after treatment: a 10-year retrospective follow-up study.

The clinical aspects of 64 patients with superficial bladder cancer (Ta, T1, T2 according to the TNM classification, International Union against Cancer or Stage O, A, B1 according to Marshall) admitted to the Tsukuba University Hospital were analyzed retrospectively. Treatment of these patients was mainly by transurethral surgery. The overall 10-year survival rate was 73%. Eight patients died and four of them showed an invasive change, the so-called metamorphosis, during the follow-up period. Patients with papillary, pedunculated tumors had better survival rates than those with papillary, sessile tumors. Patients with tumors less than 1 cm in size had better survival rates than those with tumors 1-3 cm in size. There were no statistical differences in survival rates between patients with single and multiple tumors. Up to seven years from surgery, the patients with T2 tumors had lower survival rates than those with Ta-T1 tumors. The patients with grade I tumors had better survival rates than those with grade II tumors. There were no significant differences in recurrence rates related to the grade of the tumor. It is thought that the prognosis of superficial bladder cancer in our series depended mainly on the shape, size, number, depth and grade of the tumor.

[A case of retroperitoneal liposarcoma].

A 77 year-old woman presented with the chief complaint of a mass in the right upper quadrant. The examination on admission including IVP, echography, Ga scintigraphy, barium enema, CT scan, and angiography revealed that the right kidney and ascending colon were displaced by the mass. Under the diagnosis of retroperitoneal tumor, operation was carried out. Most of the mass was resected with the right kidney. The pathological diagnosis of the resected tumor revealed well differentiated liposarcoma. Convalescence was uneventful and the patient has been well and free from disease for 14 months. Based on our experience and the review of the pertinent literature in English and Japanese, we emphasize the importance of definite surgery and close follow up, as liposarcoma is frequently recurrent.

[Chemotherapy of advanced seminoma].

Seminoma is one of the most radiosensitive of the solid tumors. Radiotherapy provides a high cure rate for patients with stage I and II seminoma, but the survival rate of the patients with clinically advanced stage III seminoma is only about 30% in the literature. Our case of advanced metastatic seminoma was treated with cisplatinum, vinblastine and bleomycin. Metastatic tumors in the lung disappeared after chemotherapy but recurred shortly. Then regional radiation was given and the tumors disappeared completely. Subsequent prophylactic chemotherapy was given. In view of the observed chemosensitivity of seminoma, it appears that all patients who present initially with metastatic or bulky retroperitoneal disease should be treated with multiple drug chemotherapy including cis-platinum. Residual tumors can be treated by radiation and surgical resection, which will improve the cure rate of advanced metastatic seminoma.
